Hello,
I use yocto morti with x11 distro, and try to display gstreamer on screen.
qt5 application shows without any issue.
But gstreamer pipelines are distorted with green lines. I use rtp pipeline. simpler pipeline with videotstsrc, looks better.
I suspect that x11 is competeing on same display. On stopping the gstreamer application, the desktop manager pops in. even if I try to display x11 with :
systemctl set-default multi-user.target
I still get xterm terminal pop in.
We also noticed high memory bus usage, even before starting pipeline (read is about 450MB/s in mddc profiler)
So, it makes us suspect that they compete on the display.
1. Is it that x11 yocto distro should not be used with gstreamer, and we better change to fb distro ?
2. Can I disable x11 completely ?
3. Is it possible to command gstreamer pipeline to display on the other hdmi output (there are 2 hdmi outputs in board) ?
Regards,
Ran
Hi Ran
please try nxp offical bsps and nxp gstreamer plugins described on
for x11 please refer to attached Linux Manual Chapter 17 X Windows Acceleration
for disabling x11 check Yocto Guide sect.5.1 Build configurations.
Gstreamer examples are given in sect.7 Multimedia Linux Guide.
Best regards
igor

Hello Igor
We are still struglling with this issue...
Now we suspect that it is a matter of ethernet paket loss.
I have opened a new question here:
