Field Documentation

◆ internal

AVV4L2RequestFramesContextInternal* AVV4L2RequestFramesContext::internal

Internal context for the initialized V4L2 stateless decoder/encoder session.

Definition at line 41 of file hwcontext_v4l2request.h.

◆ pixelformat

uint32_t AVV4L2RequestFramesContext::pixelformat

V4L2_PIX_FMT_* coded pixel format to set on the OUTPUT queue (decoders) or the CAPTURE queue (encoders) during initialization.

This field must be set by caller before av_hwframe_ctx_init() is called.

Definition at line 49 of file hwcontext_v4l2request.h.

◆ bit_depth

uint32_t AVV4L2RequestFramesContext::bit_depth

Optional bit depth of the frame pixel format, e.g.

8 or 10.

This field should be set by caller before av_hwframe_ctx_init() is called, the field will be updated to match the selected frame pixel format after successful initialization.

Definition at line 58 of file hwcontext_v4l2request.h.

◆ init_controls

struct v4l2_ext_control* AVV4L2RequestFramesContext::init_controls

Optional codec-specific extended controls to be set during initialization.

These fields should be set by caller before av_hwframe_ctx_init() is called, fields are reset to NULL and 0 after successful initialization.

Definition at line 66 of file hwcontext_v4l2request.h.

◆ nb_init_controls

int AVV4L2RequestFramesContext::nb_init_controls

Definition at line 67 of file hwcontext_v4l2request.h.
