[FFmpeg-user] LPCM in DVD - 44.1/32khz sample rate?

According to this source (vlc) lpcm dvd audio supports lower frequencies like 44100/32000 hz - useful for direct dv transcoding for example https://github.com/videolan/vlc/blob/master/modules/codec/lpcm.c see lines 524, 608 Does this mean that libavcodec/pcm-dvdenc.c can be trivially extend
