<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am hoping to get some advice from you on
the following task.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Basically we are trying to implement a
pipeline reading (by a customer GStreamer element) raw frame
data from disk, pass to ffmux_mov, which generates mp4, and
passes to a fdsink.
</p>
<p class="MsoNormal">If the fdsink is associated with a disk
file, we get a mp4 file and everything is fine.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">However, we were asked to associate the
stdout to the fdsink so that the mp4 is not created under the
disk, but directly get outputted to the stdout as an http
response to the Client. This doesn’t work. The main issue is
that the ffmux_mov tries to send SEEK events to the fdsink to
set write-pointers to different positions of the mp4 to handle
headers, trailers etc. As the stdout is not a seekable
resource, this wouldn’t work.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I wonder has anyone tried this before. </p>
<p class="MsoNormal">Have I missed something?</p>
<p class="MsoNormal">Can ffmux_move be modified to work in the
above scenario?</p>
<p class="MsoNormal">Is there other good ways to do the above,
such as using other containers instead of mp4?</p>
<p class="MsoNormal">Any advice is highly appreciated.</p>
