M3U8 to MP4 broken

[Chungmire]

.m3u8 files which I can convert with FFmpeg from the command line cannot be converted here. I'll add that they're from twitter and I actually had to prepend https://video.twimg.com before each link in the m3u8 file itself since it wouldn't work otherwise, but after that it works.

Example Link: https://video.twimg.com/dm_video/1764737084227534848/pl/avc1/720x1280/NpkjnUNEEYnrPQd3FtKKlbt0iRjzhtGqWnrknkvYjDE.m3u8?container=cmaf

FFmpeg playground does produce an output file, but it's a 262 byte file with a black screen when the input was a 32 second video. Here's my console log, which admittedly does not look super helpful. I have my own project which does the conversion correctly if you'd like to use my methods. I just don't have the time to go through this codebase and make the changes myself.

I apologize, I haven't had as much time recently. I have a potential fix in the works and a long term plan to rework the site, thanks for using the project
