mxc_v4l2_still.out high resolution issue

[weikeng-jimmy]

Hi Sir,

I will use mxc_v4l2_still.out function to capture YUV422 format image, and follow FSL-UT-V4L2-002.txt from mxc_v4l2_test/doc .

The image view is normal when capture resolution of "640x480" . But I change resolution from 640x480 to 1280x720 (or 1920x1080), the image view is NG.

Below is Test Procedure :

mxc_v4l2_still.out -w 640 -h 480 -f YUV422P

The image can be viewed with:

mxc_v4l2_output.out -iw 640 -ih 480 -ow 640 -oh 480 -l 100 -f 422P still.yuv

The image should be the correct image, clear and with the correct colors.

Original Attachment has been moved to: FSL-UT-V4L2-002.txt.zip

Hi WKJIMMY

some sensors require additional coefficients loaded through i2c for supporting

additional resolutions, what sensor used in the case, had you tried with gstreamer.

Please refer to attached Linux Guide sect.7.3 Multimedia use cases. Supported resolutions

can be checked with  $ gst-inspect mfw_v4lsrc

Best regards

Hi Igor,

The test environment is Sabre-SD boad and camera sensor is OV5642 (OV5640 MIPI have some situation).

My customer need capture YUV domain but linux user's guide not have.
