13 avril 2011, par kent1

MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
For older browsers the Flowplayer flash fallback is used.
MediaSPIP allows for media playback on major mobile platforms with the above (...)
Support de tous types de médias

10 avril 2011

Contrairement 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) (...)
Support audio et vidéo HTML5

MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

FFmpeg "Unrecognized option" error when trying to merge 2 audio files in Android

20 mars 2017, par Sha

Looked at This and This links to create a command to merge 2 audio files using ffmpeg but it’s not working.

My command :

String input1 = "/storage/emulated/0/jd.m4a "; 

String input2 = "/storage/emulated/0/jd.m4a "; //trying with same audio just to check if it works or not

String filter = "-filter_complex [0:a]volume=0.99[a1];[1:a]volume=0.3[a2];[a1][a2]amerge=inputs=2,volume=1.3,pan=stereo|c0code>

The console output :

From what I can understand is that ffmpeg is unable to split and differentiate the inputs, filter and output from the command, but I tried with a lot of variations, still not working :(

Please help. Looked around a lot but none of the commands is working.

Thanks in advance !

EDIT :
Added -report before -filter_complex and ran. LOG is below AS @Mulvya asked

No output file when converting audio using FFmpeg in Android

18 mars 2017, par Sha

I’m trying to convert m4a audio file to wav using FFmpeg. The code executes fine and gives no error, but I don’t see any output file in my directory.

This is what I am executing :

String[] cmd = {"-y", "-i", "/storage/emulated/0/jd.m4a", "-f","wav" ,"/storage/emulated/0/DCIM/Camera/output.wav"};

And this is what gets printed :

WMAV2 and FFMPEG on iPhone

14 avril 2012, par user1333656

Recently, I try to decode audio files on iPhone by using ffmpeg.
Most audio formats are decoded properly but WMAV2 isn't.
The decoded file(raw data) can be imported to sound editor like AUDACITY and it is playable but not clear and different with the original track.
Is this related to ARM floating point ???

Someone said VBR WMAV2 could cause this kind of prob.
Can any body give me any clue for this prob ??

IOS 5.1
XCODE 4.3.1
OSX 10.7.3
ffmpeg 0.10.1
