** Description changed: Binary package hint: ffmpeg - Mplayer and Totem/gstreamer cannot play *.amr audio files - and also play only video part of widely used Nokia phone's *.3gp files - (due to its audio part is in AMR NR format). - FFmpeg which is used in mplayer and totem for codecs can - be build with AMR support as described in http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html#SEC20 + 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. 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
