Question / Help Switching scene freeze the media source

[Ludovic]

Hi !

I will use OBS for multi source via a RTMP server (as described in resources page)
The sources are window capture from a dozen of computer, all streams are 'captured' by my server.

When in my studio, I add a scene for each source add i would like to switch them. But surprise !! the source turns off when i switch.

example:
scene 1 : source 1
scene 2 : source 2

I preview the scene 1 with the source 1 with 1-2 seconds delay (quite good)
I select the scene 2: BLACK!
I return to scene 1: image is freeze !!

From where the problem could come from ?

I use OBS Studio 0.14.2 (windows)

Regards

Please, add 'Video Capture Device' to the Scene Collection and post log from that switching attempt.

Suslik,

I use only 'Media Source' but ok, i add my webcam as source and switch to it, then switch again to my RTMP source.
Here is the log part:

For rtmp try to specify flv at Input Format field. Any changes (new log)?

 

[Ludovic]

I added FLV input format:
here is the log

No change. I first view my live stream (I needed to restart it, hmmm), switch my my cam, switch back to the live stream, BLACK...

Anymay, I decided to use vMix (testing it and succesfuly manage all my live streams)

You may try to uncheck Restart playback when source becomes active at 'Media Source' properties (this can solve some errors from your log).

 

[music422]

Having the same issue here. When I uncheck Restart playback when source becomes active that seems to solve the issue but I have to click OK and then go back in and recheck it. It's very cumbersome for use in a live broadcast.
