QML MediaPlayer, Raspberry Pi 4. gst_alsa_device_new: assertion 'caps' failed error
-
I've tested a video streaming from host, I can receive video successfully on RPi, but only in terminal.
If I launch a Qt app with Media Player it receives but it's broken screen is blinking with only black image, in console I have this strings:
gst_alsa_device_new: assertion 'caps' failed
In Media Player I enter only address to video
MediaPlayer { id: player source: "udp://192.168.0.152:10001" video Output: video }
I've discovered that it's only a problem with Qt. Do I need to reinstall it from the ground up or check for Gstreamer libs, but I've already checked it?
Qt version - 6.3.2, builded for RPi from sources via cross-compiling
It's all working normally on x86
