I used to consult whether LGPLed code is compatible with ASL, and people in Apache community show me this link: http://www.apache.org/legal/resolved.html. I found the following words: GNU LGPLThe LGPL is ineligible primarily due to the restrictions it places on larger works, violating the third license criterion. Therefore, LGPL-licensed works *must not* be included in Apache products. After seeing that, i believed that we need to replace FFmpeg. So far as i know, we only use libavcode and libavformat from FFmpeg. As to libpostproc and/or libswscale, i would ask Jiang Shan to confirm whether we use these libs. I will send you the result soon. It would be quite awkward if thing goes like this.......... regards, Kevin 2009/7/24 Bill Stoddard > Bluesky team... > Can you share your latest status with making Bluesky compliant with the > Apache License?
