Bug Description
Binary package hint: ffmpeg

AMR (Adaptive Multi-Rate) is a vocoder employed in low-bitrate applications like mobile phones. There are narrowband and wideband variants of this codec. AMR was adopted as the standard speech codec by 3GPP in October 1998 and is now widely used in GSM and UMTS. FFmpeg should be able to decode AMR with OpenCORE AMR libraries (package: libopencore-amrnb0) but does not.
Example Media:
http://
Current result:
Audio does not play.
Expected result:
Play audio. If codec is not installed, suggest proper package. Expect codec to be supported.
There is no codec pack for gstreamer or ffmpeg to play this type of file. The average user will do the following.
totem->gstramer->no codec->
No packages with the requested plugins found
The requested plugins are:
Adaptive Multi Rate (AMR) decoder
VLC reports the following error when opening the video:
No suitable decoder module:VLC does not support the audio or video format "samr". Unfortunately there is no way for you to fix this.
This bug was create to request AMR to be supported by gstreamer and ffmpeg. If this is not possible due to legal issues or other roadblocks, please define what the issue is with supporting this codec.
Tested on:
i386, Ubuntu Desktop 9.10, Linux 2.6.31-15

While having a look at the linked zip file you pointed to, I found this in the included word document:

No part may be reproduced except as authorized by written permission.
The copyright and the foregoing restriction extend to reproduction in all media.
Sorry, this means we cannot include it into our ffmpeg tree.
I suggest you work together with ffmpeg upstream to get a free implementation of AMR into ffmpeg.
