Struct AVHWFramesConstraints

#[repr(C)]
pub struct AVHWFramesConstraints {
    pub valid_hw_formats: *mut AVPixelFormat,
    pub valid_sw_formats: *mut AVPixelFormat,
    pub min_width: c_int,
    pub min_height: c_int,
    pub max_width: c_int,
    pub max_height: c_int,
}

This struct describes the constraints on hardware frames attached to a given device with a hardware-specific configuration. This is returned by av_hwdevice_get_hwframe_constraints() and must be freed by av_hwframe_constraints_free() after use.

Fields

valid_hw_formats: *mut AVPixelFormat

A list of possible values for format in the hw_frames_ctx, terminated by AV_PIX_FMT_NONE. This member will always be filled.

valid_sw_formats: *mut AVPixelFormat

A list of possible values for sw_format in the hw_frames_ctx, terminated by AV_PIX_FMT_NONE. Can be NULL if this information is not known.

min_width: c_int

The minimum size of frames in this hw_frames_ctx. (Zero if not known.)

min_height: c_int

max_width: c_int

The maximum size of frames in this hw_frames_ctx. (INT_MAX if not known / no limit.)

max_height: c_int
