ark::image::VideoBufferPlane

Defined in header “ark/image/video_device.hh”.

---

A plane from the video device. In most cases, there is one plane, but some formats/configurations request multiple planes. This contains the raw bytes/sizes from the device.

Variables

• void * frame= nullptr
  The raw bytes from the remote device.

• size_t allocated_bytes= 0
  The number of bytes allocated for the frame.

• size_t frame_size= 0
  The number of bytes of data within the frame.

• int dma_descriptor= -1
  A file descriptor for this plane (exported from DMA). Only set if request_descriptor was set to true.
