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://samples.mplayerhq.hu/A-codecs/amr/
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->gnome-app-install gives the following error after looking for a 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
