[FFmpeg-user] Decoding g726 audio

[איל חסון]

Tried: ffmpeg -acodec g726 -ac 1 -ar 8000 -i 7011-20171231-073835-Mitzvah5.g726 -f wav -y test.wav
Got: Invalid data found when processing input

Tried: ffmpeg -f s8 -acodec g726 -ac 1 -ar 8000 -i 7011-20171231-073835-Mitzvah5.g726 -f wav -y test.wav
Got: Invalid number of bits 8

Tried: ffmpeg -f g722 -acodec g726 -ac 1 -ar 8000 -i 7011-20171231-073835-Mitzvah5.g726 -f wav -y test.wav
Got: Option sample_rate not found

What are the names of the g726 format?

What did you try?
Command line and complete, uncut console output missing.

FFmpeg does support two (!) raw g726 file formats, the original specification could not decide if the format is little- or big-endian, both are supported.
(The FFmpeg codec is not 100% bit-exact iirc.)
