For cameras, however, the Videocapture class is not usually constructed with the file name of the video, but rather the device index that needs to pass the cameraUnlike before, however, the Get () method of the Videocapture class cannot return the exact value of the camera frame rate (fps),

Speak very detailed, to a lot of details are very good, very easy to understand. So ... Notes born　　1, fps-frame per second frame　　The page is that each frame change is drawn by the system (GPU or CPU). But this kind of drawing is different from the dra

the video card supports 2D or 3D??????? Glxgears is a popular OpenGL test that renders very simple gears with output frame rate. Although Glxgears can test the graphics driver's direct rendering capability, it is obsolete and does not represent the current status of the Gnu/linux graphics display and the full capabilities of OpenGL. Glxgears only tested a small subset of OpenGL features. The performance improvements embodied in the glxgears are not felt in the game. It's not really perfect for

Prerequisite Description:　　When doing the GStreamer project, it is necessary to actively send the data collected from the device to the server.This allows you to proactively send data to the specified server using the Tcpclientsink and Udpsink plugins.Tcpclientsink usageNote: If you want to proactively send data to the server, you can transfer it via the Tcpclientsink plugin.The specific code is as followsData-client:Send to Linux:0 - - - 5 4000000 640,480 -O-| gst-launch-1.0 fdsrc! h264pars

(frame second, fps), the larger the FPS value the more fluent the film, but the file will be slightly larger, this I choose 25, Let the fluency not lose too much, and the movie file will be smaller. Step five: In the Files tab, we can select the storage path of the output file (the default is the root of the C disk), select a sufficient disk to hold the file, and then press OK. In computer animated movies,

The problem was of course latency.What John did next when he released QuakeWorld would change the industry forever. client-side Prediction In the original Quake you felt the latency between your computer and the server.

proprietary, but at the moment I focus on Firefox OS and how we can improve on it. Most HTML5 games today are either poorly performing (fps only 0 to 20) or barely pass (FPS reaches 20 to 30). In addition, in most cases, these games can not run at a stable frame rate, resulting in a very unpleasant gaming experience. Interestingly, many problems are actually unrelated to device and JavaScript. Some large

In addition to pressing the F1, there are also F12 function keys are common in two modes, after entering the game, as long as the non-title screen in the scene press F12, will be directly back to the title screen. In addition, Alt+enter is the key to switch between full screen and window, which can be found in the help of RMXP. Next we describe some of the features that appear only in d

The so-called measurement unit is the number of display Frames per Second (Frames per Second, FPS) In general, 30fps is acceptable, but improving the performance to 60fps can significantly improve the interaction and authenticity. However, generally, a higher smoothness is not obvious if th
