Hello,
I work with a patch where I read 3 video streams from v4l devices, created with the vloopback kernel module.
hmm, since v4l(1) has vanished from the kernel, i'm afraid i cannot do much testing right now.
I tried down grading to 0.92.3, which was the stable when I designed this patch, but the result is the same.
are you sure that you are using 0.92.3, after downgrade?
if indeed both 0.93 and 0.92 are affected by your issue, then the problem is likely to be outside of Gem...
If I test the v4l stream with for example VLC the stream runs smooth.
even when reading all 3 streams in parallel?
The video streams are generated with LiVES 1.4.4. It supports the vlooback output options. It is a UYV clamped stream, 280 pix wide:
does lives have an output option for v4l2loopback?
What could be the cause that just one stream at the time plays in GEM?
if the problem is indeed Gem (which might well be), then i would suspect some locking problems in the threading. try sending an [async 0/1( message.
