N_m3u8DL-RE always muxing error with at least one resolution

[imayus]

23:47:31.570 ERROR: Mux failed
23:47:31.571 ERROR: Failed

While downloading mpd and decrypting with N_m3u8DL-RE, I'm always getting muxing failed error (both with mkvmerge & ffmpeg) with at least one resolutions.

Means, for some files I'm getting muxing failed error with 1080 version, sometimes 720 and sometimes with other version. What's causing this? Can you please help?

BTW, I'm using N_m3u8DL-RE version 0.2.1, it's prompting New version v0.3.0-beta

This is the MPD & KEYS:

Try adding

--use-shaka-packager

[imayus]

N_m3u8DL-RE "{mpd_url}" --key "{key}" -sv res="{r}*":for=best -sa best --use-shaka-packager --save-name "{output_name}" -M format=mkv:muxer=mkvmerge

Already using this

It fails only for the 1080p with the highest bitrate. No idea why though. Tried decrypting manually using mp4decrypt and shaka and they both fail. Shaka can't even parse it

As alternative, you can go for the next 1080p with lower bitrate.

there's HLS version with higher 2985kbps

You need aes key for that though since it doesn't use widevine

yes but how do u get the key for this m3u8 ?

anyone has any solutions for the mpd higher bitrate video ?

How did you get this HLS URL?

Can MPD keys decrypt it?

But what to do when it happens with other quality like 720, 480, etc. Because most of times I have noticed they don't have multiple bitrates for all the qualities.

Can you give some mpd urls examples with their decryption keys included for those qualities as well? Curious how they look

Try the 576 version of this:

Interestingly enough, shaka player can decrypt and play 576 with no problem locally, so the key isn't the problem

It's just that shaka packager can't parse it. I suppose you could report this issue in the packager repo and hope it gets fixed in the next version
