Commit Message

Yunfei Dong (董云飞) March 16, 2024, 8:13 a.m. UTC
The supported decoder commands are different for stateless and
stateful architecture. Add stateless decoder commands to fix
the v4l2-compliance test error below.

Codec ioctls:
    VIDIOC_ENCODER_CMD returned -1 (Inappropriate ioctl for device)
    VIDIOC_TRY_ENCODER_CMD returned -1 (Inappropriate ioctl for device)
 test VIDIOC_(TRY_)ENCODER_CMD: OK (Not Supported)
    VIDIOC_G_ENC_INDEX returned -1 (Inappropriate ioctl for device)
 test VIDIOC_G_ENC_INDEX: OK (Not Supported)
    VIDIOC_DECODER_CMD returned -1 (Invalid argument)
    VIDIOC_TRY_DECODER_CMD returned -1 (Invalid argument)
    VIDIOC_TRY_DECODER_CMD returned -1 (Invalid argument)
    fail: v4l2-test-codecs.cpp(126): ret
 test VIDIOC_(TRY_)DECODER_CMD: FAIL

changed with v1:
- remove the static function prefix.
- fix some messages not reasonable.
