Hello,
I noticed that the mpeg4 video files are played using software acceleration on my C2.
Does anyone know if there is a specific reason why they are not hw accelerated like h264 or h265?
Thank you
Regards

MPEG-4 is a container format so I'd guess the video is encoded with an unsupported bit-depth like 10-bit H.264 (the H.264 standard and thus all hardware built to follow the standard specifies 8-bit content) and it falls back to software decode.
mediainfo for the file or a Kodi debug log during playback will confirm the hunch.
Thanks chewitt I'll double check it.
I just got this information from the media info during the playback:
Video decoder: ff-mpeg4 (SW)
Pixel format: yuv420p
...: yadif=1:-1:1
Video track: 640x256 px, 2.50 AR, 25.000 FPS

Odd. Can you pastebin a Kodi debug log.
Hi chewitt I just checked the video player settings and the mpeg4 hw acceleration is enabled (by default) only for HD+ content (hw decoder for H265/H264 is always enabled). I read (but unfortunately I can't find the post) that enabling it also for SD can cause issues with the H264 decoder.
Do you think it has been fixed on libreelec 8.2.5.
No idea, but there's so much dumb crap in the 3.14 kernel it's completely possible.
I understand
