Il est recommandé dans un premier temps de désactiver le safe_mode, cependant, s’il est correctement configuré et que les binaires nécessaires sont accessibles, MediaSPIP devrait fonctionner correctement avec le safe_mode activé.
Modules spécifiques

$command = "/usr/bin/ffmpeg -threads 1 -y -i 3.mov -vf \"scale=min(1\,gt(iw\,".$width.")+gt(ih\,".$height.")) * (gte(a\,".$aspect.")*".$width." + \

Any ideas of what might be wrong ?
UPDATE : I am pretty sure the error has got something to do with the audio encoding. If I change the
-ab 96kpart to-c:a copy, command executes.
I cannot however use-c:a copybecause for some audio formats the video does not play on mobile devices. Therefore i need the audio settings to be fixed and the same for all videos. -

Xuggler decode H264 packets
18 novembre 2015, par Roy BeanI’m making a test with xuggler, and I’m observing a behavior that I don’t understand.
So I have a H264 frame, stored in a file and I want to decode it.
Bassically I need of the IVideoPicture to then get a buffred image.for the same same packet I need of 10 tries until it retrieved that the IVideoPicture is complete.
this is what ffmpeg does when reads the frame :
Input #0, h264, from 'sample1.jpg':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: h264 (Baseline), yuv420p, 352x288, 25 tbr, 1200k tbn, 50 tbcCan someone of xuggler or ffmpeg knowledge explain what is happen ?
My code bellow :
IContainer container = IContainer.make();
RandomAccessFile aFile = new RandomAccessFile("c://sample1Frame/sample1.jpg","r");
IContainerFormat format = IContainerFormat.make();
format.setInputFormat("h264");

videoCoder = coder;
}
// The timebase here is used as the camera frame rate
videoCoder.setTimeBase(IRational.make(25,1));
// we need to tell the driver what video with and height to use
videoCoder.setWidth(352);
videoCoder.setHeight(288);
