Expand description
Interface for video demultiplexing. :
User can implement own demultiplexing by implementing this interface.
Required Methods
fn as_raw_RawVideoSource(&self) -> *const c_void
Provided Methods
sourcefn last_packet_contains_key_frame(&self) -> Result<bool>
fn last_packet_contains_key_frame(&self) -> Result<bool>
Returns true if the last packet contained a key frame.
sourcefn format(&self) -> Result<FormatInfo>
fn format(&self) -> Result<FormatInfo>
Returns information about video file format.
sourcefn get_extra_data(&self, extra_data: &mut Mat) -> Result<()>
fn get_extra_data(&self, extra_data: &mut Mat) -> Result<()>
Returns any extra data associated with the video source.
Parameters
- extraData: 1D cv::Mat containing the extra data if it exists.
sourcefn get(&self, property_id: i32, property_val: &mut f64) -> Result<bool>
fn get(&self, property_id: i32, property_val: &mut f64) -> Result<bool>
Retrieves the specified property used by the VideoSource.
Parameters
- propertyId: Property identifier from cv::VideoCaptureProperties (eg. cv::CAP_PROP_POS_MSEC, cv::CAP_PROP_POS_FRAMES, …) or one from @ref videoio_flags_others.
- propertyVal: Value for the specified property.
Returns
true
unless the property is unset set or not supported.
