- 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.

@RadxaYuntian Add a new commit: amazingfate@41ae160. This will let us 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/0007-media-gpu-v4l2-increase-bitstream-buffers-to-16.patch?ref_type=heads. With the all 3 patches to cix vpu kernel driver we can use mainline chromium without external patches. |

Chromium will skip decoders that have 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.
