About management of frame buffer in i.MX6DQ.

Question asked by Keita Nagashima on Jun 9, 2014

Dear Sir or Madam,

 

Hello.

I have a question about management of frame buffer in i.MX6DQ.

 

BSP: Yocto L3.10.17_1.0.0

 

I tested the 4 multiple video play (overlay) with different video clips by gstreamer. 

But, I couldn't understand the relation between the video playback and the frame buffer.

(video1 --> fb0?, video2 --> fb1?)

 

[Question]

I'd like to confirm the relation between the video playback and the frame buffer.

Please tell me the way of confirming a used frame buffer.

 

[My Playback command]

gst-launch playbin2 uri=file:///home/mount/trailer1.mp4 video-sink="mfw_isink axis-left=0 axis-top=0 disp-width=640 disp-height=480"

& gst-launch playbin2 uri=file:///home/mount/FSL_Mosaic_Video_1280x720_H264_7mbps.mp4 video-sink="mfw_isink axis-left=400 axis-top=0 disp-width=640 disp-height=480"

& gst-launch playbin2 uri=file:///home/mount/mp4_h264_aac.mp4 video-sink="mfw_isink axis-left=0 axis-top=400 disp-width=640 disp-height=480"

& gst-launch playbin2 uri=file:///home/mount/mp4_mpeg4_aac.mp4 video-sink="mfw_isink axis-left=400 axis-top=400 disp-width=640 disp-height=480"

 

Best Regards,

Keita
