- Chromium` will skip decoder with JPEG format support so simplely disable it now.
- Always run vb2_poll for input queue so that chromium doesn't have to listen POLLOUT event, then we can get rid of this patch: https://gitlab.com/cix-linux/cix_opensource/chromium-cix/-/blob/ee8f6/48bff/cix_p1_K6.6_2025Q3_dev/debian/chromium_128.0.6613.84/patches/0001-media-gpu-v4l2-poll-POLLOUT-events-before-source-cha.patch?ref_type=heads
- HEVC is not supported because it is unimplemented by mainline chromium.
Chromium will skil decoders that has JPEG format support. Just disable it then we can have vpu decoder detected by chromium.
…v4l2_poll Chromium does not listen POLLOUT event, but it is necessary to run vb2_poll with input queue for source change. This will let vpu decoding work with mainline chromium without patch.
