Qt 5.15.2 gstreamer avi playback error
-
Hello!
I want to play video files on raspberry in QtMultimediaWidget, it works fine, but in the case of avi files, the picture is delayed compared to the sound. Same error when running from terminal with gst-launch.
The video is good, it is perfect with vlc on another computer, and it is also interesting that the error does not appear when playing mkv files.Does anyone have any idea what could be the source of the error?
Thanks

Hi,
One thing that comes to mind is that there's no hardware acceleration happening for that file.
What are its specifications ?
Did you try with ffmpeg as well ?Interested in AI ? www.idiap.ch

I did a bit of research and it was recommended to increase the kernel gpu_mem setting, so maybe the hardware acceleration will work, but the interesting thing happened, if I increased the default 64MB to 128, the error remained, but if I decreased it to 16MB , the error does not appear. -
