For release groups : With the help of Gabest, we could establish a system where every release group gets its own PW, and Gabest hardcodes them all into DVobSub. That way all SSA streams could be stored encrypted in the MKV or OGM file, and DVobSub has the PW for them, so people can view them, but not extract them , unless they are skilled programmers. If only Gabest was here, i guess this could be implemented in no time ....
简单的说就是可以给matroska里面的字幕加密了........
放的时候需要密码才能打开.........
而gabes可以在vobsub里面给每个fansub内置密码.......
普通人播放的时候就可以自动解码......
但是要想把字幕提取出来就不行了........
