[coherence-dev] Youtube error <type 'exceptions.AttributeError'>: 'NoneType' object has no attribute 'url'

[Dominik]

Hi again,

my frontend is a XBox 360 and my config is much simpler:
    [[YouTubeStore]]
        name = Coherence - YouTube   
        quality = hd
        proxy_mode = buffered

But back to your problem:
-I think the jerky playback is because of your proxy_mode setting
cache_maxsize and buffer_size only take effect if proxy_mode is set to buffered or cached

-I think the exception you (sometimes?) get is caused by a bug that only occurs if you are using an userid
I have no youtube account yet so I can debug it at the moment sorry 
maybe someone else can jump in here

FYI I have just started to dig onto coherence and its backends
so don't take my word for granted :-)


Hi!

Thanks, I appreciate any tips. My device is Buffalo Linkstation live.

What's your frontend? I'm using PS3 and the Youtube videos seem to
have have jerky playback despite of the quality and buffer settings.
On the PS3 browser the same videos play flawlessly.
