[sldev] [PATCH]Improving Recording Movie

[Dave Parks]

You might have more success shooting for an open source equivalent of 
fraps.  I may be naive, but it seems greater performance can be achieved 
if the recording app is a separate process.  The embedded recorder 
really is just for recording bugs, and any serious machinimatographer 
(is that a word?) will already be using an external app for recording.  
If you make your project a standalone app that can attach to the window 
of any other app, you'll have a much larger potential user base.  Maybe 
porting your patch to VLC as an added record feature would work.  That 
project is open source and already deals with the minefield that is 
video format licensing quite well.  A quick peek shows VLC has an 
existing UI for video capture for using video capture devices.  Hooking 
into that should work.  Then you'd be able to stream live video, too.

If a good, free, cross-platform solution to making quality movies 
existed outside the viewer, we could point machinimatographers (there it 
is again!) to that app and remove the recording code from the viewer 
altogether, making one less feature for us to support.
