Is there any way to split mp4 in 2 files in Golang?
Hi, you want to produce fmp4 segments or split into multiple "progressive" mp4s? one of these examples might be useful: https://github.com/Eyevinn/mp4ff/tree/master/cmd/mp4ff-crop https://github.com/Eyevinn/mp4ff/tree/master/examples/segmenter

mp4ff - beyond MP4 boxes
Part 30 of the MPEG-4 standard describes how TTML and WebVTT subtitles shall be carried in MP4 files. The approaches are very different. For TTML, the original XML structure is used, and there is typically a single sample per segment. That sample is a complete TTML XML document with internal time stamps. Beyond text, it can also provide image subtitles and carry such images as subsamples. The codecs attribute for such a file is stpp, and there is an [stpp] box that should be included in the track sample descriptor. mp4ff supports all relevant boxes.

Ffmpeg wrapper
I have used the ffmpeg-go in the past and found it quite nice. My usecase was decoding the video to raw frames and then directly processing the raw frame bytes further in Go.

Is there any way to split mp4 in 2 files in Golang?
Obviously this is tongue in cheek. You could probably do this in Go but I'd recommend just using ffmpeg. There are bindings to ffmpeg in Go but I doubt it's going to be easier than writing it directly in C, unless you aren't proficient with C.

created a CLI tool [reddit-dl] to help download reddit videos/images/gif
For merging, yes, it's a bit problematic. From what I saw in the community the use of ffmpeg is often made, but not in raw (exec.Cmd). I would recommend the use of https://github.com/u2takey/ffmpeg-go module which provides a convenient API, permitting to defer the load of ffmpeg CLI API. I never used it but it seems a good solution.

run exec.Command
I used u2takey/ffmpeg-go to merge two streams (audio and video) in a project, and worked just fine.
