Hi,
I am using ffmpeg version git-2013-06-14-7fff3df and when I use valgrind on a
program using ffmpeg, it displays the following messages :
==19153== 288 bytes in 1 blocks are possibly lost in loss record 112 of

While using the functions : avformat_find_stream_info. I closed the
AvFormatContext using avformat_free_context. avcodec_open2. I closed the
AVCodecContext using avcodec_close.Are they known bugs ? How could I solve it ?
