Stream 0 in this case is the timed ID3 metadata “stream” and non monotonously
increasing dts isn’t an error

I have a number of .ts segments (AES-128 encrypted), .m3u8 chunklist for them
and a key to decrypt them.
My goal is to losslessly remux these .ts segments into one .mp4 file with no

I'm using the following command:
"ffmpeg -allowed_extensions ALL -i chunklist.m3u8 -c copy

Hi, Micael. I tried your command like this:
"ffmpeg -key 5e5852fab5eedf7c6b7a367b1fc140a1 -iv
-i crupto+file:part0.ts part0-decrypted.ts"
and got the following errors:

About the "freshness" of the ffprobe used: I tried with a clean master

Feel free to provide a sample file after testing that the issue is reproducible

I have a strange mpeg2ts file that is giving me problems in our encoding
