    2929Here are some popular formats with encoders listed that ffmpeg can use:[[BR]]
    3030{{{
     31Dolby Digital: ac3
     32Dolby Digital Plus: eac3
     33MP2: libtwolame, mp2
     34Windows Media Audio 1: wmav1
     35Windows Media Audio 2: wmav2
    3136LC-AAC: libfdk_aac, libfaac, aac, libvo_aacenc
    3237HE-AAC: libfdk_aac, libaacplus
     
    3742Based on quality produced from high to low:[[BR]]
    3843{{{
    39 libopus >= libfdk_aac >= libvorbis >= libmp3lame > libfaac > Native FFmpeg AAC >= libvo_aacenc > Native FFmpeg Vorbis
     44libopus >= libfdk_aac >= libvorbis >= libmp3lame > eac3 >= ac3 > libfaac > libtwolame > aac > wmav2 >= wmav1 > mp2 > vorbis > libvo_aacenc
    4045}}}
    4146Even though AAC should generally give better quality than MP3 at the same bitrates libmp3lame should give better quality output than libfaac.[[BR]]
     47This list is just a general idea and there might be cases where codecs listed to the right might perform better than those listed to the left at certain bitrates. [[BR]]

    43 Please note it is not recommended to use (libfaac/Native FFmpeg AAC/libvo_aacenc) for AAC encoding.[[BR]]
    44 Please note it is not recommended to use Native FFmpeg Vorbis for Vorbis encoding.[[BR]]
     49Please note it is not recommended to use 'libvo_aacenc' for AAC encoding.[[BR]]
     50Please note it is not recommended to use 'vorbis' for Vorbis encoding.[[BR]]
