Failed in adding output to video-engine

[Phillipip]

In Europe, a frame rate of 25 is common. However, if I try to change the room's frame rate to 25 and add it to the list of allowed frames, I get the error message when subscribing to the stream: Failed in adding output to video-engine. Are there any ideas about this?

If you are using software compositor,

diff --git a/source/agent/video/videoMixer/SoftVideoCompositor.cpp b/source/agent/video/videoMixer/SoftVideoCompositor.cpp

If you're using MsdkVideoCompositor, make similar changes as above.

Thank you for the hint. Wouldn't it be better if the frame and keyframe rate as passed by the room could be used correctly?

Because there was no such requirement before, and various settings will increase testing overhead.
