Hi,
I am using FFmpeg to generate mpegts segments. FFmpeg has memory leaks,
see the valgrind output in the attachment.
Command line to reproduce:
> valgrind --tool=memcheck --leak-check=full ./ffmpeg_g -f decklink -i
'DeckLink Mini Recorder at 14' -map 0 -acodec libvo_aacenc -vcodec libx264
-pix_fmt yuv420p -vprofile baseline -q 2 -r 25 -g 25 -dn -f
stream_segment -segment_format mpegts -segment_time 10
/dev/shm/capture/libav-%010d.ts
I have read the source code of libavformat/segment.c and make a patch
which is attached as well to fix it.
