Hi All,
Today I tested video playback by gst-play, the sound is perfect without any lag, but the display looks abnormal. when sliding pictures, the display looks good and the same board is no problem to play video by burning android image. both of yocto and android share the same DDR initial code, so I think it doesn't matter of DDR crosstalk. the yocto branch I used is imx-linux-zeus/imx-5.4.3-2.0.0.xml, the print message and photos are attached as below:
root@imx6dlsabresd:~# ./gst-play 1080p_t1.mp4
Volume: 100%
Now playing /home/root/1080p_t1.mp4
State changed: buffering
