HW video decode and XBMC support on a Pandaboard with Ubuntu LEB

Part of the effort we spent during the Linaro 11.12 cycle was to try to enable at Pandaboard not only hardware graphics support (GLES with PVR SGX), but also hardware accelerated video decode, as TI had released all needed userspace to be used at Ubuntu Oneiric (11.10) release.

Unfortunately it didn’t just work with our images because at that time we were using a newer kernel already, based on the 3.1 series that is maintained by the Linaro TI Landing Team. Bug 880840 has all the details.

Luckily Sebastien Jan (from TI) was able to find the root cause of the problem, that was causing so much frame drops that was making the video playback basically unusable. The problem was related with PM support at omap’s hwspinlock implementation, as you can check at this link.

Kernel fix properly integrated and available at the Overlay PPA used by our Linaro Ubuntu Evaluation Build images, and finally able to have a similar user experience as was expected when TI delivered the user space components at their own PPA.

If you want to try it by yourself, just be sure you’re using at least linux-image-3.1.1-6-linaro-lt-omap at your board (all hwpacks >= 20110105 should have it included by default).

Playing videos with HW decode acceleration

Since today you’ll also easily find all the needed packages to enable HW video decode acceleration at our images (Pandaboard only at the moment, more boards coming soon). We just included and copied all needed packages from the TI PPA, so you don’t even need to enable it when installing the additional packages.

Installing the extra packages for video decode at your Pandaboard:

Grab the latest Pandaboard hwpack (lt-panda-x11-base-oneiric) and Ubuntu Desktop image from http://snapshots.linaro.org/oneiric (as example I used hwpack_linaro-lt-panda-x11-base_20120106-0_armel_supported.tar.gz and linaro-o-ubuntu-desktop-tar-20120105-0.tar.gz)
Create a Ubuntu LEB pandaboard image on a SD card, following the instructions described at https://wiki.linaro.org/Platform/DevPlatform/Ubuntu/ImageInstallation
Boot the card and install the ubuntu-omap4-extras-multimedia package: $ sudo apt-get install ubuntu-omap4-extras-multimedia
Reboot your pandaboard
Play a video with any video player that’s compatible with Gstreamer (e.g. Totem)

In the future we should also have this completely integrated at the hwpack itself, but unfortunately this is not possible at the moment without increasing the image size too much.

XBMC support

Another awesome thing we worked during previous cycle (11.12) was to make an XBMC version available that would use both GLES and Gstreamer, so it could also be used with a Pandaboard. Avik Sil did a great work making it all work with our images, and we were finally able to have XBMC 11 Beta (Eden) available at our Overlay PPA.

For proper support for Gstreamer Rob Clark did an awesome work improving the current patches, and also improving the support quite a bit. At our package you’ll find all latest patches available from Rob, from his current development tree.

To start using XBMC with the Ubuntu LEB image at your Pandaboard, you just need to install the xbmc package, with $ sudo apt-get install xbmc. For best user experience, please use the XBMC session available at LightDM (just log-out the default session and select XBMC instead). This will work a lot better because then there will be no other window manager or compositor taking extra resources from your board.

We also hope to deliver a set-top box image by the end of the current cycle (12.01), that will have XBMC installed by default. Please check the blueprint https://blueprints.launchpad.net/linaro-ubuntu/+spec/create-a-set-top-box-leb-image if you want to follow the progress of it.

Bugs and Issues

Unfortunately not everything is working perfectly at the moment, and issues with the Gstreamer and hw video decode support on Pandaboard are expected. The most annoying one that’s currently affecting XBMC is the issues with seek, as sometimes the video goes faster than the audio, and then it stops for a while until it’s in sync again. We hope to get this fixed soon, but that depends a bit of how much time Rob can spend on it.

In case of any other bug while trying to get video decode to work on your Pandaboard, don’t hesitate to open a bug at https://bugs.launchpad.net/linaro-ubuntu/+filebug or ping aviksil, robclark or rsalveti at #linaro on freenode.

Cheers!

Update: Check bug https://bugs.launchpad.net/linaro-ubuntu/+bug/915456 for the video hanging issue. Without polling XBMC should now play most videos just fine.

Update 2: XBMC-ready image already available at http://snapshots.linaro.org/oneiric/linaro-o-linarotv-xbmc/, just be sure to flash with http://snapshots.linaro.org/oneiric/lt-panda-x11-base-oneiric/.

