[FFmpeg-devel] [PATCH 6/9] avcodec/h264, videotoolbox: return AVERROR_INVALIDDATA when no frames are produced

From: Aman Gupta <aman at tmm1.net>

The only reason videotoolbox wouldn't produce frames is if the data fed
to it was invalid, so returning AVERROR_INVALIDDATA makes sense here.

Further, it means AVERROR_EXTERNAL can be used in further commits to signal
fatal VideoToolbox errors, letting the user know that they need to fallback to
another decoder.
