I have checked existing HAL camera on Link that I posted. But on file:
V4L2camera.cpp only support 3 sensor camera: mt9v113, mt9t111, tvp514x.
1 - On hi253 driver, it register with v4l2 interface with funtion:
- v4l2_int_device_register(&hi253_int_device);
2 - On mt9v113 driver, it register with v4l2 inter with 2 functions:
- /*
* Register as a subdev
*/
v4l2_i2c_subdev_init(&mt9v113->subdev, client, &mt9v113_ops);
mt9v113->subdev.flags |= V4L2_SUBDEV_FL_HAS_DEVNODE;
/*
* Register as media entity
*/
mt9v113->pad.flags = MEDIA_PAD_FLAG_OUTPUT;
ret = media_entity_init(&mt9v113->subdev.entity, 1, &mt9v113->pad, 0); f
I don't understand about this different. I am stucking here. Can you show
me a solution?
