Download Helper on Mac error - Conversion requires external application??

Hey guys,

I'm looking for some help with the Download Manager extension on Mac for the Firefox internet browser... When I attempt to use Download Manager, I get a pop up error that states:

Conversion requires an external application that appears to be missing on your system.
Configure conversion? > Cancel > OK

When I select OK, it opens the Preferences for Download Manager, highlighting in red the location path for the selected converter option, which is either:

FFMpeg
or
MEncoder

The path in the field next to the drop down selector for the above 2 options is highlighted in red... I'm assuming that means it's invalid?

I'm not sure why this happened or what changed, because when I originally installed the Download Helper, it worked fine... I attempted to use it today and now it won't work.

I'd appreciate any help you can offer! Thanks!

iMac 20", Mac OS X (10.5.6)

Hey, I had the same problem and just solved it. Your path to the console video converter is incorrect or you don't have any of the two convectors program is looking for.

Solutions: if you have one of these converters just type in the path. Tip: you can find you their path by typing it in spotlight or try write: "which aaa" in console line, where aaa is "meencoder" or "ffmpeg", that should return the path where they are located. If it doesn't then might that they are installed on your machine.

Installing ffmpeg: download source file from this link: http://www.ffmpeg.org/releases/ffmpeg-0.5.tar.bz2 then open command line and write : cd and the absolute path to the file for example "cd /use/john/Desktop/ffmpeg". Then type in : "./configure && make && sudo make install" in the command line to compile the ffmpeg, after process finishes you have just to specify path "/usr/local/bin/ffmpeg" in DownloadHelper.

Hope that helps!

Download the file that was posted, open the folder and double click on the configure icon, once it does its thing go back to the folder screen scroll down and open the folder called ffpresets, this should do something in the terminal program that was opened after clicking the Configure icon. Wait til its done. Then double click the folder called libavcodec, if it doesn't do anything in Terminal then thats ok. Now I tried downloading a video from youtube just so I could get the downloader helper preferences up to the screen where it asks for the path of the converter (ffmpeg). I opened up Spotlight (top right-hand corner of mac) and typed in what was mentioned above "which ffmpeg" the top file it highlighted said "utils.c-libavformat" put your mouse over it and it should show a little screen that tells you the Path. For example mine was something like this: /Users/ME/Desktop/ffmpeg-0.5/libavformat once thats typed in the red lettering should turn to black. If it does your good to go, try downloading and converting a video.

Hi, I just tried to get this to work with no avail. I tried the steps listed above but when it goes to convert videos is just sits there in progress indefinitely. One thing funny in the instructions is that when I opened either of the two folders, 'ffpresets' or 'libavcodec,' nothing happened in the terminal (why would clicking into a folder execute anything anyway??). Also, why would you link to the libavformat folder and not one of the other ones (even though utils.c-libavformat did pop up first for me as well)? Did this process work for anyone else?
