-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Package: libqtmultimediakit1 Version: 1.2.0-3+b1 Severity: normal
After many wasted hours trying to understand how to get ppsspp's Qt interface to use ALSA, I ironically find it does a very poor job (whose fault that is I dont know...), but I must report here on my related findings regardless. The way libqtmultimediakit1 is built from qtmobility results in a hard dependency with pulse audio, which is presumably unacceptable as pulse should not be a requirement to use the very important Qt framework (I run a pure ALSA system after fleeing the broken pulse as a n00b long ago). Upstream is flagging this as a packaging issue - https://bugreports.qt-project.org/browse/QTBUG-29742 - which feels dubious, but thats why I'm reporting here. In the qtmobility source, because there is no special platform config (features/platformconfig) for our environment, when the 'configure' script is ran it determines what features to include based on what it can compile at the time (see line 601 onwards). I have the pulse audio headers installed as other packages depend on them (but I don't use pulse, and this is fine as I don't expect the presence of these headers to break unrelated stuff). When pulse is detected, the audio plugin 'libqtmedia_pulse.so' is compiled, BUT ALSA SUPPORT ISNT. See 'multimedia/audio/audio.pri' at the bottom, it literally looks for pulse audio and only if it isn't enabled, enables ALSA! The end result is a user with a pure ALSA system running a program that uses libqtmultimediakit1 and getting a permanent hang when audio is first used, as libqtmedia_pulse.so cannot cope with no running pulse audio server (see previously-mentioned https://bugreports.qt-project.org/browse/QTBUG-29742 - I don't see why its acceptable to do this either...). Please can the pulse audio dependency be clearly marked and libqtmultimediakit1 be built in an ALSA-supported form separately?
