For a thousand minutes I try to find a way that stream multiple video and combine them into a one output . I wanna do that with ffmpeg or xuggler with ffmpeg cmd. VirtualDub and avis couldn't meet my needs. Actually I couldn't find a way stream in avis . I can only make 4 8 16 videos in a screen on virtualdub but they are local videos and not my issue .

>cd c:\f\bin

ffmpeg -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=other stream, scale=iw/4:ih/4 [right]; [left][right] overlay=main_w/2:0 [out]" -b:v 768k output

anyway join two stream side by side , but I want more . Is it possible with ffmpeg ? Also I cant use the program like spycam ,vlc etc . Don't say to me vlc , console vlc can easily do it .

FAQ for ffmpeg includes instructions for concatenation of video. Pay close attention to instructions in section 3.14.3 because if you understand how to demux audio from video and to then convert each track to raw stream, the streams can simply be concatenated.
