Hi all,
has anyone an idea to manage the quality of a youtube video?
Today we ware able to manage the youtube uploader or the youtube category.
More and more customers are asking if it is possible to manage the quality of a youtube video. There are tools available to manage this localy on the endpoint. But this would be great directly on MWG.
Cheers,
Thorsten

youtube continually adds new codecs, allowed resolutions and relaxes size restrictions: http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs . A video file which has been uploaded two years ago can have an another set of available resolutions and quality settings than a video which was uploaded recently using best practices http://support.google.com/youtube/bin/answer.py?hl=en&answer=1722171 (which means youtube skips reencoding).
This means you cannot set a quality parameter in the youtube url without parsing a web page to find a list of available qualities.
A small javascript injected in the youtube web site by a custom MWG7 rule can do a trick and override a youtube' logic to always choose a high available resolution / quality setting.
On the other side youtube try to restrict a possible url manipulation by introducing a url signing and expiration timestamp:

there are some programms and scripts in Internet which can bypass these restrictions and d/l a video directly ...
Hey coooool,
will try it.

just remove range parameter from the link, just like
