Does Qt Phonon support setting playback speed
I use the Qt Phonon in developing a multimedia player。
I need to set the playback speed, but I did not find the relevant API in Phonon::MediaObject or others class。
Does Qt Phonon support setting playback speed ？
I am also interested in changing the playback speed, but as far as I know it is not possible in Phonon.
The phonon backends should support this easily, so I don't know why this is not part of the Phonon API
Anyone know more about this issue?
