+=== Example recipe: live screen capture to webm ===
+
+Here's a recipe used by one user for doing a live full-screen 1920x1080 screen capture to WebM format (VP8/vorbis).  Note that you may need to tweak the -cpu-used or -b:v parameters depending on how fast your system is.
+
+{{{
+SET "audio_device=<audio_device>"
+SET "video_device=<video_device>"
+SET "threads=<physical cores minus 1>"
+ffmpeg -f dshow -i audio="%audio_device%":video="%video_device%" -c:v libvpx -b:v 2M -deadline realtime -cpu-used -5 -threads %threads% -c:a libvorbis -y output.webm
+}}}
+
+It seems that the audio and video might not be perfectly in sync, but this should be a good starting point and may be "good enough" for some.
