MMAL on Raspberry Pi 3 - Comskip

ross232 · February 6, 2018 at 2:25 AM

Hello,

Apologies if this has been asked before. I'm using Comskip on my Raspberry Pi 3 running LibreELEC.

I'd like to use it's hardware decode feature which uses the mmal decoders (mpeg2_mmal, h264_mmal, mpeg4_mmal and vc1_mmal). It doesn't look like LibreElec's ffmpeg (in 8.2.2) has been compiled with support for these.

I'm happy to submit a pull request with these changes to the ffmpeg package - just wondering what caveats there are to this?

These are the parameters required:

--enable-mmal --enable-decoder=mpeg2_mmal --enable-decoder=mpeg4_mmal --enable-decoder=h264_mmal --enable-decoder=vc1_mmal --enable-omx-rpi --enable-encoder=h264_omx

Thanks,

Ross.

I would be also interested in using comskip with hardware decoding on rpi.

The ffmpegx package provides ffmpeg with added features, in particular these.

ffmpegx ships with the Emby addon (Emby adds ffmpegx and ffprobex in PATH).

Feel free to add and test more RPi features.

If ffmpegx/ffprobex have other purposes than Emby, we could ship them as a standalone tools addon.
