Streaming YouTube videos?

[cybershaman]

Is it possible to watch YouTube videos "live"? I mean so that they are played while they are still downloading. I'm not using MVP so it's unnecessary to transcode the flv into mpg.

No. I could have added this, but it would have needed to have youtube video window with its normal controls shown at the bottom (ie, their activex control), and wouldnt have integrated nicely with GB-PVR (normal keys wouldnt have worked etc), which didnt sounds very nice to me.

There are no directshow components that I know of for streaming FLV files from a URL. If anyone knows of any, then let me know know and I'll be happy to look into coming up with a better scheme.

Gabest has made a FLV splitter for DirectShow. I can play flv files just fine with it. Ffdshow handles the video decoding. Also the flv files can be played on the fly so the video can be still downloading when it's played.

Here's link to the FLV splitter

I did look into using that filter, but wasnt able to get it to work with a either a URL or file that was still downloading. Are sure it is possible? If so, what graph do I need to make in GraphEdit to see it in action?

I'll do some testing and get back to you on that...

Didn't have time to write any test programs but it seems that there is indeed some issue playing unfinished files. I used FireFox to download the file and while it was downloading, I was able to play that file (the .part file) with MPC. But I couldn't get it to work in GraphEdit.

Here's how the graph looked when MPC played that file:

There would probably have to be a custom source filter to handle this task.

Yeah, but thats exactly what I was trying to avoid. Youtube just isnt that important to me, so I'd rather not spend the time doing that.

I tried this myself, and it kind of worked, but didnt play for long before locking up. It looks like the splitter doesnt cope with the file continuing to grow.

Did it play to the the end of the video for you?

[cybershaman]

Yes, you are right. It doesn't play at the end.

I'll do some more research on this...maybe there is a solution.
