amr codec

하여간에.. 특허가 문제인가..
3gpp 라는 확장자로 youtube mobile에서 서비스를 하고 있기에
pc에서 사용가능한 3gpp codec이 존재하지 않는듯 하고,
그런이유로 인해, 실질적으로 pc에서는 youtube mobile 페이지를 이용할수가 없다.

검색을 해보니 quicktime pro 버전에서는 가능하다고 하는데,
window media player/VLC는 지원하지 않는다.

Please note, that I am not an author of the AMR codec code. The code you can download from this page contains only a shared library wrapper and nothing else. These tarballs don't provide any 3GPP source code. It is downloaded from 3GPP during compilation. To use package compiled by this code, you may need a license from 3GPP. AMR codecs incorporate several patents, held by Ericsson, Universite de Sherbrooke (VoiceAge) and Nokia. VoiceAge claims to provide patent portfolio for AMR codecs. Depending on law in your country, manufacturers and developers may need to get a license. Because it is a shared library, you may need special contract for each one application, which links against this library, directly or indirectly. [링크 : http://www.penguin.cz/~utx/amr]
