<p class="MsoNormal">Hello all.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">I have rtsp camera which streams h264 to the appsink. Then, sometimes, I need to grab it by appsrc and write it to the file.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I was able to make it with the following pipelines:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">rtspsrc->rtph264depay->appsink<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">appsrc->h264parse->matroskamux->filesink.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Everything works as expected. But, as in h264 stream, I-frames can be transmitted once per 20 - 30 seconds, sometimes I've got 10 seconds of corrupted video before the fist I-frame and good video starts.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Is there are any way, to ignore everything before first I-frame or start file form first i-frame? I've tried with splitmuxsink and tried to google, but with no success.<o:p></o:p></p>
