Enumeration Type Documentation

video_buf_memory

enum video_buf_memory

#include <types.h>

video_buf_memory enum

Memory type of a buffer

Enumerator
VIDEO_MEMORY_INTERNAL	buffer is allocated from the internal video heap
VIDEO_MEMORY_EXTERNAL	buffer is allocated from outside

video_buf_type

enum video_buf_type

#include <types.h>

video_buf_type enum

Supported video buffer types of a video device. The direction (input or output) is defined from the device's point of view. Devices like cameras support only output type, encoders support only input types while m2m devices like ISP, PxP support both input and output types.

Enumerator
VIDEO_BUF_TYPE_INPUT	input buffer type
VIDEO_BUF_TYPE_OUTPUT	output buffer type

video_frmival_type

enum video_frmival_type

#include <types.h>

Supported frame interval type of a video device.

Enumerator
VIDEO_FRMIVAL_TYPE_DISCRETE	discrete frame interval type
VIDEO_FRMIVAL_TYPE_STEPWISE	stepwise frame interval type

video_selection_target

enum video_selection_target

#include <types.h>

Video selection target.

Used to indicate which selection to query or set on a video device

Enumerator
VIDEO_SEL_TGT_CROP	Current crop setting.
VIDEO_SEL_TGT_CROP_BOUND	Crop bound (aka the maximum crop achievable).
VIDEO_SEL_TGT_NATIVE_SIZE	Native size of the input frame.
VIDEO_SEL_TGT_COMPOSE	Current compose setting.
VIDEO_SEL_TGT_COMPOSE_BOUND	Compose bound (aka the maximum compose achievable).

video_signal_result

enum video_signal_result

#include <types.h>

Video signal result.

Identify video event.

Enumerator
VIDEO_BUF_DONE	Buffer is done.
VIDEO_BUF_ABORTED	Buffer is aborted.
VIDEO_BUF_ERROR	Buffer is in error.
