Hi there

I am doing audio converting and use ffmpeg.

I looked into a ffmpeg sample program  demuxing_decoding.c

and inside decode_packet function


size_t unpadded_linesize = frame->nb_samples * av_get_bytes_per_sample((AVSampleFormat)frame->format);
fwrite(frame->extended_data[0], 1, unpadded_linesize, audio_dst_file);

I would like to convert audio packet to DBFS (Decibels full scale).

Could someone help me?
I will appreciate any suggestion from you.

Thank in advance.
