Re: [FFmpeg-user] Conference video-like filtergraph eating memory

Hi Carl, I'm using the latter, the ffmpeg CLI. The entire command is: ffmpeg \ -i DV_b2.mp4 \ -i SCREEN_ba.mp4 \ -i SCREEN_d9.mp4 \ -i SCREEN_6d.mp4 \ -i SCREEN_bb.mp4 \ -threads 1 \ -filter_complex 'filter here' \ -map '[cc8]' \ -c:v ffv1 \ out.avi I've also tried x264 in the matroska and mp4

Paul, Okay, sounds like something I might take a stab at. I'm looking through the devel list now for anything related. If you have a few minutes could you link or refer me to some relevant material on the new APIs? I'd try to reach out to the concat maintainer too but I don't see anyone listed
