Justin Ruggles <[email protected]> added the comment: That is not exactly true. I have been able to generate files that play with the acm codec that are not 32kbps.
ffmpeg -i test.wav -acodec g726 -ac 1 -ab 128k -ar 32000 test_g726.wav mplayer -ac g726 test_g726.wav But FFmpeg can generate many bitrate/samplerate combinations that end up with noisy output when played with the acm codec. Some more testing is needed to determine which combinations are actually valid. ---------- title: g726 encoder only support 32k -> g726 encoder generates invalid files topic: +avcodec ____________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/roundup/ffmpeg/issue491> ____________________________________________________
