Test patch for endless LiveTV Forcing Jump To 1

comment:1 by tralph11@…, 16 years ago

Using the attached patch LiveTV (using pvr-x50) ran overnight and never failed with over 250+ successful program transitions. The previous test without the patch failed after just 3 transitions.

I've been suffering with this problem for some time. I'll test the patch and see if it helps in my case. Thanks.

(In [20688]) Closes #6605. Fix 'LiveTV forcing JumpTo 1' endless loop.

If playback is in SwitchToProgram() doing a livetv continuous file transition and the decoder reaches the of the file after waitingForChange has been set to true, the decoder will never call the FileChanged() callback to complete the SwitchToProgram() transition.

However, if there is another file in the tvchain NVP will try to force a jump to the next file by calling JumpToNext(true, 1). But, since GetDecoder()-> GetWaitForChange() returns true. JumpToProgram() will never be called to do the transition.

Fix by not testing waitingForChange if a JumpToProgram() is needed.

Thanks to elmojo, and iamlindoro and others for testing.
