[FFmpeg-devel] [PATCH] avformat: Add check for ff_get_extradata

As the potential failure of the memory allocation, the ff_get_extradata() could return error if fails. Therefore, it should be better to deal with the return value of the ff_get_extradata() and return error if fails. Fixes: 2d720069a9 ("avformat: add aix demuxer") Signed-off-by: Jiasheng Jiang --
