no need for a single page for vfwcap, since a lot of people don't even know what it is and the page title is generic, so this method should be included in this page also

    9 You can also possibly use the (now out dated) [[vfwcap]] device. 
     9Or you can also possibly use the (now out dated) '''[http://ffmpeg.org/ffmpeg.html#vfwcap vfwcap]''' input device, like this: 
     10 
     11To list the supported capture devices, connected to the machine: 
     12{{{ 
     13ffmpeg -y -f vfwcap -i list 
     14}}} 
     15 
     16That will give us the list like this: 
     17{{{ 
     18... 
     19libavutil     50.36. 0 / 50.36. 0 
     20libavcore      0.16. 1 /  0.16. 1 
     21libavcodec    52.108. 0 / 52.108. 0 
     22libavformat   52.93. 0 / 52.93. 0 
     23libavdevice   52. 2. 3 / 52. 2. 3 
     24libavfilter    1.74. 0 /  1.74. 0 
     25libswscale     0.12. 0 /  0.12. 0

     29list: Input/output error 
     30}}} 
     31 
     32So, we can try to grab something from our camera: 
     33{{{ 
     34ffmpeg -y -f vfwcap -r 25 -i 0 out.mp4 
     35}}} 
     36 
     37Where "'''-i 0'''" is the index (zero based) in the list of present capture devices ("'''Driver 0'''").
