Hello, Thanks for report this Low FPS issue. I found it is true for IA device(around 10 FPS) while on ARM device, Crosswalk can get FPS near 30. I have created a but to track it: https://crosswalk-project.org/jira/browse/XWALK-2643 We will begin to investigate it soon. You can track the progress in the link.

I can't say the exact number but it looks like a 30 fps. Under crosswalk it looks like 5 fps. those numbers are indicative because i cannot get values.

It seems Chrome has this “not able to change FrameRate” bug in https://code.google.com/p/chromium/issues/detail?id=381698 and I think the fix is on the way. About the low FPS, What is the FPS you got on your side? If the FPS is lower than Chrome, that will be a Crosswalk bug and We will fix it.

I have been trying with both crosswalk-7.36.154.13 and crosswalk-8.37.189.8. I also use easyrtc under crosswalk and everything works fine. Also under easyrtc (that uses getUserMedia) is not possible to change framerate. ----Messaggio originale---- Da: [email protected]<mailto:[email protected]> Data: 23/09/2014 7.46 A: "[email protected]<mailto:[email protected]>"<[email protected]<mailto:[email protected]>>, "[email protected]<mailto:[email protected]>"<[email protected]<mailto:[email protected]>> Ogg: RE: [Crosswalk-help] Some strange behaviour about rtc Hello, Thanks for the question. First, can I know the Crosswork version you are using?

I am trying to use rtc capabilities to shoot photo using getUserMedia. I see that video capture framerate is very low. Following w3c specifications about media constraints i tryed to change framerate but i always get an error. This is the code. var constraints = { audio: false, video: { mandatory: { minFrameRate: 30 }, optional: [{ sourceId: this.videoSources[this.currentCameraIndex] }] } }; navigator.getUserMedia(constraints, this.successCallback, this.errorCallback); Is it possible to change such framerate in crosswalk? I am trying this code on a intel based android tabled. Thanks
