Re: 3gp + vlc

Here, with the Kubuntu 9.10


3gp

> 3gp wiki

...
The 3GP file format stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC, HE-AAC v1 or Enhanced aacPlus (HE-AAC v2)...

VLC

The > VLC Features Formats is telling:

Audio Codecs

Audio Codecs Status
Name FOURCC Decoder Encoder library Comment
...
AMR samr Yes Yes ffmpeg + libamrnb + libamrwb RECOMPILE VLC for this Speech codec
...

The libamrnb & libamrwb are in the > Medibuntu.


Extra / unrestricted codecs

The ffmpeg has restricted and unrestricted versions of the codecs/device/postprocessing libraries.

> FFmpeg

Legal status of codecs
...
Most GNU/Linux distributions include a stripped version of FFmpeg only including
certain codecs to avoid legal complications, instead providing such software at unofficial repositories...

Unrestricted:

libavcodec-extra-52
libavdevice-extra-52
libavformat-extra-52
libavutil-extra-49
libpostproc-extra-51
libswscale-extra-0

Using > Medibuntu versions of the unrestricted libraries.

1) Installing the "extra" versions.

2) Downloading a 3gp clip from the > Free 3gp Video: (dancing-skeleton.3gp)

Audio
ID : 2
Format : AMR
Format/Info : Adaptive Multi-Rate
Format profile : Narrow band
Codec ID : samr

3) Playing it with the VLC/Kaffeine/SMPlayer - the audio is playing.

Re: 3gp + vlc

sorry for late reply.. i had forgotten about problem of 3gp in between
@rog: i added medibuntu repository by running the command as suggested on medibuntu site in konsole

sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get --quiet update && sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring && sudo apt-get --quiet update

still after playing file in vlc it is giving me this warning and sound is not playing:

VLC does not support the audio or video format "samr". Unfortunately there is no way for you to fix this.

what step did i miss?

one more question.. what is the need of unrestricted libraries? will adding a line in sources.list file suffice?

Do you have the ffmpeg + libamrnb3 + libamrwb3 ?:

sudo apt-get install ffmpeg

+

sudo apt-get install libamrnb3 libamrwb3

Medibuntu (1) in the sources and installation of the "extras"

sudo apt-get install libavcodec-extra-52 libavdevice-extra-52 libavformat-extra-52 libavutil-extra-49 libpostproc-extra-51 libswscale-extra-0

That will replace (remove) the non-extras:

The following extra packages will be installed:
apport-hooks-medibuntu libdirac0c2a libopenjpeg2
The following packages will be REMOVED:
libavcodec52 libavdevice52 libavformat52 libavutil49 libpostproc51
libswscale0
The following NEW packages will be installed:
apport-hooks-medibuntu libavcodec-extra-52 libavdevice-extra-52
libavformat-extra-52 libavutil-extra-49 libdirac0c2a libopenjpeg2
libpostproc-extra-51 libswscale-extra-0
0 upgraded, 9 newly installed, 6 to remove.

(1) The Ubuntu repositories also have the extras but the Medibuntu has traditionaly enabled more...

Re: 3gp + vlc

i restarted my computer after medibuntu repository was added. and it worked.. now the warning in vlc is gone.. and 3gp with audio works fine..
sorry.. i was bit impatient to post that it is not working.

@Rog131:

Code:
sudo apt-get install ffmpeg
+
Code:
sudo apt-get install libamrnb3 libamrwb3

all were updated.. i just checked..
and this only worked like a charm i guess
thanks...
