Appears to be a different subject, but most of all, please remember not to top-post on this mailing list. > when calculating the MD5 of an audio WAV file ffmpeg > defaults to 16 bit. No, ffmpeg does not default to "16 bit" or a particular encoder, some muxers default to pcm_s16le for audio if you do not specify a particular encoder. > If the input is 24 bit it is my understanding that > it needs to be explicitly reflected in the command > as -c:a pcm_s24le otherwise the resulting MD5 will > not be accurate. So, yes, if you need accurate md5 for 24 bit input, you have to specify a 24 bit encoder. > Are there comparable variations in the way ffmpeg > processes still image files of different formats, bit > depths, etc., that need to be accounted for in the > command that is used? Typically not: The rawvideo (and the wrapped_avframe) encoder accepts any pix_fmt while the pcm_s16le encoder only accepts s16 input, the pcm_s24le encoder only supports s32 (sic!).
