Changes (by Marton Balint):

 * priority:  important => normal

Comment:

 By default ffmpeg opreates in single threaded mode, therefore if cuda
 initialzation takes time it will probably block capturing frames.

 The workaround is most likely specifying e.g. ```-thread_queue_size 100```
 or similar.
