Creating direct video link in Objective-C

[cujo30227]

Hi,
I'm experimenting with youtube-dl a bit to implement this in my iOS app. I'm basically reproducing the youtube.py extractor > extract the fmt stream map, identify the mp4 url, read the encrypted signature s, decrypt it using the directions in youtube.py and then adding it to the url link. For some reason, this doesn't work... It works with the non-encrypted signatures, but not with the encrypted one. Using an online Python parser, I confirmed that I have implemented the decryption procedures correctly...

Any suggestions??

You should check you are using the latest algo (it changed yesterday) and if you are following the exact process, it should work.

Sure? I spend 6 hours to set this up and reproduce the whole procedure from youtube.py in and XCode... I think I checked every step, but still I don't get a valid link. Not sure whether it has something to do with it, but when I run youtube-dl on my computer on a specifc video, I consistently get the same signature length. but when I'm testing my iOS code in the simulator or on actual devices I get different signatures for every call. Decrypting them never gives me a valid link.. Really not sure how to proceed, did someone make progress on this already and can help me???

Are you getting the fmt stream map from the /watch?v=xxx page or the get_video_info? we extract it from the /watch page beacuse the first time we saw the signatures we couldn't use the second page.
If you let us see your code we can try to provide more help.
