<div>I guess it may be the way qtmux writes the header info . If it writes the header info at the end of the file then there should be a proper way to close the file i.e. by sending EOS event . Because if closing of file is done without sending EOS event then qtmux may not write the header info to the file.</div> <div> </div> <div>And ffmux_mov is writing the header info at the beginning of the file so that does not require the notification of the EOS event.</div> <div> </div> <div> </div> <div><br><br> </div> <div class="gmail_quote">On Sat, Jun 26, 2010 at 1:02 AM, Stefan Kost <span dir="ltr"><<a href="mailto:ensonic@hora-obscura.de">ensonic@hora-obscura.de</a>></span> wrote:<br> <blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote"> <div class="im">Am 24.06.2010 16:16, schrieb Overkill:<br></div> <div> <div></div> <div class="h5">> I'm developing an embedded camera that records<br>> video in .MOV format.
