On some MKV files the following happens.
Either on of the 2 things, situation 2 and 3:
1: PLay movie OK, exit Movie OK
2: Play movie, black screen, exit not possible
3: Play movie OK, exit black, screen exit not possible.
With the iOS remote apps starting a movie that always plays, exits the weird behavour when in black screen mode
I have an full debug log of situation 2:
It's not the mkv itself. Sometimes, playing the file upto 3-5x times it plays ok.
it may be related to the swicht refreshrate. in combination with the pause to switch which also is not working. It
Any more info can be provided. Perhaps its the type or codec type of the mkv, not sure. The same mkv works some times, some times it does not. it seems not to happen when fps= refreshrate and no switch is required.
it would appear that if the switch takes too long and no canvas is available to render to the screen stays black even if the switch eventually finished. This could also explain why it previously worked, because the pause of 2,5 second still worked.
