I gave an example here: http://lists.ffmpeg.org/pipermail/ffmpeg-user/2016-September/033776.html It seems it doesn't actually work for the fps filter (patch perhaps welcome). Good luck, Moritz P.S.: Syntax for two parameters: Something like echo 'Parsed_scale_1 width 600 height 400' | tools/zmqsend P.P.S.: I recall some patch for actually changing the filter *graph* (i.e. chain(s)) during runtime, don't know where, or what happened. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
