GstSourceBuffer

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 gst_source_buffer_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.

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.
append-window-start / 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.
timestamp-offset is added to the start time of any sample processed.

Properties

append-mode

“append-mode” GstSourceBufferAppendMode *

Affects how timestamps of processed media segments are interpreted. In GST_SOURCE_BUFFER_APPEND_MODE_SEGMENTS, the start timestamp of a processed media segment is used directly along with timestamp-offset . In GST_SOURCE_BUFFER_APPEND_MODE_SEQUENCE, the timestamp of a processed media segment is ignored and replaced with the end time of the most recently appended segment.

Flags : Read / Write

append-mode

Affects how timestamps of processed media segments are interpreted. In GstMse.SourceBufferAppendMode.SEGMENTS, the start timestamp of a processed media segment is used directly along with timestamp-offset . In GstMse.SourceBufferAppendMode.SEQUENCE, the timestamp of a processed media segment is ignored and replaced with the end time of the most recently appended segment.
