avcodec/h264dec: Handle non-recovered frames when draining
When starting on a SEI recovery point close enough to the end of the stream that draining starts before the recovery point's frame is output, there can be non-recovered frames in the delayed picture buffer that would currently cause the decoder to fail to output a frame. This commit skips such frames and outputs the first recovered frame, if there exists one. Signed-off-by: arch1t3cht <arch1t3cht@gmail.com> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
