Hi all,
when I tried to encode large dumped dvb stream (mpeg2) to mpeg4, mencoder crashed
the crash occured always when 80% was done
I tried also encode other dumped dvb streams and that was ok
ocko.ps - dumped dvb stream (1.7GB)
mencoder -oac copy -ovc lavc -lavcopts vcodec=mpeg4 -o ocko.avi ocko.ps
