## Description

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 "video-first" mode, it only drops audio buffers until video has started.

The "recording" property acts essentially like a valve connected before everything else. If recording is FALSE, all buffers are dropped regardless of settings. If recording is TRUE, the other settings (mode, target-timecode, target-running-time, etc) are taken into account. Audio will always start and end together with the video, as long as the stream itself doesn't start too late or end too early.
