Hey, can someone explain to me what's going on here? Why is this download failing, why is it not working for me?

I believe it's because on a L3 CDM you are capped at 720p for that service. Try -q 720, it should then work. For 1080p you need a PlayReady device to get the key.

How do I get a PlayReady device? Or just some way of downloading this in 1080p? Has anyone managed to successfully download this in 1080p using Unshackle?Originally Posted by F1sav28

stabbedbybrick has fixed and updated CWTV. I should have got off my duff and raised the issue over at his website as that is what we are to do when we have a problem with a service and we know it is not just something to do with our setup or technique. It is good to see it is fixed.

Has anyone else recent had errors in muxing/merging ec3 audio with CBC stream downloads?
The video file when played locally on vlc plays fine, except when it gets to roughly 35mins, 30 seconds. There is a slight jump in video/audio play. Not a big deal playing locally.
JellyFin and Plex just plain stop and will not continue.
Downloading - https://gem.cbc.ca/saint-pierre s02e05 for example:
I get a series of errors when trying to get ec3 audio:Code:uv run unshackle dl -q 720 -a ec3 -w s02e05 cbc https://gem.cbc.ca/saint-pierre

Everything that comes into play with unshackle is up to date on my side.
I have tried all combos with the video and ec3 audio. DL audio separate, and merge with ffmpeg and result is the same as described above. -

You had gotten no output errors like I showed? I assume not, you would have said.

When it comes to "Diff'rent Strokes" on Tubi TV there are a few episodes missing and it looks like these are edited episodes as most of them are about 22 minutes and they should be around 25 minutes. On top of that there is a slight combing issue with the videos. They have released all the seasons finally on DVD so that is probably the best way to go.

I am sure I have something out of place, or doing something wrong with the TVNZ service. I used to be able to download no issues. Now I get errors no matter what I change in my unshackle.yaml, what downloader I use aria2c or n_m3u8dl_re. Both seem to have similar but different errors.
If I tryhttps://www.tvnz.co.nz/shows/lord-of-the-flies
Is this something out of place? I have looked and followed the trace, but I cannot figure this out at all.

I tried the same episode with 5ch audio and got the same warning messages as you when unshackle was doing the merging. When playing the output, at around the same mark, while mpv did output messages indicating corruption, it did continue to play the audio seamlessly.Originally Posted by ehurdler
I am not familiar with Plex, but if you happen to be using a Jellyfin client on Android TV, consider a more robust client. Wholphin, for example, an open-source client, can use mpv for playback. I didn't try it myself, admittedly, but from my experiences with mpv on a PC, it probably won't stop...
It's a known issue, apparently, and mentioned in the help for the CBC service:Anyone else have this issue, or know a fix?
The "publicly" available release for that episode from the CBC with 5ch audio also exhibits corruption around the same time. Maybe the CBC just serves corrupt 5ch audio sometimes...Code:C:\Users\Me\unshackle>unshackle dl CBC -? [trimmed] Notes: - Some audio tracks contain invalid data, causing warning messages from mkvmerge during muxing These can be ignored.
Works for me (over a slow proxy), N_m3u8DL-RE as downloader:Originally Posted by ehurdler
From your error messages, is C:\Users\*MyUserName*\bin\shaka-packager.EXE actually Shaka Packager? That is, not something like mp4decrypt.exe renamed to shaka-packager.EXE.
