Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.
The code of this (...) -
Contribute to translation
13 avril 2011You can help us to improve the language used in the software interface to make MediaSPIP more accessible and user-friendly. You can also translate the interface into any language that allows it to spread to new linguistic communities.
To do this, we use the translation interface of SPIP where the all the language modules of MediaSPIP are available. Just subscribe to the mailing list and request further informantion on translation.
MediaSPIP is currently available in French and English (...) -
Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

configure.ac : check for sys/auxv.h before defining FLAC__CPU_PPC
19 septembre 2019, par Peter Seidererconfigure.ac : check for sys/auxv.h before defining FLAC__CPU_PPC
Signed-off-by : Peter Seiderer <ps.report@gmx.net>

Note : One of the buildroot autobuilder provided powerpc toolchains
seem to not provide the sys/auxv.h header file, resulting in a
compile failure (see [1] for details).[1] http://lists.busybox.net/pipermail/buildroot/2019-September/259732.html

Invalid data found when processing file with ffmpeg API
18 septembre 2019, par Timmy KI have an m4a file containing two AAC-encoded audio streams. I want to decode it on Android with the ffmpeg library. However, avformat_open_input() fails with "Invalid data found when processing input".
This file was created (i.e. the audio data encoded) with the same library.
I’ve double-checked the accuracy of the file path I provide to the call.
The file doesn’t appear to be corrupt. It plays with QuickTime player, and ffprobe reports the output below.
I’ve looked at the source in ffmpeg’s utils.c but it’s not clear at which of several points (including nested calls) this invalidity of the data in the file is being decided.

Metadata:
handler_name : SoundHandlerThe call that fails with "invalid data found" is :
if ( (ret = avformat_open_input( &inputFormatContext, filePath, 0, 0)) < 0 )
{
__android_log_print(ANDROID_LOG_DEBUG, "MyTag", "Could not open input file '%s' error %s ", filePath, av_err2str(ret) );
return false;
}I would expect this to "just work" since I encoded and muxed the two audio tracks with the same build of the ffmpeg libraries.
When I built the libraries, I configured the build with :
—enable-decoder=aac,pcm_s16le —enable-encoder=aac,pcm_s16le —enable-demuxer=mp4,wav —enable-muxer=mp4,wav —enable-protocol=file,http
When I iterate through the codecs using av_codec_iterate() and look for supported sample rates I see :
Found codec aac
supported sample rate 96000
supported sample rate 88200
supported sample rate 64000
supported sample rate 48000
supported sample rate 44100
supported sample rate 32000
supported sample rate 24000
supported sample rate 22050
supported sample rate 16000
supported sample rate 12000
supported sample rate 11025
supported sample rate 8000
supported sample rate 7350
Found codec pcm_s16le
Found codec aac
Found codec pcm_s16leEach codec appears twice, which I thought was maybe the encoder and decoder. But I note that only one has any supported sample rates. My test files’ sample rate is 44100.
Any thoughts on what other things I can check for ? I wondered whether I should create and pass an AVInputFormat object explicitly to the call, based upon what I know about the contents of the file. But I don’t know how to construct one.
