Command line video compositor
This is a command line utility for combining video files by placing each video at a specified region in a final composite video.
vidcollage [-cfovh] tile_spec [tile_spec ...]
title_spec := video_filename@WxH+X+Y
-c,--codec FOURCC Output video codec (default: XVID)
-f,--fps fps Output frames per second (default: 30)
-o,--output output Output filename
-v,--verbose Be verbose
-h,--help This help info
Say you have video1.avi and video2.avi, which are both 1920x1080 videos. You can combine them so that they are playing side-by-side with the command:
vidcollage -o twovids.avi video1.avi@960x540+0+0 video2.avi@960x540+960+0
The resulting video will be 1920x540, with video1.avi on the left and video2.avi on the right.
