(And the command to show the available codecs is ffmpeg -codecs)

Hm, interesting. On the non-working box, ffmpeg -codecs shows: D A amrnb Adaptive Multi-Rate NarrowBand D A amrwb Adaptive Multi-Rate WideBand DEA libopencore_amrnb OpenCORE Adaptive Multi-Rate (AMR) Narrow-Band D A libopencore_amrwb OpenCORE Adaptive Multi-Rate (AMR) Wide-Band But how do you explain the difference in the output of -formats? May the problem actually be the amr container and not the codec? Btw on the working boxes, ffmpeg -codecs shows: ffmpeg: missing argument for option '-codecs' :O -- Ticket URL: <https://avcodec.org/trac/ffmpeg/ticket/232#comment:5> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

Now the question is: should that be necessary? If there is any conflict, shouldn't it be detected? Isn't amrnb supposed to be already disabled?

The FFmpeg default native amrnb decoder does NOT support dtx, but the libopencore_amrnb does. By disabling the native one at build time, you force ffmpeg to use the opencore one which supports etc. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/232#comment:7> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
