Good to know. > ffmpeg can decode (but not encode because of patents) MPEG-2 in main. Where was this decision made? Is there a mailing list post or other link you can point me to? It seems strange that encoding support is not included when decoding is included since the MPEG LA charges the same for each [5]. Of course, there could be other patent holders that charge more to license their encoding patents. Also, it is possible that the use of encoding software for MPEG-2 is more actively litigated. Do you know which of these is the case? It would be nice to know how Debian makes decisions on things like this. When it comes to patented codecs, what constitutes "safe enough"? How does one determine if the patents for a codec are being "actively litigated"?
