FFMPEG amix filter volume issue with inputs of different duration
2 août 2016, par cupuycI noticed that
ffmpeg amixfilter doesn’t output good result in specific situation. It works fine if input files have equal duration. In that case volume is dropped in constant value and could be fixed with",volume=2".In my case I’m using files with different duration. Resulted volume is not good. First mixed stream resulted in lowest volume, and last one is highest. You can see on image that volume is increased linearly withing a time.
My command :
ffmpeg -i temp_0.mp4 -i user_2123_10.mp4 -i user_2123_3.mp4 -i user_2123_4.mp4
-i user_2123_7.mp4 -i user_2123_5.mp4 -i user_2123_1.mp4 -i user_2123_8.mp4
-i user_2123_0.mp4 -i user_2123_6.mp4 -i user_2123_9.mp4 -i user_2123_2.mp4
-i user_2123_11.mp4 -filter_complex "[1:a]adelay=34741.0[aud1];

[aud8][aud9][aud10][aud11]
[aud12]amix=inputs=13:duration=first:dropout_transition=0"
-vcodec copy -y temp_1.mp4That could be fixed by applying silence at the beginning and end of each clip, then they will have same duration and volume will be at the same level.
Please suggest how I can use
amixto mix many inputs and ensure constant volume level. -

Mp3 volume up and down within specific parts Android
23 mai 2017, par Vivek BhattI want to alter the volume of an audio file(mp3) within specific parts.
Eg : In 5-10 sec, 10-15 sec, ... 10% of the original volume of audio and in rest for the part 100% of the original volume of audio.
I have tried with FFmpeg by the following command but it’s taking to much time if audio file is of longer durationffmpeg -i "input.mp3" -af volume=0.1:enable=’between(t,5,10)+between(t,5,10)’ -preset ultrafast "output.mp3
Is there any other way around which is bit quick.
Thanks in advance