Update 3: There’s a mem leak at the gst decode codec, check bug https://bugs.launchpad.net/ubuntu-omap4-extras-multimedia/+bug/915768 for progress on that.

bembel 10:54 on January 8, 2012

Cool.. thanks. I have tested it yesterday, but sadly it didn’t works on my pandaboard. I got many graphical errors in ubuntu (black blocks, vertical and horizontal lines etc.) and the video playback fps were nearly the same like in ubuntu 11.10 with the multimedia packages and a self compiled xbmc (something about 10-15fps – even with sd video files).
But perhaps I did something wrong, I’ll test it again.
- rsalveti 13:52 on January 8, 2012
  
  That’s weird, which Pandaboard revision do you have? Here I didn’t have any graphical errors at the XBMC interface. Also, did you try running XBMC from the lightdm session (just log-out and select XBMC at the login box). Without any window manager the decode and interface work a lot faster.

Oh sorry, my bad. I did not running xbmc from the xbmc lightDM session. If I do it, xbmc works fine (with the known bugs and issues you describe above). Great work, it is a big improvment 🙂
The graphical errors are still there, but not at the xbmc interface. The errors are at the ubuntu desktop when I use the default lightDM session. It is weird, it looks like the errors you get if your graphic card has a hardware failure…
The revision of my pandaboard is A3.

  One workaround is to use the Unity 2D interface, which is a bit more stable, and with less rendering issues (log-out and select Ubuntu 2D at lightdm).

I’m trying a fresh ‘install’.. As I’m currently running 3.1.5 (clone of kernel-tilt, branch tilt-linux-linaro-3.1 up to date).. I’m going to hate running rootfs off the sd (again)..

In better news, mdadm/raid0 works perfectly. 🙂 Doesn’t improve speed much (64k chunk is worse than 128k, opposite of what I would expect)… but I just had to test it. musb and usb have separate channels, correct?
Edward S. 18:09 on January 9, 2012

Ok, I tried a new install.. rootfs on usb disk…. totem in unity was awful (as expected).. XBMC is less prone to be glitchy.. But there seems to be tearing and the occasional frame drop.. about every second or two.. 99% of tearing is a single line dividing the screen… It looks to be exactly in the middle.. 960 pixels? ‘Glitchiness’ does not seem to scale on codec/decoder complexity.. Some low res xvid videos were worse than high profile 720p x264 matroska.. I suppose this isn’t really a big deal, the important thing is that hw decode is actually being utilized..

One thing I gotta say.. I despise using unity on my laptop… using it on the pandaboard is nothing short of torture.. Why use it? Is it just a matter of sticking with what ubuntu uses or did someone actually say.. “Yeah, unity will work great with this”?
- rsalveti 19:55 on January 9, 2012
  
  Yeah, our major goal here was to actually have a valid solution where we could get at the pieces working together. There are quite a few issues with hw decode, but TI said they will be releasing newer components soon, so I’m hoping it’ll improve quite a bit.
  
  Unity is broken this way because of Compiz, that still has quite a few issues with GLES. The goal was to enable the same user experience, but unfortunately there are still a lot to do at Compiz side. My suggestion would be to stick with Unity 2D until 3D is working properly (may take a while).
Edward S. 20:41 on January 9, 2012

Thanks for the reply. Even on a hexacore w/16gb of ram Unity is irritating. Perhaps MATE (gnome 2 backport) will be available for arm.. But thats a different issue entirely.. Whats strange for me is the errors I’m having with ducati on my current working setup.. Going back to a single usb disk rootfs and 1.2ghz clock, I realized how much faster this dual usb (mdraid) rootfs and 1.5ghz clock is.. I’d say the 1.5ghz helps out the most. I have a little heatsink (graphics card memory sink) sitting atop the 4460 to help with excess heat.

when the omapdrm_pvr module is built, kernel_dir pointing to the correct place (again, clone of kernel-tilt, branch tilt-linux-linaro-3.1), it is a whopping 40KB smaller than the module for 3.1.1-6…. It crashes upon loading, yet appears to be functional and listed in the output of lsmod.. gstreamer-properties works fine for testing pvrvideosink..Still, I think that may be my problem with my ‘customized’ rootfs.. I think I have smartreflex turned off, but that may be the only difference in my config (besides additions). I’ll test out the custom kernel on the default rootfs.. can’t test out default kernel on custom rootfs due to lack of raid0 support.

