[gst-devel] mov unfinished

[sudarshan bisht]

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.

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.
