Currently I faced with a big problem with the video playback performance. When I try to open mp4 video file from any of QML video examples, I got a high CPU loading (~40%) and the video is freesing and jerks (in not dependence on the window sizes). Though, using a C++ examples I got satisfactory performance (with the ~7% CPU loading).
I have installed the K-Lite Codec Pack, where are automatically are used the LAV decoders to playback (in both cases as for C++ and as for QML).
