imx6 QMediaPlayer low framerate

  • Hello, i've got IMX6 board and build Qt 5.12.3 for it. I'm using Qt example which plays video on widget with QMediaPlayer. On my x86 desktop everything is ok, but on IMX6 board video framerate is very low and i see a lot of messages "A lot of buffers are being dropped". When i'm trying to play video on imx6 board with gst-play, it is ok. Also, i compared outputs of codec library in both cases(gst-play and QMediaPlayer -they are same ). So why Qt on imx6 is so slow?
