[FFmpeg-user] Any Mac OS X users interested in ffmpeg AppleScript droplets? - here's one for cat

Concatenate similar video files using this AppleScript.

How do I use it?

Copy the lines containing +ACI-begin script+ACI- through +ACI-end script+ACI- to your Mac's clipboard. Paste the clipboard contents into a Script (or AppleScript, depending on your version of OS X) Edtor window, then save as an application. Name your video files successively, and drop them all onto the AppleScript application's icon.

What does it do?

Uses your compiled version of the ffmpeg executable to concatenate the files in ascending order, creating the resulting file in the same location as the files you dropped. The ffmpeg executable should be compiled using Homebrew+ADw-http://brew.sh/+AD4- and/or be accessible by your command line shell at /usr/local/bin/ffmpeg. You should be able to change that specification in the AppleScript if you keep ffmpeg somewhere else.

I+IBk-ve tested with .m4v files containing 5.1 audio. Please help me test others. Thanks.
