[Libav-user] how to config multi inputs filter graph

[Jesse Liu]

Thanks your reply, Paul. It seems the filtering_video.c just show how to init simple filter graph, the problem is that I don’t know how to configure multiple buffersrc and connect them to graph like filter_complex. I’m a newbie in ffmpeg, really hope there is a example about how to config complex filter graph. THANKS!
