Concat filter

[Classsic]

Hi, I want to know exactly what this filter works, I need generate a mp4 files from multiple clips, and download as mp4 file.
Right now, we use mapping (sequence). for generete a m3u8 playlist.
Thanks.

This feature is not supported.
Concat filter is very similar to using multiple clips with discontinuity set to false, the added value it provides is that the duration of the mp4s can be different across different sequences.

@erankor, is it still impossible to produce concatenated mp4 from several mp4 chunks?

[erankor]

yes
