Comment (by ahthovaikied):

 Replying to [comment:3 cehoyos]:
 > Iirc, {{{bits_per_sample}}} is codec-specific and mostly meaningful for
 PCM and ADPCM codecs.
 So what is the reliable, portable (across formats) way to get audio bits
 per sample ?
 * {{{bits_per_sample}}} is 0 for most files
 * {{{bits_per_raw_sample}}} seems correct after applying your patch for
 the 24bits example, but not always available (ie with a 16bit file)
 * {{{sample_fmt}}} is unrelated ?
