Stream does not work anymore (c59d34ac804f)

Oct 24, 2014 at 11:18 AM

i have problems with my live stream. The Stream does not work anymore. Tested with SamplePlayer.WP81

Here the Link for testing

After buffering the playing stops and an exception was thrown at mediaStreamFacade.RequestStop(); in the Close Method of the StreamingMediaPlugin class

Here some Debug-Output (with some german words):

Could you try with what I just checked in (bcbb069207bc)? Some of the changes were related to cancellation exceptions with StreamingMediaPlugin. It seems to be playing with the SamplePlayer.WP81 that I have here.

Note that if you are changing streams, then you need to "player.Source = null;" before setting .Source to the url you want. See here for more on that workaround.

With bcbb069207bc stream works fine.

Good to hear that it works for you.. Thanks for letting me know.

I did see the failed ObjectPool assert in your log. It should be safe for you to ignore it (unless you have some other reason to think you are having problems with memory leaks).