Finally, when the time comes – will TI/Imagination be ready to supply proprietary blobs for armhf arch? I wonder how much work will need to be done to cross everything over?

  The config we’re using at the lt-omap kernel package: http://git.linaro.org/gitweb?p=people/jcrigby/linux-lt.git;a=blob;f=debian.linaro/config/config.common.ubuntu , if you want to compare with yours.
  
  Ubuntu ARMHF is already available based on Precise, and I know TI is already working with Canonical/Linaro to also make the driver available for ARMHF, so I expect it to be out until the end of this month.

im confused why the dependency on Gstreamer as your only HS playback option when ARM ffmpeg/ffplay is available and waiting for all the patches including NEON SIMD optimisations you and the other vendors might supply/pass to them in their dev IRC/message board.
- rsalveti 12:38 on January 13, 2012
  
  We are also enabling NEON optimizations on ffmpeg/libav and such, it’s just that Gstreamer is a requirement if you want to use hw decode support on OMAP 4, using ducati, gst-ducati and the pvrvideosink (for texture streaming and such).

Hi I am currently trying to have video and 3D hardware acceleration on my pandaboard. I am not using ubuntu but I am working directly with source codes.

For the moment, I have compiled everything required to have a X window system (including u-boot, kernel, omafb driver, a basic window manager). Everything is working fine.

However I would like to go a step further and have the hardware acceleration for 3D and video. I have retrieved the pvr dkms modules (1.7.10.0) from: https://launchpad.net/~tiomap-dev/+archive/release But the code is not compiling with the kernel I am currently using: http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap.git;a=tree

I am looking for a valid linux kernel source tree with the required patches to compile the SGX kernel module. Could you please spare the good uri where I could find this ?

If you could, it would be great to give the main git repositories for the main “pandaboard software” like:
– kernel with required patches
– pvr-omap4-dkms and pvr-omap4 (i know pvr-omap4 is closed source, but where can I download the latest version ?)
– gstreamer and gst-ducati
– xf86-video-omapfb
– any other things I am not aware yet 🙂

I am spending more time to look for source codes, than to actually work on my project 😦

Thanks in advance

    Hi
    
    First of all, thanks a lot for the links 🙂
    
    I have retrieved the sources of everything (u-boot, kernel, pvr-omap4-kernel-module, pvr-omap4-libs)
    
    But when I boot the kernel, I get many debug messages from the DSS system. (http://www.heypasteit.com/clip/076F). It seems that the kernel failed to set “PHY power mode” to 1 which seems to be required for display initialization.
    Anyway the consequence is quite simple: nothing is displayed on the screen. I can only get access via minicom.
    
    I have used the same home made config file to compile other kernel for the pandaboard and I was able to start xorg (with the omapfb driver). However it might come from this kernel config file, could you share yours ? or do you have another idea for solving the problem ?
    
    Regards
    
    PS: I have retrieved this kernel. It is right one, correct ?
    git clone git://git.linaro.org/landing-teams/working/ti/kernel.git git checkout tilt-linux-linaro-3.1
  - rsalveti 15:24 on January 27, 2012
    
    That’s weird. What’s the resolution the kernel is using at the framebuffer when you’re booting the board? Using ‘omapdss.debug=1 drm.debug=7 loglevel=8’ should probably help you finding what is happening on the driver side. Would probably recommend you to open a bug for this behavior.
- rsalveti 18:14 on January 25, 2012
  
  tilt-linux-linaro-3.1 is the correct tree/branch, I wonder if the config you used was not fully functional. You can grab the config we’re using by extracting the package (/boot/config-) or by checking at https://github.com/jcrigby/packaged-linux-linaro-3.1-ci/blob/lt-omap/debian.linaro/config/config.common.ubuntu (merged tree with tilt + packaging).

    Of course the lib are installed.
    
    By chance do you have any idea ?

  Hi,
  
  I have managed to get the 3D hardware acceleration on my pandaboard and now I am passing to the the second step which is to compile gstreamer with video acceleration.
  
  Among the packages to compile, I have to deal withthe libdce to get gst-openmax running. But I have read in the libdce README file that I have to install HDCICP2. But the indicated URL is no longer valid http://software-dl.ti.com/dsps/dsps_public_sw/codecs/HDVICP2/index_FDS.html.
  
