Trying to get vlc for RPi4 to use hardware decoding

[graysky]

I am compiling VLC on Arch ARM aarch64 using a slightly modified recipe from the current distro default to include the following configure options:

Code: Select all

--enable-omxil --enable-omxil-vout --enable-rpi-omxil

. I managed to get the build to work but the resulting binary is not able to playback an x265 test cllip with hardware decoding whereas if I boot to RPiOS, and use their vlc package, the same file plays just fine.

Here is a verbose log: https://gist.github.com/graysky2/43bb24 ... ec9d1fabd7

I don't know what you've done but your VLC installation is badly broken. There shouldn't be any plugin load failure normally.

Thank you for the reply. I booted into RPiOS 11 and as you said, not a single error. Verbose log on RPiOS11 there.

However, I do not believe that the warnings are causing this. If I run the same command on my Arch Linux x86_64 box, the file plays back just fine and the verbose log contains a number of warnings about cannot load modules Verbose log on x86_64.

What do you think?

I don't know if that's the problem, but your installation is badly broken either way. It could very well be another symptom of the same root cause...

Thanks for the feedback. I was finally able to get hardware decoding to work on Arch ARM. Doing so required a patched ffmpeg and modified vlc. My draft PKGBUILDs are here in case others happen upon this thread: https://github.com/graysky2/PKGBUILDs/commits/vlc-rpi
