Youtube blocking mp4's?

Yeah, it's not something about which I know a great deal but as an experiment, I recently made a short inworld video, converted it to mp4, stuck it on http://www.fileden.com/ and pointed my parcel media url at it with the player here /54/ff/246637/1.html and it still seems to be working ok. So in principle it seems possible.

Please excuse my noobness. and I hope this isnt too off topic. I have a youtube question semi-related...I have 4 videos that I wish to play in a loop Is there an updated way to read the video length into a timer so if I change a video it will still loop correctly playing all 4 videos completly before changing the media URL? I would like to do it with no manual timer settings.

sure, you'd just have to script your timer to accommodate. as for getting the video length, if you get the source of the youtube page, the video runtime can be found if you search the source for "length_seconds": (including quotes)

ahh nice so parse the source for that string and set the timer var to that...thanks i'll do some searchin on how thats done
