I am also using the CSI1 port of i.MX53 with the TI Video Decoder TVP5147M1 for interfacing the PAL output Camera.

When we run the camera test command, we are just getting the first frame on the display, instead of getting the stream.

Also, we are getting the below errors in the debug window.

Any idea what could be the issue???

Thanks!

Hello Lin Yang,

We have still not resolved this issue. For time being, we are using as USB based capture device (EasyCAP) for video streaming. We are suffering with high CPU usage to stream & capture the video with this capture device.

Regards,

Gopi

Are you using the port CSI1 or CSI0?

I am trying to capture the video from TVP5147M1 (on evaluation kit), but when it is captured, I am having two frames coming as a single frame.

Were you able to get the TVP5147M1 work for streaming the video?
