Can i.MX6DL receive 1080p60 image through CSI ?

[hyungjunyoon]

Hello?

I  have tested camera through CSI0 in I.MX6DL for android 4.2.2.-1.1.0

I have it68013 hdmi decoder chip that  supports 1920x1080p60.

I can preview 1920x1080p30, 1280x720p60 HDMI input.

but in case of 1920x1080p60, it didn't work. The image is broken a lot.

According to reference manual, IPU CSI supports it. but IC block output supports upto 1920x1080p30.

Are there anyone who knows how to preview 1920x1080p60 camera input ?

Thanks.

Hi hyungjun

except IPU IC nobody can resize image,

so seems there is no way to do that.

Hi Chip,

The Vivante GPU can also support many image formats (including YUV), so that could be an option, though 1080P60 is a lot of pixels, and you may need a custom gstreamer sink to do this.

The VPU is also only rated for 1080P30, so encode will be problematic.

Hyungjun, have you tried previewing at 1080P60 so that re-sizing isn't needed?

Thanks your reply.

I need not to resize image and encode.

So i just want to preview 1080p60 video input in android.

But Androi camera hal is so complicated that i cannot change it.

Please let me know the method.

Thanks

Hello Hyungjun,

Are you using our image? If so, you'll find a boot script in /6x_bootscript.txt. In order to run at 1080P60, you'll need to edit this file to replace the string "1280x720M@60" with "1920x1080M@60" and re-compile it as /6x_bootscript.

You can use our online boot script compiler here to simplify the use of the "mkimage" tool:

Hi hyungjun

for GPU resize you can look below

GPU resize Ubuntu 12.04 - OpenCV Q&A Forum

though I doubt if GPU resize has better performance than IPU IC.
