From: John Magolske on 16 Apr 2010 15:10 I'm looking for a way to play *.3gp audio files from the command line. Mplayer doesn't seem to work: % Mplayer some-audio-file.3gp [...] Playing some-audio-file.3gp. libavformat file format detected. [lavf] Audio stream found, -aid 0 ========================================================================== Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders Cannot find codec 'libamr_nb' in libavcodec... ADecoder init failed :( ADecoder init failed :( Cannot find codec for audio format 0x726D6173. Read DOCS/HTML/en/codecs.html! Audio: no sound Video: no video Any suggestions for alternate approaches, pointers on how & what to install in terms of a codec, or maybe a way to convert these files (ideally without transcoding degradation)? These audio files were created by the android app "Voice Recorder".

Mmmm, it seems you are missing a codec (AMR). In debian multimedia repo there is one package that provides that codec: *** floating-point Adaptive Multi-Rate (AMR) speech codec http://debian-multimedia.org/dists/stable/main/binary-i386/package/amrnb.php *** That is for lenny 32-bits. Not sure if this will solve the problem :-? OTOH, there are online conversion tools that may also help: http://www.zamzar.com/conversionTypes.php#videos Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

That's why www.debian-multimedia.org exists. Did you Google "linux play 3gp"? If the d-mm.org packages don't work, then Google might. $ apt-cache policy mplayer mplayer: Installed: 1:1.0.rc2svn20100407-0.0 Candidate: 1:1.0.rc2svn20100407-0.0 Version table: *** 1:1.0.rc2svn20100407-0.0 0 500 http://www.debian-multimedia.org unstable/main Packages 100 /var/lib/dpkg/status 1.0~rc3+svn20090405-1+b2 0 500 ftp://ftp.us.debian.org unstable/main Packages $ $ $ apt-cache policy ffmpeg ffmpeg: Installed: 5:0.5.1+svn20100411-0.0 Candidate: 5:0.5.1+svn20100411-0.0 Version table: *** 5:0.5.1+svn20100411-0.0 0 500 http://www.debian-multimedia.org unstable/main Packages 100 /var/lib/dpkg/status 4:0.5.1-3 0 500 ftp://ftp.us.debian.org unstable/main Packages -- Dissent is patriotic, remember? -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

In debian multimedia > repo there is one package that provides that codec: > > floating-point Adaptive Multi-Rate (AMR) speech codec > http://debian-multimedia.org/dists/stable/main/binary-i386/package/amrnb.php I installed the amrnb package from the multimedia repo, but it didn't help. I also installed the OpenCORE AMR libraries to /usr/local/lib as recommended on the Mplayer site: MPlayer can use the OpenCORE AMR libraries through FFmpeg. Download the libraries for AMR-NB and AMR-WB from the opencore-amr project and install them according to the instructions on that page. http://www.mplayerhq.hu/DOCS/HTML/en/codec-installation.html http://sourceforge.net/projects/opencore-amr/ But that didn't help. Also built ffmpeg from source as suggested here: http://ubuntuforums.org/showthread.php?t=178455 and did this: svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg ./configure --enable-libopencore-amrnb --enable-version3 make make install That didn't help either, keep getting "Cannot find codec 'libamr_nb' in libavcodec..." still searching around the www to see what I can find.

Two more hints: 1/ The error message you got was: *** (...) Cannot find codec for audio format 0x726D6173. Read DOCS/HTML/en/codecs.html! *** So follow their wise advice and take a look into that doc file. 2/ Dunno if you already installed the mpeg/ffmpeg versions from "debian- multimedia" repo, as Ron already pointed out. That could be another thing you can test. Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?
