- Imported code from omxplayer to revision 9b0793faf2c12f49b743ae3778ece03e31ed1538.
- Now using ffmpeg 2.2.
- Now it can be built using gcc 4.8 using the recent Raspberry Pi Linaro toolchain released in 2014.
- Tested using Qt 5.3.0 beta.
- Tested on the most recent Raspberry Pi firmware: it seems Broadcom has made some changes (fixes?) to the egl_render component. Use the new patch to Qt Multimedia and rebuild. The hack I was forced to add to compensate is no more needed.
Everything seems to keep working correctly, both in 1080p and 720p. Enjoy: https://github.com/carlonluca/pi. Bye! ;-)
For a pi based media player that needs to overlay seek bars and other UI elements would you recommend using your QtMultimedia support or using the custom component ?
ReplyDeleteBoth are available in PiOmxTextures but the technology used is exactly the same, so I don't expect much difference.
DeleteAwesome, I look forward to giving it a try, I'm just getting Qt cross-compiled so we'll see how it goes. Fantastic work you've done.
DeleteI've been trying to get Qt5 to do hardware accelerated h264 video through qml but still no luck.
ReplyDeleteYour solution looks like the cleanest and the fastest. But I'm getting this weird error on the prepare_openmaxil_backend script that has me pinned down. I've confirmed that the compiled Qt5 libraries work with qmlscene on the raspberry pi with 3 images crossfading very smoothly on a spacebar press.
Here is the error I'm having. Hope you can help me out.

At first sight everything looks correct. I have to say I don't use 14.04 and I'm using the 32 bit toolchain, but there seems to be something wrong linking to ffmpeg. This may provide some information: http://stackoverflow.com/questions/3132654/gcc-linker-error-version-node-not-found-for-symbol. If I was you, I'd try to build a sample app using that ffmpeg libs and see if it works. Also, do you have ffmpeg libs in your sysroot?
DeleteThanks Carlon, missed the real error for some reason. By adding --disable-symver to the ffmpeg configure I got it to compile on both Ubuntu 13.10 32bit with 32bit toolchain and Ubuntu 14.04 64bit with the 64bit toolchain. However I couldn't get it to play my test video. Still getting the defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer" error. Must be something with the linking. ldconfig does pick them up but complains about not really being symlinks. Will check it out again this weekend.
DeleteUse the QT_DEBUG_PLUGINS env variable to get information about the issue.
DeleteThanks, that is a handy variable to know about. I'm just starting out with Qt and C++ but I'm really liking what I see so far.
DeleteI was getting some SSL init function errors on my pi because of a version mismatch between my pi and ubuntu install i guess. Disableing ssl in the ffmpeg compile solved that problem.
After copying the libs to /opt and adding it to the linker path ldconfig was complaining about them not being symlinks. Creating them by hand made that go away as well. And now finally I've got it working! There are still some performance issues but I got some improvements by lowering the bit rate of the video. Now all I have to do is get pyqt5 to compile for this qt build and get smooth fades between videos.
Thanks, and if you have any other tips they'd be very much appreciated ;)

