[Fixed]YouTube black screen problem

[sahib12]

Hey whats up, i tried using youtube yesterday and the videos would not show their video, the audio plays fine but the screen is just black, i've tried it with various videos that have worked before, i also tried it on my other xbox and the same problem happened.

Here's the debug log... http://www.xbmclogs.com/show.php?id=71302

I have sort of resolved this, on the plugin settings i changed it from SD only to 'ask' so now it asks me what quality i want it to be. Before on SD only it came up with a black screen, and on 360p i found out it dont work so now i always use 380p but it would of been better if i can just leave the option on SD only so i dont have to choose the quality all the time.

I'd say these are the interesting lines in the log, seems it wasn't able to find an available codec?! It probably went blank cause it was just trying to play the audio stream, which was able to identify (last line below confirms)

You could try looking at the log for same when it works from an "ask", see what's different.
That might help whoever is maintaining the YouTube plugin (see default.py for developer info).

It's possible that might YouTube might use a different video codec per resolution, that would explain why some work and others don't, or maybe the video doesn't actually support the particular size requested by the plugin and it will stream invalid data. From your log I would say this is the video: http://www.youtube.com/watch?v=8VWH13hJQWY

probably was choosing a webm encoded video. settings -> video -> playback and set to "full codec support" for playback of webm currently. youtube should be left on ask anyway for the best choice of resolutions etc.

@Dan, Yes that is the video i attempted to play. I will get that other log up as soon as possible. The strange thing is that it always used to work before on 'SD only' but only recently it has stopped working.

@Buzz, i'll try that, cheers.

It's all good now, i enabled the full codec support and now it works perfectly with SD only. I will leave it on 'ask' though to get the highest resolution. Thanks for the help. Maybe the full codec support option should be enabled manually for future builds?

It uses a lot more ram. Webm might be built into the smaller libs in the future though.