  Do I really need it to get gstreamer running with hardware acceleration or is there another way ? If no, do you know where I can find it.
  
  Best regards

I just loaded up xbmc on my pandaboard es and works like a champ, I even scanned my external drive and populated the video thumbnails. The only issue I really have is when the system is decoding full 1080p bluray MKV files. The files play fairly smooth with minor hitches in between but the frame rate does drop to half of what it should be. 720p MKV’s play almost perfect. I think there are some issues with the decoders for MKV/MP4 because other full 1080/720 files that are AVI play flawlessly. When I get off work today I will upload a video with my findings on youtube. I get irritated by seeing the blank CPU field because on my first LEB install I was able to install cpufreq and modprobed and the omap2plus driver was there and recognized, but this go around that was not so, I am not a programmer or anything like that I am actually a buyer with the interest in embedded linux and have transitioned from using the beagle board to the panda.
- rsalveti 14:48 on January 18, 2012
  
  Are you using the poll workaround described at https://bugs.launchpad.net/linaro-ubuntu/+bug/915456 when testing 1080p videos?
  Guess for the cpu field would be something we could also check at the xbmc code. Can you spend some time opening both bugs against https://bugs.launchpad.net/linaro-ubuntu/+filebug ?
  - chris 04:30 on January 25, 2012
    
    So I finally got time to play with my board and instead of using the poll method I went a different rout and set the cpu cores to their maximum frequency since for some reason the system always starts with the cores lock on the minimum 350mhz…. once I switched this I am able to play the higher definition video withought the atrocious frame drops, however not perfect but certainly watchable at appropriate frame rates but sometimes frames tend to go on the high side 40’s while the audio adjust to the video, I think I will lower the voltage to 800mhz and if given enough time I think the video will finish buffering and settle jus have not given it enoughhh time.

Hi,
I am following this project with great interest. Thanks to all who are contributing.

I installed the linarotv image 20120114-2 and hwpack_linaro-lt-panda-x11-base_20120106-1 on a pandaboard ES, then installed ubuntu-omap4-extras-multimedia and started that with a connection of the HDMI to a Yamaha RX-V and from there to a 1080p plasma.
The resulting screen resolution was only 720×576@50 (the default for SDTV here) so I am guessing the EDID the Yamaha is sending out is somewhat problematic (the same installation starts with 1920×1080 just fine when connected to a cheap 1080 LCD monitor and other devices like my Blu-Ray player can do 1080p through the Yamaha). But that is not my main concern now. I will keep researching on this but maybe you can give me a hint in what direction I should read up on how to bypass the EDID and force the available screen resolutions similar to how I did it with my nvidia/vdpau based xbmc in its xorg.conf?

I then played around with the audio settings in xbmc and set it to
Audio output: HDMI
Speaker Configuration: 5.1
Audio output device: Defaults (ALSA)
Passthrough output devive: hdmi (ALSA)
(all other settings did no work)

When passthrough of Dolby and DTS is enabled, the sound from videos with AC3 does not work.
When passthrough is disabled, only two audio channels are sent to the Yamaha even from 5.1 source material (the RX it has little symbols in its display that show which audio channels are being used).
Speaker test videos sound correct for front left, front right and center (the latter only because the pro-logic decoder puts mono sound onto the center) but rear sound is played with low volume on the front speakers.

I now wonder if I just configured xbmc wrong or if this is also an EDID interpretation problem (the Yamaha announces its audio capabilities) or if I could fix it in the alsa configuration.

I guess it would be a great feature to have some means to just tell the system what the connected audio and video hardware is capable of and thus get rid of EDID problems and the like.
- rsalveti 19:28 on January 19, 2012
  
  For EDID, I would not be surprised to see a bug at your monitor or even at the HDMI/DRM driver for OMAP. If you add omapdss.debug=1 drm.debug=7 to the kernel cmd line you should probably see what is happening at the kernel side. Another option would be to get the EDID and parse it to understand what the monitor is providing.
  
  In case the driver is wrong, please open a bug at http://launchpad.net/linaro-ubuntu putting your logs, or just go to #linaro @ freenode, and look for rsalveti or robclark (who created the drm driver).
  
  Now for sound, I’d recommend you to update your image (apt-get update/dist-upgrade) to make sure you’re using the last packages available first. Then if it’s still not working properly, would be good to understand if the issue is at Alsa, Alsa UCM or Pulse, as any could be messing up with your sistem. Please open a bug if it still doesn’t work for you.
  - Eckhard 18:16 on January 20, 2012
    
    I opened the bugs like you suggested.
    