DeleteAdd it to the default library paths so that the dynamic linker finds it, as usual.
DeleteHi again,
DeleteThanks for your fast reply. I've deleted my previous comment because I realized that I didn't moved the ffmpeg and the PiOmxTextures folders to the mediaservices folder.
Unfortunately, I haven't achieved making it work yet. Now, the debugger returns me this error:
Got keys from plugin meta data ("org.qt-project.qt.mediaplayer")
QFactoryLoader::QFactoryLoader() checking directory path "/home/pi/pop/mediaservice" ...
loaded library "/usr/local/qt5/plugins/mediaservice/libopenmaxilmediaplayer.so"
QLibraryPrivate::loadPlugin failed on "/usr/local/qt5/plugins/mediaservice/libopenmaxilmediaplayer.so" : "Cannot load library /usr/local/qt5/plugins/mediaservice/libopenmaxilmediaplayer.so: (/usr/local/qt5/plugins/mediaservice/PiOmxTextures/lib/libPiOmxTextures.so.4: undefined symbol: _dl_hwcap)"
defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer
I don't understand what it means with libPiOmxTextures.so.4: undefined symbol: _dl_hwcap.
Do you have any clue?
Just for giving more information, I have already include this lines to the /etc/ld.so.conf.d/libc.conf file to link the libraries:
/usr/local/../plugins/mediaservice/PiOmxTextures/lib
/usr/local/../plugins/mediaservice/ffmpeg/lib
Thanks!
Don't delete questions. Otherwise the discussion makes no sense for others reading. Searching for that error returns an answer I already gave months ago: http://stackoverflow.com/questions/13626726/an-error-building-qt-libraries-for-the-raspberry-pi. But that was at build time. See if that helps somehow.
DeleteHi again,
DeleteTo solve the previous problem, I recompiled all the qt5 ensuring that the cross-compile fix was done correctly. After that, appears this error:
"/usr/local/qt5/plugins/mediaservice/libopenmaxilmediaplayer.so" : "Cannot load library /usr/local/qt5/plugins/mediaservice/libopenmaxilmediaplayer.so: (libPiOmxTextures.so.4: cannot open shared object file: No such file or directory)"
It has been solved (or at least it seems to) by including the ffmpeg and PiOmxTextures path in /etc/ld.so.conf instead of /etc/ld.so.conf.d/*.conf. When I execute the POCPlayer example all was ok just until the file seems to be opened:
VERBOSE: Opening file:///home/pi/a.mp4...
./POCPlayer: symbol lookup error: /usr/local/qt5/plugins/mediaservice/PiOmxTextures/lib/libPiOmxTextures.so.4: undefined symbol: SSL_library_init
I have the latest version of libssl-dev, so I don't now what the problem could be.
Thanks!
I've had the same issue, my sollution was to simply disable openssl when compiling ffmpeg. I didn't need it.
DeleteI know it's not the source of the problem but it got me closer to a working program.
Hi guys!
DeleteFirst of all, thanks to Rio for all the useful tips and Luca for the huge work.
Finally I've make it work with ffmpeg 2.1. As Rio said, disabling symver and openssl it works, but obviously, there is some garbage under the carpet. I will stay on 2.1 for now but I will try to figure out what is happening with the newer version.
If anyone find something useful, it will really appreciated if it's shared with us.
Just for summarazing, here they are the hot points with ffmpeg 2.2:
- Downloading lc_logging.h to the base folder is needed.
- When compiling ffmpeg, --disable-symver and --disable-openssl have to be added to the script.
- For linking the dependencies, you should put the path on /etc/ld.so.conf instead of /etc/ld.so.conf.d/libc.conf. (I don't know why).
- Just for the record, it works in Ubuntu 12.04 and 14.04 (64 bits).
If I've left something, please comment this entry.
Thanks again!
- Yes, you need the LightLogger project.
Delete- No need to disable ssl. Just provide all the dependencies to ffmpeg. Do you have both libssl and libcrypto in your sysroot?
- You can also simply use the LD_LIBRARY_PATH env variable for quick tests.
Hİ guys,
DeleteFirst of all thanks for the tutorials.
my problem is same :defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
How can ı solve that. ı have to recompile all qt5, or can ı handle without recompile.
ı compiled ffmpeg with and without --disable-symver --disable-openssl. but result is same.
Please help,
thanks
You should use the plugins debug function as Luca Carlon mentioned above.
Deleteı use the plugin debugs and result is :
Delete"Cannot load library /usr/local/qt5pi3/plugins/mediaservice/libopenmaxilmediaplayer.so: (/usr/lib/arm-linux-gnueabihf/libstdc++.so.6: version `GLIBCXX_3.4.19' not found (required by /usr/local/qt5pi3/lib/libPiOmxTextures.so.4))"
when ı compile qt5 and carlon pi ı use gcc 4.8 on ubuntu 12.04
ı think have problem with the linkers. but ı am not familiar. can you say how was fix linker problem.
or maybe ı am wrong. can you say waht ı have to do?
thanks..
This means the glibc version that you compiled with is newer than the version that is installed and used on the pi.
DeleteI solved this by using Arch Linux on my pi. Or you can try to compile with a different tool chain (if I understand this cross compiling correctly) that has the same glibc as the distro you are using on the pi.
@ayberk catar: as said you seem to be building with a c++ library which is incompatible with the one found on the device by the dynamic linker. Just provide the correct one so that the linker uses the one linked during build time. Take it from the toolchain and place it on the device. Use LD_LIBRARY_PATH or any other available technique to make the dyn linker use it.
DeleteThanks,Luca and Rİo
Deletethis morning ı solve the problem. your tips very helpfull for me..:)
Hi Carlon, well I try to follow the steps to compile this environment but I'm very lost. You can list the steps to achieve compile everything and make a card?
ReplyDeleteOne of the parts where I lost it, how to get qt5pi folder? I have not been able to find the steps to prepare this directory.
Thank you.
Follow this and the previous posts. You should find all you need to build.
DeleteSure, I've read the previous post but I'm missing something. I have long been trying different things to create a media player but there are always things that I can not find. I keep looking between the previous post and hopefully I can build the development environment.
DeleteIt would be good to do a compilation of the steps to follow in order to realize the construction of this project. It would be very helpful for someone who does not have much knowledge on this topic.
Thank you.

