capture_to_stream() [3/3]

BufferOperation MayaFlux::Kriya::BufferOperation::capture_to_stream ( const std::shared_ptr< IO::IOManager > &  io_manager, const std::string &  filepath, IO::VideoLoadConfig  config, uint64_t  ring_frames = 0, std::optional< Portal::Graphics::RenderConfig >  live = std::nullopt, std::optional< Portal::Graphics::RenderConfig >  display = std::nullopt  )

static

Capture a video file straight into a dynamic video stream it creates.

The video counterpart of the camera form: it loads the file, hooks it to a buffer and appends each played frame to a ring sized from that buffer.

Parameters

ring_frames	Frames the ring keeps; zero keeps three seconds at the registered frame rate.
live	Draws the playing file when given.
display	Draws the stream through the pipeline's IOManager when given; the pipeline needs one.
