Hi,
I want to filter a video from pts 0 to 1999 with filter A, then from
2000 to 2199 with filter B, from 2200 with filter A and finally the
whole stream with filter C.
Can one please give me an example for a working command line?
untested:
ffmpeg -i input.mp4 -lavfi
split[a][b];[a]filter_A[c];[b]filter_B[d];[c][d]select=bitor(between(t,0,1999),between(t,2200,10000)),filter_C
out.mp4
I found out, that the 'between(t,a,b)' should be surrounded by colons.
But anyway the reality is more complex. I have to use 3 different
filters. So I tried:
ffmpeg -i input.mp4 -filter_complex
"split[a][b][c];[a]filter_A[d];[b]filter_B[e];[c]filter_C[f];[d]select='between(t,0,1999)';[e]select='between(t,2000,2199)';[f]select='between(t,2200,10000)'",filter_D
out.mp4
Sorry that my example was wrong. Please have a look at the
"streamselect" filter instead of "select".
However the problem might be easier to solve if your filters A, B and C
have timeline support with "enable" option. Use this command to find out
if your filters have timeline support:
ffmpeg -filters
