Webrtc stream jerky when using wirecast to publish

[wisher1801]

Hi,  When using wirecast to publish video, the video will jerk every few secs and quite blur/pixelated. However when using obs to publish the same video, the video will not jerk and is quite sharp. Both encoders are using on the same pc and publish to be same server. The following are the two encoders setting. Thanks.

We have experienced the same phenomenon.  If you find a solution, please publish it to the group.  We don't own the software, but our customers who do have reported this condition.

Hi All,

@wisher1801,

Did you enable adaptive options?

Please change below parameters:

Key Frame every: 40

Uncheck Stricked Constraint Bitrate

Please increase your bitrate parameter according to your network.

@jmhirsch we have prepared some guides for these applications. Encoder settings are important for streaming. Also, you may check CPU/Network parameters.

I hope, I could help you.

Hi Selim, 

I have changed the keyframe 40 and unchecked the strict constraint bitrate, but the jerky issue still persist. I have emailed you with the details as requested. Thanks.
