Details
In March of this year, i had written a software including a
minimalistic audio-recorder for building an audio-database
for linguistical purposes. Now the recording does not work
anymore and i have tracked down the error to be related with
QtMultimedia and the upgrade of gstramer:
QtMultimedia.QAudioRecorder throws the following warning, when i try to do some recordings: Could not create a media muxer element: "" As you can see here: https://code.woboq.org/qt5/qtmultimedia/src/plugins/gstreamer/mediacapture/qgstreamercapturesession.cpp.html at line 130, this warning is related to gstreamer. And the problem also seems to occur since the gstreamer-update: [2017-05-12 15:24] [ALPM] upgraded gstreamer (1.10.4-1 -> 1.12.0-1) (pacman.log); at least QAudioRecorder surely worked on March and very likely on April, too. As you can see here: https://bugs.launchpad.net/brewtarget/+bug/1407480 there is a problem related to newer gstreamer-versions than 1.10 with QtMultimedia. Of course i already tried to install gstreamer0.10-good-plugins from AUR with all dependencies, but this did not solve the problem for me. |
This task depends upon

That link you posted is almost 3 years old and surely unrelated to
your current issue. Please report this upstream to Qt.
Status with 5.9.2? Have you reported it upstream?
The problem is still present. I needed the software working quite
urgently in that time, so i had to use windows / mac, but i think
i would like to report the bug upstream to Qt in the next weeks.
