enable color_key in runtime

alexv — Mon, 17 Jun 2019 08:30:01 GMT

Hello, I have an application that is responsible for viewing video with gstreamer.
The main application is shown in /dev/fb0 and the video in fb1.
I have configured fb0 to be the foreground and I also configure the color key to show the video that is in the background.
The problem is that I enable the color key only when I'm going to play video and I disable it when there is no video.
When I play the video I have the following Warning:

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08000000
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00100000
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00800000

What would be the right way to do this and avoid warnings?

This warning does not appear if I always leave enabled the color_key.

So I think the problem is to enable/disable the color_key in runtime.

Thanks!

Hi Alex

one can try with latest linux L4.14.98_2.0.0 link
linux-imx - i.MX Linux kernel
NXP Linux documentation
i.MX Software | NXP

In general issue may be caused by incorrect ipu initialization, recommended to

fully disable it then initialize with new configuration.

Best regards
igor
