Hi How should I check whether or not a given profile and level is supported by a stateful decoder? Chrome uses VIDIOC_QUERYMENU to test whether a given profile is supported by, say, V4L2_CID_MPEG_VIDEO_H264_PROFILE. Is this "correct"? Certainly a few decoders seem to support this usage (qcom/venus, mediatek and possibly some others). The documentation currently suggests that V4L2_CID_MPEG_VIDEO_H264_PROFILE is only an encoder control. Should the documentation be extended to cover decoder use too? Many thanks John Cox
