Description
GstBin that auto-magically constructs a decoding pipeline using available decoders and demuxers via auto-plugging. The output is raw audio, video or subtitle streams.
decodebin3 differs from the previous decodebin (decodebin2) in important ways:
- supports publication and selection of stream information via GstStreamCollection messages and GST_EVENT_SELECT_STREAM events.
- dynamically switches stream connections internally, and reuses decoder elements when stream selections change, so that in the normal case it maintains 1 decoder of each type (video/audio/subtitle) and only creates new elements when streams change and an existing decoder is not capable of handling the new format.
- supports multiple input pads for the parallel decoding of auxilliary streams not muxed with the primary stream.
- does not handle network stream buffering. decodebin3 expects that network stream buffering is handled upstream, before data is passed to it.
decodebin3 is still experimental API and a technology preview. Its behaviour and exposed API is subject to change.
