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

Sun Oct 23 09:40:42 EEST 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].
This test also prints out the all the contents of the original and cloned AVPackets.
