Hi,
I used the following command to generate a amrwb .3gp audio file
ffmpeg.exe -i 1.wav -ar 16000 -ab 19.85k -acodec libvo_amrwbenc test1.3gp
But dawr/dawb atom is missing in the clips generated by ffmpeg
I think it should be set as defined below
TS 26.244 define the
struct AMRDecSpecStruc{
Unsigned int (32) vendor
Unsigned int (8) decoder_version
Unsigned int (16) mode_set
Unsigned int (8) mode_change_period
Unsigned int (8) frames_per_sample
}
How we can resolve this issue?
Thank you
Prashantha S
