FfmpegWriter

Struct FfmpegWriter 

Source
pub struct FfmpegWriter { /* private fields */ }
Expand description

Saves video frames to a video file using ffmpeg.

This spawns an ffmpeg process and pipes the frames as raw video (-f rawvideo) with no intermediate format conversion on our side; ffmpeg performs whatever conversion the chosen encoder requires. The ffmpeg process is spawned lazily on the first frame, once the frame width, height and pixel format are known.

Implementations§

Source§

impl FfmpegWriter

Source

pub fn new( fname: &str, ffmpeg_codec_args: FfmpegCodecArgs, rate: Option<(usize, usize)>, ) -> Result<Self, Error>

Source

pub fn write_dynamic_frame( &mut self, frame: &DynamicFrame<'_>, ) -> Result<Duration, Error>

Write a frame. Return the presentation timestamp (PTS).

Source

pub fn close(self) -> Result<(), Error>
