Silence, audio level and loudness measurement using FFMPEG

rohit khali
Hi,

Is there a way to know about audio silence, loudness, peak, level as part
of FFMPEG decoding APIs or any other possible solution for the same.

Thanks,
Rohit Khali

By using FFmpeg filtering API. See filters documentation.

Thanks,
All links I came across seem to be based on ffmpeg commands. Ex: ffmpeg.exe
-i .input.ac3  -filter_complex ebur128=peak=true op.wav
It will be great if you can point to some API usage with  filter options.

Regards,
Rohit Khali

this list is for the command line usage. For assistance with API usage,
please refer to libav-user:
https://lists.ffmpeg.org/mailman/listinfo/libav-user

You might also want to look at the examples in the doc/examples/ folder
of the ffmpeg sources.

Regards,
Moritz
