21 février 2013, par John KoleszarChanged Paths : Modify /test/convolve_test.cc convolve test : validate 1D filters are 1D Since the 8-tap lowpass filter is non-interpolating, the results are different between applying it at whole-pel values and not. This means that 1D-only versions are requried to be implemented, as opposed to (...)

Fix "Non-monotonic DTS" Warning Caused By asetnsamples Filter
3 septembre 2024, par Harry MuscleI'm using the following complex filter to mute certain parts of an audio file and replace those parts with a beep generated by the
sine
filter :

[0]asetnsamples=n=1,volume=0:enable='between(t,1.57,1.97)+between(t,4.77,5.27)+between(t,5.37,5.87)+between(t,6.37,6.77)'[dippedVocals];sine=d=10:f=1000:samples_per_frame=1,pan=stereo|FL=c0|FR=c0[constantBleep];[constantBleep]atrim=start=0:end=6.77[shortenedBleep];[shortenedBleep]volume=0:enable='between(t,0,1.57)+between(t,1.97,4.77)+between(t,5.27,5.37)+between(t,5.87,6.37)'[dippedBleep];[dippedVocals][dippedBleep]amix=inputs=2



Since I need the locations specified to be exact I'm using the
asetnsamples
filter to set 1 sample per frame to get the highest possible accuracy. However, as soon as I add thisasetnsamples
filter to my filter chain I get thousands of these messages :

Non-monotonic DTS; previous: XXX, current: XXX; changing to XXX. This may result in incorrect timestamps in the output file.



Any idea what's causing that and how to fix it ? BTW, the input file is a ogg file encoded at 44100Hz and the output file is a wav file. Do wav files even contain timestamps ?
