avcodec/v4l2_context: send start decode command after dynamic resolution change event
Fixes decoding of sample https://streams.videolan.org/ffmpeg/incoming/720p60.mp4
on RPi4 after kernel driver commit:
staging: bcm2835-codec: Format changed should trigger drain
Reference:
linux/Documentation/userspace-api/media/v4l/dev-decoder.rst
"A source change triggers an implicit decoder drain, similar to the
explicit Drain sequence. The decoder is stopped after it completes.
The decoding process must be resumed with either a pair of calls to
VIDIOC_STREAMOFF and VIDIOC_STREAMON on the CAPTURE queue, or a call to
VIDIOC_DECODER_CMD with the V4L2_DEC_CMD_START command."
