[FFmpeg-devel] [PATCH v4 09/14] avcodec/videotoolbox: create avcC even when h264 extradata is missing

From: Aman Gupta <aman at tmm1.net>
Removes the avctx->extradata_size requirement when creating avcC/hvcC, since
avctx->extradata is only used in the esds code path.
This fixes an issue where the VideoToolbox decoder would not work unless
avformat_find_stream_info() was called.
