ffmpeg convert video from specified time period slowly
3 septembre 2012, par darkgtFor example :
If I convert video like this :ffmpeg -i demo.avi -ss 00:00:05 -t 00:00:15 test.flv
it's fast
ffmpeg -i demo.avi -ss 00:45:05 -t 00:00:15 test.flv
I have to wait a long time before it actually works.
Any way to fix that ?

ffmpeg - How to change the filter-paramaters depending on time oder framenumber ?
2 mars 2020, par LookAndSeeHallo to all userse and helpers here in this forum ! Thank you, i am new and i have found allready a lot of solutions.
Now I want to ask, if someone can help me :
I have a Movie about 30 seconds made of 1 image.
Now I want to pixelate depending on time or framenumber - every time a litlle bit less.
My code so far :ffmpeg -i in.mp4 -vf scale=iw/n:ih/n,scale=niw:nih:flags=neighbor out.mp4
where n should be the framenumber 1 to 900.
this scould also be t+1 for slower change.the stars are gone - so i mean n times iw:n times ih :
error-massage :
undefined constant or missing ’(’ in ’n’
error when evaluating the expression ’ih/n’
maybe the expression for out_w :’w/n’ or for out_h :’ih/n’ is self-referencing.
failed to configure output pad on paresed_scale_0
error reinitializing filters !
failed to inject frame into filter network : invalid argument
error while processing the decoded data for stream #0:0Do you have some suggestion plaese - Thank you in Advance
