Screenshare framerate very low

the framerate is changed to 5 when I start screen share.
but when I change to p2p, the framerate seems change to 25.

I have config
desktopSharingFrameRate: {
min: 25,
max: 25
},

I check the chrome://webrtc-internals ,find “googFrameRateOutput” and “googFrameRateReceived” is always 5 or 6 when “googFrameRateSend” is 25

In your config.js, try:

testing: {
p2pTestMode: false,
capScreenshareBitrate: 1
},

I have try capScreenshareBitrate=1
but it has no effect

Did you check the ending comma in the p2pTestMode line?

yes, it has no problem
