[FFmpeg-user] Help me with multi input in a video

[Emre Karataşoğlu]

Thank you Roger for your interest .
If I use
----
ffmpeg.exe -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2,
pad=2*iw:ih [left]; movie=a.avi, scale=iw/4:ih/4 [right]; [left][right]
overlay=main_w/2:0 [out]"  -f flv rtmp://localhost/live/firstTwo

---
There is no problem , I take what I need .
But I wanna use

---
ffmpeg.exe -i rtmp://localhost/live/me -vf "[in] scale=iw/2:ih/2,
pad=2*iw:ih [left]; movie= rtmp://localhost/live/me1, scale=iw/4:ih/4
[right]; [left][right] overlay=main_w/2:0 [out]"  -f flv
rtmp://localhost/live/firstTwo

--
In this case ffmpeg throw ex. I think cause of ':' I try to escape this
charecter with backslash. But noway.
ıt said 'missing key or no key/value  seperator found after key
//localhost...'
Error movie parameter args with rtmp://...
I presume movie parameter waits for .mp4 .avi etc. like amovie wait for
.mp3 etc.
---- Secondly yes . I want 2 x 2 4 video .
Now I can do it with the code above in 2 proccess.
1.step
I join side by side each of pair
then I have two 1x1 videos

then I join again 1 x 1 video top and bottom .
after that I get 2x2 video .
in this case it's not problem but
in 4x4 video ? what the hell am I doıng ?
