It will then pass-through both audio and video, 113starting from that specific timecode or running time, making sure that 114audio starts as early as possible after the video (or at the same time as 115the video). In the "video-first" mode, it only drops audio buffers until 116video has started.</p> 117<p>The "recording" property acts essentially like a valve connected before 118everything else. If recording is FALSE, all buffers are dropped regardless 119of settings. If recording is TRUE, the other settings (mode, 120target-timecode, target-running-time, etc) are taken into account. Audio 121will always start and end together with the video, as long as the stream 122itself doesn't start too late or end too early.</p> 123<div class="refsect3"> 124<a
