<p class="MsoNormal"><span style="font-size:10pt;font-family:"Arial",sans-serif" lang="EN-US">my solution is not simple, I have an outputselectror followed by a fakesink and the muxer. I set the active output to fakesink and switch
it to the muxer when needed. On top of that you need a pad-probe to wait for a keyframe before switching. I’m sure someone else can suggest an easier way.<u></u><u></u></span></p>

<p class="MsoNormal">I am trying to save video and audio when an event occurs, but with 10 seconds before the event. So, I put a queue with max-size-time = 10 seconds and leaking = 2 before the audio

<p class="MsoNormal">Problems arise when I add a blocking probe to the queue src pad, the pipeline freezes after one of the probe blocks. Perhaps this occurred because the muxer is waiting for the buffer
