[FFmpeg-user] avformat_free_context function is not able to free the stuff that was cached by avcodec_encode_video2

[Harald Jordan]

Hm, that is hard to tell, the way ffmpeg and my code works is different: i
have a dll thats runtime stays alive for multiple independent transcoding
runs, ffmpeg ends it's runtime everytime a file is ready transcoded. 
So I assume even if there is a problem in ffmpeg base application, it is not
worth the effort of debugging? ;-)

All the best,
Harry

Does this happen with the ffmpeg command-line tool too? It is regularly
tested for memory leaks. If there is none in the command-line tool, maybe
something is wrong in your program.
