<div dir="ltr">Hi Everyone,
<div><br>
</div>
<div>I have a question about mp4mux. In my test scenario mp4mux
is running with faststart=true
faststart-file=/media/test.mp4_TEMP ! filesink
location=/media/test.mp4 , as you can see same path is used
because target machine doesn't have enough ram to handle
faststart-file in memory.</div>
<div><br>
</div>
<div>So in this case test.mp4_TEMP will be renamed or moved to
filesink location?</div>
</div>

No, the filesink is responsible for writing to the /media/test.mp4
and mp4mux doesn't even know which destination the filesink is
writing to. And the temporary file doesn't contain a full valid mp4
file.<br>
<br>
A mp4 faststart file must have its headers before the streams data
(moov before mdat) and mp4mux can only generate a complete moov when
it has all streams data, so it uses a scratch area (the temporary
file) to store the streams data and when it gets EOS on all streams
(all streams are done) it will generate the headers (moov), push
downstream and then start pushing the data it stored to the
temporary file. <br>
