I use FireFox v.29 in Windows XP; I installed Video DownloadHelper. I want to convert the videos as soon as I download them. In the preferences of the extension there's a box that says "enable conversion". As I check that box I'm asked to install an external application to do that. I press the button that says "install/update converter". This opens a page of the official site of Video Download helper. It says I need to install FFmpeg to convert the videos. I go to ffmpeg.org to download it, the download page tells me I must dowload it from http://ffmpeg.zeranoe.com/builds/. So I donwload the 32-bit static build and I extract its files from the compressed folder. That's as far as I go. There's no installation file inside; there are three executable files inside: ffmpeg,exe, ffplay.exe, and ffprobe.exe. I've opened all three of them and entered the Video DownloadHelper preferences after that. The problem is that when I try once again to check the box for "enable conversion" I'm once again told that I have to install the external application. What am I doing wrong? In the official site of Video DownloadHelper there are a step by step explanation but for another converter: ConvertHelper, so they aren't really helpful. Can you please help me?
