Details

ffmpegconv converts MP3 or WAV to various Telephony Codec formats.
According to AVM the supported input formats are[1]:

  • WAV format: 8000 Hz, 16-bit, mono (recommended)
  • MP3 format: Fixed data rate, 128 kbit/s, 44.1 kHz, stereo

ffmpegconv is an AVM enhanced stripped down FFmpeg subset and can perform Transcoding, Resampling and Normalizing.
Further stripped down FFmpeg parts used by ffmpegconv are libavcodec.so, libavformat.so and libavutil.so.

AVM added libresample.so for Resampling and Normalizing, libmscodex.so for Speex support and the *optionally loaded*
(no dependency) libceltcodec.so for CELT support.

ffmpegconv requires playerd_tables to be run once before using it. It creates the required ffmpeg_mp3.tables.

ffmpegconv convert MP3 / WAV to various formats

       -i <MP3/WAV-infile>
       -o <outfile>
       --limit <kbyte>

       --type 0: PCM (resampled to 16 KHz) 
              1: G.722 (default)
              2: PCM (original) mono 
              3: PCM (original) 
              4: PCM (resampled to 8 KHz)

Examples

MOH samples are used by telefon and always PCMA encoded, sample rate and limit depend on available storage space.
Simplified from moh_upload:

ffmpegconv -i <file> -o fx_moh --limit 32 --type 6
ffmpegconv -i <file> -o fx_moh --limit 480 --type 8
ffmpegconv -i <file> -o fx_moh --limit 32 --type 7
ffmpegconv -i <file> -o fx_moh --limit 480 --type 9

TAM voice prompts are used by libtam.so for telefon and always Speex encoded.
Simplified from tam_upload_voice_prompt:

ffmpegconv -i tam_upload -o tam_upload.spx --type 5

Ringtones are stored in the Phonebook for FRITZ!Fon and are either CELT or G.722 encoded.
Simplified from pbd_upload_ringtone:

ffmpegconv -i upload.mp3 -o <file>.celt --limit 240 --type 10 +n
ffmpegconv -i upload.mp3 -o <file>.g722 --limit 240

dect_ringtone_conversion.sh also converts Ringtones.

Source

The names of source files compiled into an executable often help to understand function blocks (and show gaps in the docs).
