Ask you a question, and I learned the Internet: "the most common application is in the workspace window layerlayer", my question is, there are two CLIENT APP, one is the QT APP, a gstreamer video decoding execution is rendering, excuse me everybody, they are run by default in the workspace layer? If so, is there a way to make QT APP always run on gstreamer, without being blocked by gsteamer picture? Thank you very much!
