[Ffmpeg-user] FFmpeg licensing issue

Hi I have a query on last question:http://ffmpeg.sourceforge.net/legal.php Q: Since FFmpeg is licensed under the LGPL, is it perfectly all right to incorporate the whole FFmpeg core into my own commercial product? It is clear that we need to pay for a commercial product. What is the % of the amount to pay? And is MPEG-LA the only authority to pay? With Best Regards suryya
