Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

(Dés)Activation de fonctionnalités (plugins)
18 février 2011, parPour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".
MediaSPIP est fourni par défaut avec l’ensemble des plugins dits "compatibles", ils ont été testés et intégrés afin de fonctionner parfaitement avec chaque (...) -
Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

Audioqueue try to read ADPCM sound
4 septembre 2013, par KamaxI try to read a .asf stream with FFMPEG and the audio part is ADPCM IMA WAV codec.
The sound i hear when i hear something is only noise. I suppose my AudioStreamBasicDescription are wrong. How can i get the correct values ?
From ffprobe i have this :
[STREAM]
index=1
codec_name=adpcm_ima_wav
codec_long_name=ADPCM IMA WAV
codec_type=audio
codec_time_base=1/8000
codec_tag_string=[17][0][0][0]
codec_tag=0x0011
sample_rate=8000.000000
channels=1
bits_per_sample=4
r_frame_rate=0/0
avg_frame_rate=250/41
time_base=1/1000
start_time=0.000000
duration=N/A
[/STREAM]and
Stream #0.1: Audio: adpcm_ima_wav, 8000 Hz, 1 channels, s16, 32 kb/s
my code for the moment is :
asbd.mSampleRate = 8000;
asbd.mFormatID = kAudioFormatAppleIMA4;
asbd.mBytesPerPacket = 34;
asbd.mFramesPerPacket = 64;
asdb.mbitsPerChannel = 1;All the rest is to 0 (flags, byte per frame, bits per channel, reserved).
Edit :
I just find that the codec code 17 is maybe for kAudioFormatDVIIntelIMA and not kAudioFormatAppleIMA4. Can someone confirm this ?
This is from ffprobe :
[PACKET]
codec_type=audio
stream_index=1
pts=11200
pts_time=11.200000
dts=11200
dts_time=11.200000
duration=164
duration_time=0.164000
size=656.000000
pos=1171105
flags=K
[/PACKET]Is the size 656 for mBytesperpacket ?
With this value and the half 328 for mFramesPerPacket i can hear something but it's not continuous and has a lot of noise.
Please help !

Anomalie #3607 : Problème de compatibilité avec mysql 5.7 pour SPIP 3.1
26 avril 2016, par Guillaume FahrnerLe format est correct, la valeur ne convient par contre pas. La changer parait suffisant :
https://github.com/concrete5/concrete5/issues/3185 :
The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in ’YYYY-MM-DD HH:MM:SS’ format. The supported range is ’1000-01-01 00:00:00’ to ’9999-12-31 23:59:59’.

Encoding Exception during Transcode with audio files
6 mai 2016, par Hakop ZakaryanI am attempting to transcode using an FFMPEG Wrapper Library called JAVE on Mac OSX 10.11.3 using Eclipse 4.50
My Converter.java class looks something like this :
package matador;
import it.sauronsoftware.jave.AudioAttributes;
import it.sauronsoftware.jave.EncodingAttributes;
import it.sauronsoftware.jave.EncoderException;
import it.sauronsoftware.jave.InputFormatException;
import it.sauronsoftware.jave.Encoder;
import java.io.*;
public class Converter {
public static void main(String[] args) throws InputFormatException, EncoderException {
File source = new File("Classic.m4a");
File target = new File("target.mp3");
AudioAttributes audio = new AudioAttributes();
audio.setCodec("libmp3lame");
audio.setBitRate(new Integer(128000));
audio.setChannels(new Integer(2));
audio.setSamplingRate(new Integer(44100));
EncodingAttributes attrs = new EncodingAttributes();
attrs.setFormat("mp3");
attrs.setAudioAttributes(audio);
Encoder encoder = new Encoder(new MyFFMPEGExecutableLocator());
try {
encoder.encode(source, target, attrs, null);
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (InputFormatException e) {
e.printStackTrace();
} catch (EncoderException e) {
e.printStackTrace();
}
}
}The problem I am running into is that with specific audio files (regardless of format) give me this EncoderException :
it.sauronsoftware.jave.EncoderException: Metadata:
at it.sauronsoftware.jave.Encoder.encode(Encoder.java:863)
at matador.Converter.main(Converter.java:32)I have looked through Encoder.java and the EncoderException on line 863 is this specific code :
} else if (!line.startsWith("Output #0")) {
throw new EncoderException(line);I have been unable to figure out why this may be occurring but specific audio files (WAV/AAC/etc) do encode yet a majority just give this exception.
Thank you for the help !
