Building multimedia without gstreamer

[elahav]

Passing -no-gstreamer to configure seems to have no effect (or, at least, not the desired effect). The build still detects gstreamer on my system and decides to use it.

I'm not a CMake expert, but I don't see where that option is handled. qmultimedia/src/multimedia/configure.cmake does not appear to consider it.

Hi,

Which version of Qt are you building ?

[elahav]

@SGaist 6.6

[SGaist]

And you want to build the module with only the ffmpeg backend ?

[elahav]

@SGaist No, ffmpeg and mm-renderer.

To be clear, there is no major problem here. I changed configure.cmake to disable gstreamer if mm-renderer is found, and everything works. It's just the configuration option that seems to have no effect.

@elahav can you share the command you are using to configure Qt ?

[elahav]

../6.6/configure -platform qnx-x86-64-qcc -prefix /system/opt/qt6 -extprefix /data/home/elahav/src/qt/nto-x86_64/host/x86_64 -no-glib -no-gstreamer
