 Replying to [comment:10 cehoyos]:
 > Sorry, patch 1 needs {{{./configure && make ffmpeg.exe}}} to test...

 I have updated the output from patch 1 and it too seems to work.  I have
 also run {{{ make ffmpeg.exe }}} on the patch2 branch and it completes
 without error.

 However, when built in this manner, and trying to run the command at issue

 {{{./ffmpeg.exe -f dshow -i video="Logitech HD Webcam C310"}}}

 You get

 {{{
 $ ./ffmpeg.exe -f dshow -i video="Logitech HD Webcam C310"

 }}}

 which I'd imagine is caused by it not being cross-compiled and thus it
 isn't possible to diagnose the filed issue using this build.
