asplit - FFmpeg 3.4.13 / Sources / Multimedia

Split input into several identical outputs.

asplit works with audio input, split with video.

The filter accepts a single parameter which specifies the number of outputs. If unspecified, it defaults to 2.

Examples

Create two separate outputs from the same input:
```
[in] split [out0][out1]
```
To create 3 or more outputs, you need to specify the number of outputs, like in:
```
[in] asplit=3 [out0][out1][out2]
```

Create two separate outputs from the same input, one cropped and one padded:

[in] split [splitout1][splitout2];
[splitout1] crop=100:100:0:0    [cropout];
[splitout2] pad=200:200:100:100 [padout];

Create 5 copies of the input audio with ffmpeg:

ffmpeg -i INPUT -filter_complex asplit=5 OUTPUT
