I need to perform 3 operations on a source video (in sequence)
1 resize the source video from 320X 240 to 640X480 (200%)
2 add another video file before
3 add a 3rd video after
In addition I need to combine an audio file with the finished result(3 video files concatentated.
I found a partial solution here, suggesting a way to concatenate 2 video files http://sonnati.wordpress.com/2012/07/02/ffmpeg-the-swiss-army-knife-of-internet-streaming-part-v/
But not sure of the proper syntax to concatenate a 3rd file and also mux an audio file with the finished result. Can anyone help with some suggested settings to try?
