Split input video into several identical outputs.
The filter accepts a single parameter which specifies the number of outputs. If unspecified, it defaults to 2.
For example
ffmpeg -i INPUT -filter_complex split=5 OUTPUT
will create 5 copies of the input video.
For example:
[in] split [splitout1][splitout2]; [splitout1] crop=100:100:0:0 [cropout]; [splitout2] pad=200:200:100:100 [padout];
will create two separate outputs from the same input, one cropped and one padded.
