Describe the bug
I am trying to convert an M3U8 playlist containing .m4s segments into an MP4 file. However, after conversion, I can only retrieve the duration of the media0.m4s file, and the full video is incomplete. I am unsure whether there is an issue with my implementation or if something else is causing the problem. Could you please help me identify the issue?

The expected behavior is to successfully convert the M3U8 playlist containing .m4s segments into a complete MP4 file, similar to how an M3U8 playlist with .ts segments can be converted.

I can see problem in your implementation. this part:
await fileBuffers.entries().forEach(async ([fileName, data]) => {
await this.ffmpeg.writeFile(fileName, data);
});
You cant combine foreach with async. its just wrong.
