Коментарии
Note that although "ogg:" is the wrapper name, the stream is restricted to Ogg files containing a single stream encoded using the Vorbis audio codec. An Ogg container can, in fact, contain multiple streams: audio, video, anything. (Also, the audio streams in an Ogg contaner can use codecs such as FLAC and OggPCM.) The wrapper name is therefore misleading.
