Chromium V4L2 video decode

[PiotrKrygier]

Hello,

I'm using Yocto Langdale release for IMX8MM. According to this commit message, V4L2 hardware video decoding should be enabled in Chromium with this release:

commit fe0d3587d905a8fa32a9830d177f97c90352fdc5

chromium-ozone-wayland: Add V4L2VDA support on Linux [YOCIMX-6545]

    - support on i.MX 8 series platform.
    - 8MM/8MP/8MQ support h264/hevc/vp8/vp9 hardware decoding.
    - 8QM/8QXP support h264/hevc/vp8 hardware decoding.
    - support seek, playrate change and resolution change.
    - support video acceleration for online media platform such as Youtube, bilibili.

But when I launch Chromium and try to play a h264 video (mp4 file), HW video decoding is disabled and the video stutters. Are there a special configuration that I have to set to enable this feature?

Best regards,

Piotr

Hi,
Thank you for the link however:
1. What you provided is a backport for code, that is already present in langdale release that I'm using. Adding flags mentioned in that post did nothing.
2. I managed to fix the problem. It was fortunately not related to code itself but to the faulty sdcard, that was used to hold the image.
Still, thank you for showing interest in this post and for your time :).

BR,
Pior
