About display position settings for gplay

Dear All,


We are developing a display application using gplay for our product using i.MX8M.


gplay can set the display position using the "z" command.

We did some positioning, but one did not work as intended.


The command used is as follows:

   $ gplay-1.0 --video-sink=kmssink big_buck_bunny_4k_h264_30frame.mp4




Even if you use 4K size video, the display position setting on the positive side was possible.

   Input [x y width height]: 1920 1080 3840 2160




However, the display position setting on the minus side seems to be ignored.

   Input [x y width height]: -1920 -1080 3840 2160




Does anyone have any advice on how to negative coordinate settings?


*We used L4.14.98_2.0.0_ga demo SD image and i.MX8M-EVK (Rev. B4) for this check.

*The video source used was obtained from the following URL:
