[FFmpeg-user] How to concatenate multiple mp4 files without re-encoding to an intermediate format

[Rares Pop]

Hi,

I apologise if this has been asked before. Have been googling for hours and couldn't find a solution.

Is it possible to concatenate multiple mp4 files without re-encoding ? How?
(The manual say is possible for containers like webm, mkv, mpg, ts.)

I have tried -i concat: file1|file2, also concatenated the actual files and tried to run ffmpeg with copy on video and audio codecs. No luck.

Thanks for your time,
Rares
