Curl a JPG from a MJPG stream
Lets say I want to curl a JPG file from this MJPG stream, how can this be done?

I tried using curl but it just keeps capturing the entire stream.

curl -o ~/Desktop/sample.jpg http://204.248.124.202/mjpg/video.mjpg

curl retrieves webpages, it doesn't decode videos. You'll have to use something like transcode perhaps to extract individual frames.

do you know of any other way I can do this or how to get started with transcoding?

mjpegtools can probably do what you want. Installing now to test.

It only supports its own crazy formats, not normal mjpeg. Had better results with mplayer so far:

Code:
mplayer -vo jpeg video.mjpg

But I don't know how to autostop it after x frames.

This works perfectly, saving 00000001.jpg in the current directory:

Code:
mplayer -frames 1 -vo jpeg http://204.248.124.202/mjpg/video.mjpg

Thanks, trying to find mplayer for osx binary now. Will try and report back.

I can't find command line mplayer for OSX. Could this be done any other way?

Did you check Fink or Macports? They both have mplayer packages/ports.
