For a certain conversion I use '-threads 1'. As I understand it ffmpeg
should then only use one CPU. I see that the CPU usage is lower as
without this parameter, but it goes up to 180%. So clearly it is using
at least two CPU's.
Or am I understanding this parameter wrongly?
I am using ffmpeg version 4.3.4-0+deb11u1. (Debian always lags a
little bit behind to be more stable.)
threads can be used for input decoding, output encoding and filtering.
You need to use threads = 1 for all 3 of them.
I see:
-filter_threads
-filter_complex_threads
But nothing for input decoding and output decoding
as always -threads can used twice as other params
before the input file it's *always* an input-param and after it it's an
output-param
