🐞 Fails with "Error opening input file ./output.mp4." (unknown codec / unsupported type)

[spxak1]

This tools looks very promising, but I can't get it to work:

I get:

in#0 @ 0x55c70e4d5500] Error opening input: No such file or directory
Error opening input file ./output.mp4.
Error opening input files: No such file or directory
thread 'main' panicked at src/commanders/chapterer.rs:55:59:
called `Result::unwrap()` on an `Err` value: Os { code: 2, kind: NotFound, message: "No such file or directory" }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Many thanks.

Hello @spxak1 👋 thanks for your request! 🙌

I can't reproduce this with mp4 files but with mov files, will take a closer look soon 🔧✨

Seems to be a bit more complicated, the important lines are:

[concat @ 0x561eeb743380] Could not find codec parameters for stream 2 (Unknown: none): unknown codec

...

[out#0/mp4 @ 0x561eeb791e00] Cannot map stream #0:2 - unsupported type.
[out#0/mp4 @ 0x561eeb791e00] If you want unsupported types ignored instead of failing, please use the -ignore_unknown option

Somehow they are not supported and -ignore_unknown would only create corrupted output.

For me it worked after converting the input videos with ffmpegs basic functionality:

mkdir new
ffmpeg -i 1.mp4 new/1.mp4
ffmpeg -i 2.mp4 new/2.mp4
vidmerger new

Could add a fallback solution which converts the input videos when it detects that error and then merges them.
