* [PATCH] pxa_camera: Fix YUV format handling. @ 2008-11-06 23:04 Robert Jarzmik 2008-11-06 23:52 ` Guennadi Liakhovetski 0 siblings, 1 reply; 8+ messages in thread From: Robert Jarzmik @ 2008-11-06 23:04 UTC (permalink / raw) To: video4linux-list, g.liakhovetski Allows all YUV formats on pxa interface. Even if PXA capture interface expects data in UYVY format, we allow all formats considering the pxa bus is not making any translation. For the special YUV planar format, we translate the pixel format asked to the sensor to VYUY, which is the bus byte order necessary (out of the sensor) for the pxa to make the correct translation.

In your patch for mt9m111 you do + case V4L2_PIX_FMT_UYVY: + mt9m111->swap_yuv_y_chromas = 0; + mt9m111->swap_yuv_cb_cr = 0; i.e., you call mt9m111's default format "UYVY", and again, I think, this is logical. If both datasheets are correct, this is also the format expected by the PXA, so, you should translate YUV planar to UYVY. Have you tested it?

Yes, the patch is wrong. It's UYVY (Cb Y Cr Y). I'll amend the patch. > i.e., you call mt9m111's default format "UYVY", and again, I think, this > is logical. If both datasheets are correct, this is also the format > expected by the PXA, so, you should translate YUV planar to UYVY. Have you > tested it? Yes, I had. And I didn't saw the problem. I checked again today, and the image is greyish. I was using my phone and myself as the picture model. My pullover is white, I'm grey lately, the background is grey also, as is the phone. Thus, even if the image looked correct, it was not. I tried again today the planar YUV422P, but with a bright red pullover. With either UYVY or VYUY, the colors are not displayed, all remains grey. I don't really know if the problem comes from my image transformation (yuvsplittoppm), or from the pxa_camera driver. I'll dig deeper this week-end. > Do I understand it right from the pxa270 datasheet, that UYVY would be the > only possible format if it were used for overlay2?

Eventually we would also like to have a Tested-by from him. Yes, of course. -- Robert PS: I didn't mentioned it yet, but I had amended the mt9m111 patch, because format_by_fourcc() in soc_camera.c is looking for YUV422P in mt9m111 formats, even if pxa_camera translates the format.
