Comment (by ahthovaikied):

 From your comment in the other ticket I thought ''sample_fmt'' was only
 the internal sample representation used by FFmpeg, and that actual sample
 size could be anything below that.

 If not, can you confirm that the right algorithm to reliably extract
 sample size is:

 {{{
 if value of 'bits_per_sample' > 0:
   return value of 'bits_per_sample'
 else if value of 'bits_per_raw_sample' is set:
   return value of 'bits_per_raw_sample'
 else extract sample size from 'sample_fmt' string
 }}}

 It looks complex for such simple task but I am looking for something
 reliable that works for every audio format on the surface of the earth.

 Thanks
