Hi Lisandro,
Sorry for the long reply: it seemed like some activity has been going
on the Qt bug, but it turned out to be Qt5-only. As the last quote
goes, this would hardly be fixed or reviewed for Qt 4:
"Most likely not. Before Qt 5, QtMultimedia was part of the Qt
Mobility project, which is not maintained anymore."
In this case, what's the policy on inclusion of patches for
essentially dead upstream?
