Qt4 is only one of several views to the playlist.

in the Player object.

The position is an input parameter, not a return value.

According to the MPRIS specification, the Position property of the
Player object must be an int64.

dbus microsecond position overflows the unsigned 32-bit integer at
about 35:48 into a track's playback.  A 64-bit integer still means
an overflow, but after more than 292000 years into a track's playback.

ffmpeg modules were renamed too some time ago

avoid confusing old versions of ffmpeg

show the invalid options for the first stream only (following dictionaries are identical)
free all the options array

Obsolete "ffmpeg" prefix
Use "avformat" or "avcodec" prefix
avio has no options (yet)
switcher uses "sout-switcher" prefix
Use "sout-avformat" for muxer

If rate stays at 0, a FPE will be raised in SetupOutput.

The D-Bus specification forbids parts of well-known bus names to begin
with a digit. This patch changes the instance-specific part of the bus
name to .instance<pid> instead of -<pid> in order to comply with the
MPRIS v2.2

see: http://specifications.freedesktop.org/mpris-spec/2.2/#Bus-Name-Policy

This fixes #6599

And do the same with aout_Fifo since only aout_Packet uses it.

'control' and 'extraintf' will be checked for occurences of 'macosx', which, if found, in turn will be removed. Other contents of these settings won't be touched. Same for all the other prefs.

Shared anonymous mapping did not make much sense.
