Comment (by WilliamDeRieux@…):
Replying to [comment:3 pbennett]:
> Can you supply a short video file that has this problem. Also please let
us know what your setting is for video playback profile.
I wouldn't be able to supply any video due to copyright/broadcast
liscensing (even a short one)
I use OpenGL for both painting and rendering....the playback profile that
I use now is 'OpenGL Slim' but I was using 'OpenGL High Quality'.
It only seemed to happen when using OpenGL -- the other painters/renders
were fine.
I also fixed the issue in my copy of the source.[[BR]]
MythPlayer::ChangeSpeed() will call VideoOutput::FallbackDeint() before
then calling VideoOutputOpenGL::SetupDeinterlace[[BR]]
The problem seems to be in the deinterlaing methods because it will call
QOpenGLContext::makeCurrent() on the wrong thread.[[BR]]
[[BR]]
-- I simply commented out the body of the FallbackDeint() method since I
don't use deinterlaing and as a result I haven't had this issue occur
after.
this what that method looks like now:
{{{
/** \fn VideoOutput::FallbackDeint(void)
* \brief Fallback to non-frame-rate-doubling deinterlacing method.
*/
void VideoOutput::FallbackDeint(void)
{
/*SetupDeinterlace(false);
if (db_vdisp_profile)
SetupDeinterlace(true,
db_vdisp_profile->GetFallbackDeinterlacer());*/
}
}}}
