[FFmpeg-user] Memory Leak

[Robert Nagy]

While reading a raw mpeg2video stream the memory usage of each ffmpeg
thread is constantly and slowly increasing.

read_source | ffmpeg -f mpegvideo -probesize 50000000 -i - -f mpeg1video
-bf 0 -b 2M -vf field,scale=w=320:h=180 -threads 1 -an - | write_target

Also even though I have specified threads 1 in htop I can see that the
ffmpeg process has spawned several threads.

Any ideas as to what might be issue?
