| Requires: >= Qt 5.1 for the x11extras module (or else you need to |
| get x11extras from gitorious yourself) |
| |
| This example illustrates how to integrate Gstreamer GL plugin with |
| Qt. In particular it uses glupload with fakesink elements to create |
| texture with decoded video frame. This texture is shared with |
| QGLWidget derived class, which paints a cube with video texture on |
| each face. |
| |
| To compile the example, include and library paths might be adjusted in |
| .pro file according to your installation of the gstreamer and |
| corresponding development files. Most probably, the adjustments will |
| be necessary on Windows. |
| |
| To run the example simply start executable file after compilation. If |
| there is no command line arguments provided, then videotestsrc element |
| will be used to generate video. The following pipeline will be created |
| in this case: |
| |
| videotestsrc ! video/x-raw, width=640, height=480, framerate=(fraction)30/1 ! glupload ! fakesink sync=1 |
| |
| It is also possible to provide the video file name as a first command |
| line parameter, i.e. ./qglwtextureshare myvideo.ogv . In this case, |
| the following pipeline will be executed: |
| |
| filesrc location=myvideo.ogv ! decodebin2 ! glupload ! fakesink sync=1 |
| |
| I would appreciate any feedback and improvement suggestions for this |
| example. |
| |
| Have fun :-) |
