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.
