[FFmpeg-devel] Valgrind errors

[JULIAN GARDNER]

Whilst tracking down a real peach of a bug in the dvbsubdec.c file, managed to find it, i started up valgrind and got a few warnings which im not sure should be investigated.

command line
valgrind --tool=memcheck --leak-check=full ./ffmpeg_g -ss 5 -i ../Crash3_001.ts -map 0:0 -map 0:1 -map 0:3 -b 1000k -bt 50k -vcodec libx264 -preset faster -acodec libfaac -ac 2 -scodec dvbsub -shard -f mpegts -y a.ts

valgrind output

So do i need to do anything with these, like try and find what is at fault.
