SlingTV DVR

[ErraticLattice]

I'm trying backup up a ton of TCM intros/outros attached to longer videos on a Sling DVR but I haven't had much success in being able to grab any yet...

I copied the license as fetch and got the key using WidevineFetch:

The closet I've gotten is this, (Unfortunately, this downloads (very) slowly, to the point that I've never actually waited to see if it successfully decrypts or not.):
I've redacted the zip codes and subscriber id.

If I add shaka-packager like so, I get a bunch of red Errors and Decryption Failed notices, while still downloading slowly:

Are they just rate limiting it to make it impossible to get or is there something incorrect in what I've obtained?

try decrypting with mp4decrypt.

look at both red, it not match so you got wrong key

Need auth for your individual DVR, my account can't get this DVR since I don't DVR this show

I would try mp4decrypt but its so slow that it never finishes downloading. iamghost your key also didn't seem to work for me, still slow downloading. I got this key on the same video today: --key 3c575fb71f1040de92d4643ed53ad3a0:5c6e6773399786748 778d980d5f99c5a

I noticed that N_m3u8DL-RE gave me a warning that set the refresh interval to 12 seconds, apparently it's seeing the stream as a live stream. I added the "--live-perform-as-vod=true" flag and it successfully gave me 25 seconds of the video! Decrypted and everything... but only 25seconds. I'm going to try to add a smaller delay, or some other flags to test and see what happens. Other suggestions are welcome.

z1269925944: Thanks for the offer, I feel like I'm closer now, so I'll keep giving it a try for now.

Edit: I also tried the --live-real-time-merge flag, and its indeed downloading/merging it and outputting a playable file after each segment download, but very slow, basically the same amount of time as just watching the movie. :\
