FFMPEG read camera stream on OSX about imageio

[kuchi]

I got this to work with the pull request that I have, but I have to use my own FFMPEG binary. The one you have hosted does not seem to support video cameras on OS X. The binary you have gives the error:

Unrecognized option 'list_devices'.

What version is your ffmpeg binary?

Ah, not I see you wrote in the other issue "you do need to have ffmpeg installed through home-brew or some other means where it is correctly compiled for supporting cameras. Static builds for OS X on the web don't seem to support cameras."

Is this certain, or is it worth trying to update the lib. Otherwise we should put this information in the ffmpeg plugin documentation.

The current version of the static ffmpeg binary you are hosting does not have support for avfoundation which is required on OS X to use cameras. I confirmed current static builds at https://ffmpeg.org/download.html#build-mac do work with the cameras but the -list-devices option to ffmpeg is missing/depreciated. However I updated the code yesterday to deal with that. So, if you just update to the above static build all should be good. The cameras work now on OS X. I can access my built in camera using without an issue.

Here is the specific static build I tested that works with the cameras: http://evermeet.cx/ffmpeg/ffmpeg-2.6.3.7z

Which one did you check? http://ffmpegmac.net/ or http://evermeet.cx/ffmpeg/?

Doh, you actually mentioned that already :)
