[FFmpeg-devel] [PATCH] libavcodec/tests: Added test for libavcodec/avpacket.c

Thu Nov 3 13:55:40 EET 2016
Function(s) Tested: av_packet_clone().
This test checks if av_packet_clone() can successfully make a copy of an
AVPacket. Compares all data members in AVPacket EXCEPT for "buf" because "buf" is
initialized to NIL in the original AVPacket [to be cloned].
