To provide a framework to handle different kinds of DRM solutions at the device end?<o:p></o:p> I saw there is a discussion in 2005 but there is no further update.<o:p></o:p> <o:p> </o:p> We want to provide a GStreamer-based solution to play media contents protected by OMA DRM 1.0. OMA DRM 1.0 is a open DRM standard. It wraps or encrypted the original media content in a wrapper file format. I wonder whether GStreamer will provide a standard workflow for us to write decryption plug-ins for the pipeline.<o:p></o:p> <o:p> </o:p> Thanks<o:p></o:p> Amanda<o:p></o:p> </div> </body> </html>
