5 months ago I probably can't help much here. Two suggestions:
-
The key might be incorrect. I suspect that the stream duration metadata is not encrypted, so ffprobe showing valid information for duration and codecs is not a valid indication that the key is correct. I also don't know of any method to determine whether a decryption key is valid other than checking whether a stream can be decoded/played.
-
You might try with another muxing application, such as mkvmerge, with a different container format like mkv. Or check that you have the latest ffmpeg version. Some streams don't mux/play with certain muxers and work with others.

Hi there! Absolutely love this tool, thank you so much. (also if there is somewhere I can donate some $ as a thank you, let me know).
I'm having an issue with some Clearkey encoded media. I believe I have the correct decryption key, and everything works as expected (including seeing the correct video), but there is no audio. I did a bunch of debugging, and the audio that is downloaded seems right (ffprobe shows the right length) but it's just... wrong. When I try to convert it using ffmpeg there are just a ton of random errors. The audio is just fine when I play off the source website in my browser.
dash-mpd-cli shows "ffmpeg stderr: [aac @ 0x137604c70] channel element 2.9 is not allocated" when it tries to mux. ffprobe shows the same error when I save just the audio and try to use that command on it
Have you seen anything like this before? Thanks again!
