Capturing Decklink to jpg with ffmpeg

ffmpeg -f dshow -s 720×576 -i video=”Decklink Video Capture” f:captest_%d.jpg

Note this was using a PAL SDI source and output very quickly.

Here is also pushing out the stream as RTMP to a Wowza server:

ffmpeg -f dshow -s 720×576 -i video=”Decklink Video Capture” -vcodec libx264 -f flv -coder 0 -aspect 16:9 rtmp://xxx.xxx.xxx.xxx/live/enctest -s 512×288
