Hello all,
I have an issue with the following script:

Basically, it *can* work sometimes (1 on 10 times), but most of time I just
got a freezed picture with only one or two sub-stream displayed. This is the
NVIDIA version but I have exactly the same issue with standard avdec_h264
and v4l2h264enc plugins.
I suspect a sync issue, but not sure. If I try this script with 5
videotestsrc, it works perfectly. Same thing with a direct display of the
compositor result (no encoding / streaming), with nvoverlaysink. It works
also all the time.
I'm lost right now, no idea of what I can do / try to fix it.
If anyone has any idea, it would be great !
Thanks a lot,
Mael
