[FFmpeg-user] Question about the LGPL

Hello I'm a French student doing a work experience placement and I have to program a software using videos. But the videos are in .avi and I have to convert it to .flv That's why I found your software. I download it with Windows XP and it works (I haven't already writte a line of code) But the finality of my work experience placement is commercial software. I have some question about the right of using your software. Can I use the ffmpeg.exe if I only use it to convert videos to .flv? (The software will be write in VB.net). Thanks.
