Last modified: 2009-12-31 21:17:25 UTC
More information: http://www.3gpp.org/ftp/Specs/html-info/26-series.htm http://en.wikipedia.org/wiki/Adaptive_Multi-Rate http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC20 http://www.ffmpeg.org/general.html#TOC2 http://wiki.multimedia.cx/index.php?title=AMR 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. 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 and will get the following error after looking for a codec: No packages with the requested plugins found The requested plugins are: Adaptive Multi Rate (AMR) decoder This bug was create to request AMR to be supported by gstreamer. 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

There's both a AMR-WB and AMR-NB plugin in -ugly based on the opencore amr libraries.
Hi David and thank you for the prompt response to this feature request. This was done in hope that this codec may work out of the box (or at least improve the user experience) in our distribution. If you have a different setup as me, please let me know. I am available on freenode and gimpnet should you want to discuss the issue. I find it odd that -ugly should play this codec, since I have 0.10.12-1 of -ugly installed and opening an AMR file still makes gnome-app-install look for a package which will install the necessary codec library. If you can quickly test sample media and confirm this works for you, it would be much appreciated and will help me immensely. Thank you for your time and assistance with this.
Yes, you need at least 0.10.13 of gst-plugins-ugly.
Ahh, thank you Sebastian, that would explain it.
Also note this commit: http://cgit.freedesktop.org/gstreamer/gst-plugins-ugly/commit/?id=cd95215ba94e69489ff9a0b6a1abbfd3e9193423 which was done post-0.10.13.
