Hi!
(Sorry for my previous post, I sent it while typing it..)
So the issue is the following:
Creating a video4linux producer like (simplified code):
producer = new Mlt::Producer(*profile, "video4linux2:/dev/video0");
consumer->connect(*producer);
consumer->start();
It works fine. But when I want to stop the capture, there is no way to stop the
video4linux producer. Deleting the producer and the consumer still leaves the
video4linux device open.
After a few hours of struggling, I figured out that some stuff was kept in the
cache. Adding :
mlt_service_cache_purge( MLT_PRODUCER_SERVICE(parent) );
to producer_close (as already done for the qimage producer for example) fixes
the issue.
It seems correct to me but maybe there was a reason not to do so...
Patch below, regards
