The problem is that at somepoint filesrc is checking the filesize
and it is not aware that it changes.<br>
<br>
You could try using a pipe instead of files (fssink+fdsrc instead of
filesink,filesrc). Otherwise we might need a flag on filesrc to
restat the file for each read and if size changed send a duration
change.<br>

What format are you using. Could you explain the scenario
better. Do you wnat
to relay a we-stream? Maybe you can stream the video
without writing it to a
file buffer.<br>
