<p>Hello,<span style="font-size:12.0pt"><o:p></o:p></span></p>
<p>You could try untrunc: <a href="https://github.com/ponchio/untrunc">https://github.com/ponchio/untrunc</a><o:p></o:p></p>
<p>But you need a reference file from the same source, and your mileage may vary with how much it will gather out of it.<o:p></o:p></p>
<p>In gstreamer land to get around this, you need to send the end of stream event. I think sometimes the muxer might play nice with you and write the moov atom while going to null state, but it isn't something you should count on. If you are using the command
line, I believe you need the -e flag so it sends and waits for EOS when you hit CTRL+C.<o:p></o:p></p>
<p>Hope that helps!<o:p></o:p></p>
<p>Cheers,<br>
Michael.<o:p></o:p></p>
