10 | | Transcoding from a lossy format like MP3,AAC,Vorbis,Opus,WMA etc. to the same or different lossy format might degrade the audio quality even if the bitrate stays the same(or higher). This quality degradation might not be audible to you but it might be audible to others.[[BR]] |

92 | | Please note Opus streams are currently not muxable in MKV containers. Only Ogg Containers are supported at the moment. MKV container support is should be available in the future[[BR]] |
93 | | When compatibility with hardware players doesn't matter then use libvorbis in a MKV container rather than libfaac when libfdk_aac isn't available[[BR]] |
94 | | When compatibility with hardware players does matter then use libmp3lame or ac3 in a MP4/MKV container rather than libfaac when libfdk_aac isn't available[[BR]] |
