Zoom effect based on audio levels using ffmpeg
31 juillet 2021, par FOLLGADI'm trying to create a zoom-in/shake effect based on how loud the audio stream's bass is.


I've realized you can use
showcqt
to get a graph of the sound, but I can't figure out how to pipe that to some zoom function to do zoom based on that.

Any ideas ?

glreadpixels is slower than x11 based screenshot
23 décembre 2013, par quartzI am working on an opengl based simulation application, in which I need to make multiple screenshots in a second. I have tried 2 ways of doing it in my application.
1) use glreadpixels
2) use x11 based screenshot. ex : ffmpeg -f x11grab -s 1024x768 -i :0.0 output.pngI found that second solution is about 3 times faster than first one. I have expected the first solution to be faster. But in practice it is slower. I am curious why glreadpixels is slower ?

FFMPEG : Splice video based on OCR
16 février 2017, par ObeeWnnI am looking for a script that will slice a video depending on the change in a number in the upper left hand corner of the video. This would take 10 seconds leading up to #1, and 10 seconds afterwards. Then again 10 seconds leading up to #2, 10 seconds afterwards, and so on.
I am looking to combine this with a script that does this based on audio peaks. Really, I’m trying to automatically highlight a video based on a number of factors :
Audio peaks
OCR on # on screen
Graphic/movement intensity
