Fixes #10745. Fix segfault on H.264 resolution change.
The H264PreProcessPkt() code was stubbed out for resolution change,
but we were not actually uning the m_h264_parser values. Without this
we wouldn't actually know about changes until after they had occurred
and then we'd be giving ffmpeg improperly sized video frames in the
meantime.

Note: For this to work you will need to disable ffmpeg's multi-threaded
decoding. This is a limitation of the ffmpeg library we're using.
We shouldn't crash if multi-threading is enabled but simply end
playback at the resolution change.
