Dear All,
I want to convert RGB565 format to PNG format.
When I converted the RGB565 to PNG format in i.MX25, the below execution was failed.
Could you tell me What's the problem?
And could you tell me how to convert the image except for using ffmpeg if there is?
For image convertion, I used the captured RGB565 format image via i.MX25 Camera.
I used the below command to capture the RGB565 format image on the EVK.
~ $ modprobe fsl_csi
~ $ modprobe ov2640_camera
~ $ modprobe csi_v4l2_capture
~ $ /unit_tests/mxc_v4l2_still.out -f RGB565
And I executed the below command in the Desktop(Ubuntu10.10) and the Board(i.MX25).
~ $ ffmpeg -vcodec rawvideo -pix_fmt rgb565 -s 640x480 -i still_RGB565.yuv -f image2 -vcodec png still_RGB565.yuv.png
When I used the upper command, I could create the PNG format file but I couldn't create the PNG format file.
When I executed the command, the below error was occurred.
root@freescale /test/png_rgb565$ ffmpeg -vcodec rawvideo -pix_fmt rgb565 -s 640x480 -i still_RGB565.yuv -f image2 -vcodec png still_RGB565.yuv.png
