[FFmpeg-user] side by side videos

[Lorenzo Perone]

Hi Andrey,
thanks for your support!
I had renamed my files after the first test :),
Now to be sure they are right, I've exported again them from the source
cropping and trimming them with MPEG_Streamclip.
If it could be usefull you can download them here;
video1<http://dl.dropbox.com/u/4255917/realtime_test1.mp4>,
video2 <http://dl.dropbox.com/u/4255917/realtime_test2.mp4>

Now they are 642px large and 1050px hight, both of them are 2:41 (mm:ss)
long.
Today I'm working in windows 7 64 bit using FFmpeg git-e0e8c20 64-bit Static
and I've tried this string:

ffmpeg.exe -i realtime_test1.mp4 -vf "[in] scale=642:1050, pad=1284:1050
> [left]; movie=realtime_test2.mp4, scale=642:1050; [left][right]
> overlay=642:0 [out]" Output.mp4


this is the results:

c:\Temp\ffmpeg\bin>ffmpeg.exe -i realtime_test1.mp4 -vf "[in]
> scale=642:1050, pa
> d=1284:1050 [left]; movie=realtime_test2.mp4, scale=642:1050;
> [left][right] over
> lay=642:0 [out]" Output.mp4
