TX2 capture embedded line data

Hi everyone,

I use TX2 the bsp version is r28.2,I want to capture embedded line data from camera, how to modify driver? Thanks.

You need to make sure the sensor have output embedded data first.
Then you can using argus API to get it.


Hi ShaneCCC,

We capture sensor image data use V4L2 API, our application not use L4T Multimedia API. Can I get embedded data use V4L2 API?

Have a check the vi4_fops.c there emb_buf_addr to get the embedded data from the sensor. However current this buffer didn’t send back to user space you may need to modify the driver to send it back to use it.

Could you give me a patch? Thanks.

Sorry, I don’t have it.
