If the option in question indeed is available then it’s undocumented. The ffprobe help reveals the following usage:
Global options (affect whole program instead of just one file): -loglevel loglevel set logging level -v loglevel set logging level -report generate a report -max_alloc bytes set maximum size of a single allocated block -y overwrite output files -n never overwrite output files -ignore_unknown Ignore unknown stream types -filter_threads number of non-complex filter threads -filter_complex_threads number of threads for -filter_complex -stats print progress report during encoding -max_error_rate maximum error rate ratio of errors (0.0: no errors, 1.0: 100% errors) above which ffmpeg returns an error instead of success. -bits_per_raw_sample number set the number of bits per raw sample -vol volume change audio volume (256=normal) There’s bits_per_raw_sample but no bits_per_sample. And the same is true for the video options - no bits_per_sample. > On 5 Aug 2020, at 12:08, Paul Blakeman via ffmpeg-user > <[email protected]> wrote: > > > > Input #0, wav, from 'Lee.wav': > Metadata: > encoded_by : Pro Tools > originator_reference: 7iGQ3S9p7mlaaaGk > date : 2020-07-23 > creation_time : 14:05:55 > time_reference : 158865370 > Duration: 00:04:15.83, bitrate: 1422 kb/s > Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, 2 > channels, s16, 1411 kb/s > bits_per_sample=16 > bits_per_raw_sample=N/A > > > When I try on an audio file created with ProTools > > ffprobe -show_streams -show_format Lee.wav | grep bits > > On an audio file “bits_per_sample” is what you are after > > >> On 5 Aug 2020, at 08:41, Paul B Mahol <[email protected]> wrote: >> >> On 8/5/20, scrutinizer <[email protected]> wrote: >>> The file is AIFF, 24bit/96kHz.
