How to figure out which audio file has more volume level using ffmpeg ?
1er avril 2021, par Mayank ThapliyalI am facing an issue and I don't even know how to describe it technically so I am explaining my issue in plain English (Sorry if someone gets offended)


I have many audio files which I play them in the background in a video. But unfortunately the audio files have different level of volume level :- some audio files have low volume level whereas some audio files have very high level of volume.


Is there any way to reduce the volume level in those audio files where volume level is high (leaving low volume audio files as it is) using ffmpeg. Or something like this


Thank You

FFmpeg dash manifest '-window_size'
14 novembre 2018, par edwinbradfordIn the FFmpeg DASH documentation I don’t understand the purpose of
-window_size
which is explained as :Set the maximum number of segments kept in the manifest.
If my video is 30 seconds long, the GOP size is 4 seconds and the segment length is 4 seconds, what is the meaning and purpose of a parameter to control the maximum number of segments kept in the manifest, when does this parameter need to be used and how do you determine valid values ?
I’m guessing that the stream is being loaded into memory and the number of segments in the manifest controls how much is kept in memory at one time but it’s just a wild guess and I can’t find any further explanation.
I am not live streaming in case it’s relevant.
