If ffmpeg includes any of the GPL codecs, then ASF code cannot have dependencies on ffmpeg. Whether LGPL is acceptable or not depends on how the LGPL code is linked into the ASF code and build time. ASF projects can do dynamic (runtime) linking to LGPL code. ASF projects cannot statically link to LGPL code. Bill
