filter</title></head><body>
<blockquote type="cite" cite><font size="-1">So the idea here is to be
able to resize the frames of a video while it is being streamed so I
can avoid creating a duplicate (resized) of the orginal video on
disk.</font><br>
<br>
<font size="-1">For example, if I have a video that is 1024x768,
but I may want to downsize it to 640x480 when I stream it.
Is this feasible?</font></blockquote>

<div>OK, this is a bit different from what I'd originally thought you
were asking for. What you're actually looking for is *two*
filters: One filter that decodes each incoming frame (into a 'raw'
video frame), and another that re-encodes the frame (into the new
desired size).</div>
<div><br></div>

<blockquote type="cite" cite><font size="-1">I don't have enough
experience with streaming to know if this isn't a good idea for some
reason. But given the pipelined architecture of Live555, I
thought it would make sense to do it this way.</font></blockquote>
<div><br></div>
<div>Yes, you could do it this way - the only caveat being that we
don't provide any codec (encoding or decoding) software ourselves, so
you would need to find another library for doing the decoding and
re-encoding.</div>
