Provided Methods§

source

fn pause(&self)

Pauses playback of the stream.

If the stream is not playing, do nothing.

source

fn play(&self) -> bool

source

fn realize(&self, surface: Surface)

Called by users to attach the media stream to a gdk::Surface they manage.

The stream can then access the resources of @surface for its rendering purposes. In particular, media streams might want to create a gdk::GLContext or sync to the gdk::FrameClock.

Whoever calls this function is responsible for calling MediaStreamExt::unrealize() before either the stream or @surface get destroyed.

Multiple calls to this function may happen from different users of the video, even with the same @surface. Each of these calls must be followed by its own call to MediaStreamExt::unrealize().

It is not required to call this function to make a media stream work.
