Hi,

I am using IMX-6Q sabre AI board and trying play a MP4 video by using gstreamer. When i am through my gstreamer command pipeline starts running but video is not playing on the monitor through HDMI cable.

Here I want to know, is any settings are required for HDMI display.

Thanks in advance

I suggest you to read the documentation (section kernel boot parameters): i.MX_6DualQuad_SABRE_AI_release_notes.pdf

The i.MX6 is not publicly available so you have access to a dedicated web site where you have probably downloaded the Linux BSP.Otherwise, you should ask to the Freescale field application engineer responsible for your project.

Have you set the bootargs for an HDMI display in UBoot? The syntax is different from the i.MX53. Here are some examples I have tested on the Nitrogen6X board:

printenv

set bootargs 'console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24'
set bootargs 'console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24'
set bootargs 'console=ttymxc1,115200 video=mxcfb0:dev=hdmi,1920x1200M@60,if=RGB24'

save

Sir Montgomery

Could you tell me a little about how to change the UBoot settings? Do i need to install first?

I am blank about Uboot, but my image on IMX6 gave no signal to HDMI monitor

Thank you
