I have been trying the play the video test source using the code "gst-launch videotestsrc ! TIDmaiVideoSink" on my leopardboard DM365. I have notice that with the LI-5M03 camera connected, I am able to play the video but without the LI-5M03 camera connected I am unable to play the video. The video test source stop as shown below. Is it possible to run the video test source without the LI-5M03 camera connected.
/ # fbset -disable
/ # gst-launch videotestsrc ! TIDmaiVideoSink

davinci_v4l2 davinci_v4l2.1: Before finishing with S_FMT:
layer.pix_fmt.bytesperline = 1440,
layer.pix_fmt.width = 720,
layer.pix_fmt.height = 480,
davinci_v4l2 davinci_v4l2.1: pixfmt->width = 720,
There is a know issue due the DM365 shutting down the video subsystem if it doesn't detect a working video capture interface. There is an option in the kernel to disable powering off unused clocks.
Just to correct myself: is not an issue with the DM365 per-se, but with the current kernel.
Ok thanks for the information. How do I do about fixing the problem? Can it be fix in the 'make config'?
Can I fix the problem in kernel/linux/arch/arm/mach-davinciboard-dm355-leopard.c?
Do anyone have anything?
In order to play video test on DM365 without LI-5M03 follow this guide:
