Struct MediaSource

Source

pub struct MediaSource { /* private fields */ }

Expand description

MediaSource is the entry point into the W3C Media Source API. It offers functionality similar to GstAppSrc for client-side web or JavaScript applications decoupling the source of media from its processing and playback.

To interact with a Media Source, connect it to a MseSrc that is in some GstPipeline using attach(). Then create at least one SourceBuffer using add_source_buffer(). Finally, feed some media data to the Source Buffer(s) using SourceBuffer::append_buffer() and play the pipeline.

§Properties

§`active-source-buffers`

A SourceBufferList of every SourceBuffer in this Media Source that is considered active

Specification

Readable

§`duration`

The Duration of the Media Source as a GstClockTime

Specification

Readable | Writeable

§`position`

The position of the player consuming from the Media Source

Readable | Writeable

§`ready-state`

The Ready State of the Media Source

Specification

Readable

§`source-buffers`

A SourceBufferList of every SourceBuffer in this Media Source

Specification

Readable

Object

§`name`

Readable | Writeable | Construct

§`parent`

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit GObject::notify and [deep-notify][struct@crate::gst::Object#deep-notify] signals due to locking issues. In some cases one can use GstBin::element-added or GstBin::element-removed signals on the parent to achieve a similar effect.

Readable | Writeable

§Signals

§`on-source-close`

§`on-source-ended`

Emitted when self_ has ended, normally through MediaSource::end_of_stream().

Specification

§`on-source-open`

Emitted when self_ has been opened.

Specification

Object

§`deep-notify`

The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.
