<p>Hello,</p>
<p>You could try untrunc: <a class="moz-txt-link-freetext" href="https://github.com/ponchio/untrunc">https://github.com/ponchio/untrunc</a></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.</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.</p>
<p>Hope that helps!</p>
<p>Cheers,<br>
Michael.<br>
