Re: [Spice-devel] Information about video detection
Hi, I go on the website with another browser (chrome) but i don't think that it can change the result and the qxl driver is installed on the VM. I don't know how to get the size of the stream created, can you explain me? The test that i made is: open the excel file, in full screen, and going up an down quickly (same test on website). I put log on mjpeg_encoder and stream functions, to observe this stream creation. It takes about 10 seconds to launch a stream detection.

Re: [Spice-devel] Information about video detection
hi, 1. in this post, it mentions RED_STREAM_FRAMES_START___CONDITION, i do not find it in source code. 2. what is the threshold of video detect? 3.action of excel opertions are very slow, could you tell me where(source code) i should look into to locate this problem? thanks 在 2013-07-02 22:47:35，Matilde Yanez yanez.mati...@gmail.com 写道： 2013/7/2 Yonit Halperin yhalp...@redhat.com On 07/02/2013 10:22 AM, Matilde Yanez wrote: Hi, thanks for answers. 2013/7/2 Yonit Halperin yhalp...@redhat.com mailto:yhalp...@redhat.com Hi, On 07/01/2013 04:27 AM, Matilde Yanez wrote: Hello, I need some information about video detection, on VM.
