ok. Thank you. I did it. Sorry one more time. Half a year past I remember all pjsua command line orders - not so bad, as now. I used command *vid call cap X Y* and I successfully changed between web cams. as I see - resolution of video streaming (video call) leaves the same as was before change the device. and, as usual, QUESTION appears: Can I change the resolution of video call , i.e. 352x288 -> 640x480. One web camera can provide more quality video than another, and I want to show the best quality I can achieve. -------------- next part -------------- An HTML attachment was scrubbed...
