In order for the encoder to work with gstreamer it needs to have the V4L2_CID_MPEG_VIDEO_VP8_PROFILE ctrl. This patch adds that ctrl with only profile 0 supported. Signed-off-by: Dafna Hirschfeld <redacted>
I confirm starting from GStreamer 1.18 profile (and level for other codecs) are needed. This is to allow proper fallback to other decoders (including software) when the HW is not capable. Acked-by: Nicolas Dufresne <nicolas.dufresne@collabora.com>
