We would like to multi-display on 3 different interface, HDMI、LCD and LVDS

We use this command to play video on specific framebuffer

"gst-launch filesrc location=/test.avi typefind=true ! aiurdemux ! queue ! vpudec ! mfw_v4lsink device=/dev/video16"


We found that if we put lvds on fb1

Using the above-mentioned command, it can play video correctly on specific framebuffer(fb1).

But if we found that if we play video on fb2(hdmi), the video size on fb2 is not correct


Could you tell me how to solve this problem?
