|
* This element will drop all buffers until a specific timecode or running
|
|
* time has been reached. It will then pass-through both audio and video,
|
|
* starting from that specific timecode or running time, making sure that
|
|
* audio starts as early as possible after the video (or at the same time as
|
|
* the video). In the "audio-after-video" mode, it only drops audio buffers
|
|
* until video has started.