    While checking the EDIDs I noticed that while 1080p50 and 1080p60 are being sent by the Yamaha, the AVR is embezzling some other resolutions the TV is reporting in its EDID to the AVR (1080p59.94, 1080p23.98). So I think it would still be good to have a documented way to manually add modes so that xbmc can use them (when connected directly to the plasma xbmc is also offering only 50p and 60p but not 59.94p and 23.98p).
    I will keep trying to figure out how to override or extend the available modes but any hint as to how to go about it are welcome.
- rsalveti 18:17 on January 25, 2012
  
  Thanks for opening the bugs.
  
  You could try to force the mode at the DRM driver (check http://nouveau.freedesktop.org/wiki/KernelModeSetting), but the HDMI driver will still limit your options. One thing you could do is to try calculating the timings from your monitor, or hacking the DRM driver to support interlaced mode and others.
  
  Hope to have these bugs fixed soon.

What is best practices for setting up wireless networking under this image? Should I switch to a terminal (Ctrl-Alt-F2) and setup wpa_supplicant details in the /etc/network/interfaces file? If so…do I need to disable NetworkManager etc.? Also…anyone else have problems switching back to XBMC via Ctrl-Alt-F7 after working in a terminal?

  You just need to configure your network/interfaces correctly and network manager will not handle your device. Check at http://blog.nelhage.com/2008/08/using-wpa_supplicant-on-debianubuntu/.

    Thanks. My problem had to do with the new way that wpa_supplicant gets started up. I had to edit the invocation via /usr/share/dbus-1/system-services/fi…wpa_supplicant… files and add to the invocation “-i wlan0 -c /etc/wpa_supplicant.conf”. That, in addition to the changes to /etc/network/interfaces and new /etc/wpa_supplicant.conf file, seemed to get it up. Something tells me that with the newer DBUS/NetworkManager world I probably went about this the hard way. Should I have not edited the /usr/share/dbus-1 files and instead added some commands to the interface file to accomplish the same thing?

Works Great. I’m actually using the ubuntu oneirics generic kernel with Linaro overlay ppa since the linaro kernel doesn’t seem to have twofish and xts crypto modules which I need to encrypt my external HDD.

Anyway, one big issue I saw is that I can’t play vob files (DVD Backups with mplayer dumfile). 1/3 of the right screen is just blur nonsense and the video is scaled wrongI guess this is somehow related to gstreamer since I can watch the same files with the the official xbmc11. Is there a way to let ffmpeg play SD and gstreamer HD in xbmc?

I have installed the setup box image from march/11 but i am having some issues, video playback works almost perfect but it seems that randomly it pauses for half a second and then accelerates to catch up. The other issue is that i can’t get xbmcto run in 1080 as every time i change the setting inside xbmc it freezes and then logouts. Any help would be really appreciated.

  it seems drm polling turns back on everytime i reboot the system even if i manually turn it off

    I seem to have solved the fact that disabling polling didn’t work, after checking its parameter it seems that polling parameter resets itself to on every time it turns on. I have fixed it by adding to rc.local (echo 0 > /sys/module/drm_kms_helper/parameters/poll), now every time the system starts it disables polling. I still have issues setting xbmc to 1080 if anyone can help.

I am trying to get xbmc installed on my Droid Bionic (which has the TI-OMAP4 SoC).

I have a full Ubuntu distro installed, and I can play videos with VLC with no problem.

But, I am new to Ubuntu – I am coming from the Red Hat world by way of Mandriva/Mageia, so the who concept of ppas is new to me – I am used to a more central integration of packages, rather than having to seek out a bunch of repositories from lots of different devs. I think my distro (which is based off of the default Motorola webtop) is Maverick. So even how I go about upgrading to Oneric is a bit baffling to me.

But in principle, shouldn’t this work on my Bionic? It has a 1GHz dual core processor and is definitely capable of playing 1080p content?

Any help or comments would be very much appreciated!

If you want to know the crystal clear details it is better to view just about any
online store web sites explaining the actual product or service
information using elements. Perhaps the main reason behind this though is that you have developed
a dependence on food. Having said that, the study has shown that just about anything that
can maximize the metabolism, also can raise the weight reduction even if the human being is just resting.
