Class Details¶

class GstMse.SourceBuffer(**kwargs)¶

Bases:: Gst.Object
Abstract:: No
Structure:: GstMse.SourceBufferClass

The Source Buffer is the primary means of data flow between an application and the Media Source API. It represents a single timeline of media, containing some combination of audio, video, and text tracks. An application is responsible for feeding raw data into the Source Buffer using GstMse.SourceBuffer.append_buffer() and the Source Buffer will asynchronously process the data into tracks of time-coded multimedia samples.

The application as well as the associated playback component can then select to play media from any subset of tracks across all Source Buffers of a Media Source.

A few control points are also provided to customize the behavior.

GstMse.SourceBuffer :append-mode controls how timestamps of processed samples are interpreted. They are either inserted in the timeline directly where the decoded media states they should, or inserted directly after the previously encountered sample.
GstMse.SourceBuffer :append-window-start / GstMse.SourceBuffer :append-window-end control the planned time window where media from appended data can be added to the current timeline. Any samples outside that range may be ignored.
GstMse.SourceBuffer :timestamp-offset is added to the start time of any sample processed.

New in version 1.24.

abort()¶

Raises:: GLib.Error
Returns:: TRUE on success, FALSE otherwise
Return type:: bool

Attempts to end any processing of the currently pending data and reset the media parser.
