Qt multimeia GStreamer-Critical error!
-
Is that on your Pi or on your desktop ? If on your Pi then there's something strange since it talks about a i386 version of the package and the Pi is an ARM based machine.

Are you trying to install x86 (32bit) version?

Please show the command you use to install the GStreamer packages.

@SGaist
the command line is :
1,sudo apt-get install gstreamer1.0
2,sudo apt-get install libgstreamer-plugins-good1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev libgstreamer1.0-0 libqgsttools-p1 libqt5multimedia5-plugins gstreamer1.0-libav libges-1.0-dev libgstreamer-plugins-bad1.0-dev libgstreamermm-1.0-0v5 libgstreamermm-1.0-dev libqt5gstreamer-1.0-0 libqt5gstreamer-dev libqt5gstreamerquick-1.0-0 libqt5gstreamerui-1.0-0 libqt5gstreamerutils-1.0-0 libqtglib-2.0-0 libqtgstreamer-1.0-0 libqtgstreamer-dev libqtgstreamerui-1.0-0 libqtgstreamerutils-1.0-0 qtgstreamer-plugins-qt5 qtgstreamer-plugins ubuntu-restricted-extras
some packages may be useless,i don't know exactly.
when trying to rebuild QtMultimedia module with gstreamer1.0 ,following the steps:
1, run command1 && command 2,
2, cd qt5.7.1
run ./configure -gstreamer 1.0
(NO need to rebuild qtbase and other modules.)
3, cd to qtmultimedia folder
run qmake
run make install
is it right? thank you ! -
Which qmake did you use ?
-
@SGaist
the qmake is the path of qt5.7.1 installed ,it was generated by the last make install (with default gsteamer 0.1), is it right way as you mentioned ¨just re-build the QtMultimedia module. ¨? -
Which version exactly ? You seem to have started by configuring a new version of Qt rather than build the QtMultimedia module with the version your already installed.

@SGaist
the version is QT5.7.1 i have install with QtMultimedia using gstreamer0.1.
i try to rebuild the QtMultimedia module with the version i already installed,
should i parse what parameters to let the QtMultimedia module know that it should use gstreamer1.0 instead of gstreamer0.1? can you give instructions please? -

@SGaist @jsulm
thank you for your great support,
but i found a strange thing:
i can not play the .wmv or .mp4 video even when i try to use QT5.8(install by qt-opensource-linux-x64-5.8.0.run, host is ubuntu 16.04),
after i install Qt5.8, i use the Qtcreator4.2.1 to open the project player under multimediawidgets Example, run the example, and open a Wildlife.wmv(example video under windows 7), try to play it ,just no video .output is :
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0I installed gstreamer with following commands:
1,sudo apt-get install gstreamer1.0
2,sudo apt-get install libgstreamer-plugins-good1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev libgstreamer1.0-0 libqgsttools-p1 libqt5multimedia5-plugins gstreamer1.0-libav libges-1.0-dev libgstreamer-plugins-bad1.0-dev libgstreamermm-1.0-0v5 libgstreamermm-1.0-dev libqt5gstreamer-1.0-0 libqt5gstreamer-dev libqt5gstreamerquick-1.0-0 libqt5gstreamerui-1.0-0 libqt5gstreamerutils-1.0-0 libqtglib-2.0-0 libqtgstreamer-1.0-0 libqtgstreamer-dev libqtgstreamerui-1.0-0 libqtgstreamerutils-1.0-0 qtgstreamer-plugins-qt5 qtgstreamer-plugins ubuntu-restricted-extras
can you check it for me? the video is OK, i can play it with gst-play-1.0 or with double click.
ps: i try to play a *.mp3, it works well, and there are sounds playing with no pictures if the format is mp4
