Odroid C2 mpeg4 hardware accelleration

  • 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.

  • 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
    ...

  • smp thanks.

    Here is the video output

  • 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.
