<p class=MsoNormal>Hey all, I have searched quite a bit, but haven't found a
good answer. So I thought I'd post it here.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a custom video device which gives me a simple framebuffer,
(24-bit BGR).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to stream it elsewhere, but would like to
encode/compress it in realtime.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>On the client side, I would decode it, and display it in an
OpenGL window.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have it working today, with uncompressed images, but it is
killing the network (as one would expect).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Are there any examples for making something like this work?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>In short:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>[Custom Video Framebuffer] -> [encode] -> [network]
-> [decode] -> [display]<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Considerations that I have to deal with:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='margin-left:27.0pt;text-indent:-.25in;
mso-list:l1 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>1.)<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Relatively
realtime. I have <16ms to encode a 640x480x3 frame buffer, and ship it
off.<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:27.0pt;text-indent:-.25in;
mso-list:l1 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>2.)<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>I
need a streaming-type on the wire format. The clients may be turned on/off
at any point, so i need to support this.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The naive implementation, is simply running the video frames
though zlib, which is shrinking the data nicely, but it's rather expensive, and
makes me feel dirty. All of the examples I can find, are reading off an
existing encoded file, but not quite what I need.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks for your input<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
