With sufficiently new Qt5 and GStreamer versions, this should be
relatively easy. Qt5 has dedicated i.MX6 support. Try installing
gstreamer-imx to use the VPU for video decoding. This places the video
frames into DMA buffers, which the GPU can render directly from. This
way, the rescaling is done by the GPU. As a bonus, the YUV->RGB
conversion is then also done by the GPU.

Hi all
I'm working on imx6dlsabresd clone board.
I have to play a FHD video (1920x1080) into a small QVideoWidget
(530x300), driven by QMediaPlayer object.
The bsp is based on Krogoth.
Is it possible to rescale the video using hardware acceleration?
Thanks
MZ
