Cut detection with ffprobe
2 février 2015, par cronkI’m trying to detect cuts between shots with
ffprobe
. I use the following command :ffprobe -show_frames -of compact=p=0 -f lavfi "movie=test_clip.avi,select=gt(scene\,.4)" > test_clip_cuts.txt
It works just fine, there’s no question. But now I want to detect the cuts in certain range only. Let’s say from 3 to 8 seconds. How I could do that ?
I tried to use
-read_intervals 3%8
but it gave me an error :Could not seek to position 3000000: Invalid argument
Could not read packets in interval id:0 start:3 end:8Command
-read_intervals %+3
(read from the very begining to 3rd second) works, but in weird way - it detects cuts up to 4th second (and over, I guess).So I’m confused. What are those "intervals" and how to use them ? Is it possible to set the range in regular seconds ?
Just in case here is my test clip https://yadi.sk/i/nd-c12mYeQ2nb

vf_tonemap : Fix logic for detecting the maximum peak of untagged sources
25 juillet 2018, par Vittorio Giovaravf_tonemap : Fix logic for detecting the maximum peak of untagged sources
When there is no metadata attached to a frame, take into account both
the PQ and HLG transfers, and change the HLG default value to 10 :
the value of 12 is the maximum range in scene referred light, but
the reference OOTF maps this from 0 to 1000 cd/m² on the ideal HLG
monitor.This matches what vf_tonemap_opencl does.
