DisableVideoOutput() freeze

Hi
I have written an application to send 4k output on SDI4K decklink card.
In my application First I intailze device, and enable video output with display mode, preroll with 5 frames
and then start the StartScheduledPlayback allmost same steps as sample file TestPattern.cpp
when I call Stop, in my stop function i have the following statements
StopScheduledPlayback(0, NULL, 0);
DisableAudioOutput();
DisableVideoOutput();

when it comes to DisableVideoOutput(), it just freezes here, doesn't come out at all

In forum i saw so many people facing this issue. Could you please tell how should i solve this issue.

Regards
Basav

Hi Basav,

Could you please show / describe how your application schedules frames for playback and advise the thread context from which DisableVideoOutput[1] is called?

Cheers,
