Thank you, Hector!! This helped greatly, and I got the AIR app working just as expected. This is awesome! Now, I'm just working on getting the AIR app and the ffmpeg files all put inside an installer (.exe and .dmg). Didn't think this would end so easily.
The only downside is that I wont be able to get this working on mobile since the NativeProcess isn't supported. Any ideas on how such a feat can be accomplished through an Android/iOS AIR app?

There are more capturers that use other methods like DirectShow. -framerate 30: the framerate at which the window content is captured. -i desktop: tells the device to capture the desktop, you can also use title="window name" to capture a particular window, you can also capture a particular area, make it output the video in a smaller size (if you are seeing the remote window in a small area why send the original image), etc. -vcodec libx264 -vb 500000 -g 60 -vprofile baseline -level 3.1 -pix_fmt yuv420p -acodec none: tells ffmpeg to stream using h264 in a format Flash understands: -vb 300000 is the bitrate (300kb/s in this case, you could use variable bitrate with different conditions), -g 60 is the keyframe interval, -acodec none tells the stream has no audio, gdigrab doesn't capture the audio anyway. -f flv rtmp://127.0.0.1:1935/live/screenshare: tells to stream the video in Flash video format, to a RTMP server (some local Red5 installation).