ReplyDeleteHey Luca,
ReplyDeleteJust finished getting this built with Qt 5.3.1 on the January 7, 2014 Raspbian image. I hit most of the same problems the other commenters have encountered, and your advice to them got me through it as well. Works great.
Thanks so much for sharing this - you've really done some amazing things here.
Could you please share your raspberry pi image??? I need this for my university and i am getting crazy!!!
DeleteI'm sorry, I don't have one available anymore. I you have a look at previous articles you may find an old image you can start with.

Hey Luca. Do you know why the quality differs between omxplayer and the QT implementation? Is it QT that "breaks" it? There is a noticeable frame jitter and lack of VSYNC on the video. Any idea? (sorry it this is a duplicated comment as i think google didn't post the previous one)
ReplyDeleteHello, I don't precisely know what you're referring to with "quality" and "jitter", but if with vsync you're referring to the horizontal tearing on the video surface I gave some answers on the blog already about that: I never bothered to investigate much but common cause is concurrency. I remember I implemented a patch for that, but I never completed it and I therefore never tested it either.
DeleteHi Luca,
ReplyDeleteI have "solved" some of my initial problems with the live tv over your library but the tearing problem, so if you don't care, I would like to know what do you think: I guess the problem is that the function onUpdateTriggered() on the videoRendererControl implementation present a frame to the surface when the buffer has been starting changing, so the way to resolve that could be some kind of trigger between the frame and the surface instead the current system based on a QTimer.
What do you thing? Am I totally wrong? Do you thing I there is another approach?
As always, thank you!
Usual approach is commonly a circular buffer.
DeleteMmm, it's really hard to me to find out where the buffer is stored frame by frame... I was trying to use the given fps as QTimer trigger to avoid the tearing, but I guess I should give up (for a while... not enough time right now).
DeleteI just want to let you know how I improve some of the issues:
- Sometime ago I suggest to change the QSize wide * QSize height * 4 for QSize wide * QSize height * 24 on the texture implementation... I was totally wrong. I was thinking that improve the tearing problem but it was caused by other things.
- To improve the weaving effect, I set the DEINTERLACE as AUTO. If I remember well, the OMXVideo.cpp manage to activate it when video size is less than 720*524. This REALLY works.
- When I changed between video sources, video and audio get do not sync correctly... specially when it was HD format. I guess this it was a problem generated by av_clock. I solved this by deleting and relaunching the clock and the players each time the source changed.
- I remove some stop multimedia events from mediaprocessor and openmaxilplayercontrol. There were, in my opinion, too many unnecessary calls to stop(). Also, I started the cleanup function after the last stop on the mediaprocessor while loop. Moreover,some missing Direct connections were added on the texture generation/invalidation, because without them, there was some kind of bad behavior on the OpenMAXILVideoBuffer creation/destruction because sometimes, after change the media source, it first create the videobuffer and after that it was destroyed.
- Finally, I update the OMX lib from popcornmix github.
I really hope you manage to keep working on this lib. I am really impressed for how you manage to make OMX lib work side by side with Qt. And of course, I loved!
Hi Luca
DeleteI would like to know if you implemented these improvements in the repo sources also?
Thanks in advance
What exactly? Tearing is fixed in the no_tearing branch.

DeleteHi Luca, I think I skipped a step. These libraries should install directly from an SD memory Raspbian ?? Sorry for this question but for some time now that I was back to 100% compile a version of Raspbian with everything you've managed to give us, and always came across some problems. Now I do not want to leave anything out and stick with it, to create an installation QT5 + video + browser and create a complete guide for all who wish can have a functional system without much knowledge.
ReplyDeleteAlso I used a lot to learn more and more about these tools.
Well I hope you can guide me a bit.
