Mutable methods for crate::cudacodec::CUDA_EncoderCallback

Required Methods§

Source

fn as_raw_mut_CUDA_EncoderCallback(&mut self) -> *mut c_void

Provided Methods§

Source

fn on_encoded( &mut self, v_packet: &Vector<Vector<u8>>, pts: &Vector<u64>, ) -> Result<()>

Callback function to signal that the encoded bitstream for one or more frames is ready.

§Parameters
  • vPacket: The raw bitstream for one or more frames.
  • pts: Presentation timestamps for each frame in vPacket using the FPS time base. e.g. fps = 25, pts = 3, presentation time = 3/25 seconds.
Source

fn set_frame_interval_p(&mut self, frame_interval_p: i32) -> Result<bool>

Set the GOP pattern used by the encoder.

§Parameters
  • frameIntervalP: Specify the GOP pattern as follows : \p frameIntervalP = 0: I, 1 : IPP, 2 : IBP, 3 : IBBP.
Source

fn on_encoding_finished(&mut self) -> Result<()>

Callback function to that the encoding has finished.
