    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Revert "avcodec/decode : copy the output parameters from the last bsf in the chain...

    12 septembre 2018, par James Almer
    Revert "avcodec/decode : copy the output parameters from the last bsf in the chain back to the AVCodecContext"

    This reverts commit f631c328e680a3dd491936b92f69970c20cdcfc7.
    

    The avcodec_parameters_to_context() call was freeing and reallocating
    
AVCodecContext->extradata, essentially taking ownership of it, which according
    
to the doxy is user owned. This is an API break and has produced crashes in
    
some library users like Firefox[1].
    

    Revert until a better solution is found to internally propagate the filtered
    
extradata back into the decoder context, or a decision is made to change the
    
API.

  • ffprobe json output not working in exec, but works in CMD

    26 novembre 2015, par Nicholas Walker

    I’ve installed ffmpeg on my windows 2008 server.

    I use this string in CMD and i get what i want to get in my

    PHP file :

     ffprobe -v quiet -print_format json -show_format -show_streams "C:\wamp\www\uploads\fc30e528b500b26a391ed4f5ed484310.mp4"

    This is my PHP function i found on another stackoverflow question, it had great feedback so i tested it.

    $file_name = 'fc30e528b500b26a391ed4f5ed484310';
    
$file_ext = 'mp4';
    
$ffprobe = 'C:\\ffmpeg\\bin\\ffprobe.exe';
    
$videoFile = 'C:\\wamp\\www\\uploads\\'.$file_name.'.'.$file_ext;
    

    
$cmd = shell_exec($ffprobe .' ffprobe -v quiet -print_format json -show_format -show_streams "'.$videoFile.'"');
    
$parsed = json_decode($cmd, true);
    
print_r($parsed);

    What is get back is nothing. I also tried using the same function i used with ffmpeg(which i got working for ffmpeg).

    $cmd = $ffprobe.' ffprobe -v quiet -print_format json -show_format -show_streams "'.$videoFile.'" 2>&amp;1';
    
echo shell_exec($cmd);

    This also brings back nothing.

    Any ideas ?

  • convert char buffer (with pcm audio data) to short buffer

    15 décembre 2012, par testCoder

    I have char pAudioBuffer buffer which i got from function ffmpeg :

    int len = avcodec_decode_audio3(av_codec_context,
    
            (int16_t *) pAudioBuffer, &amp;out_size, &amp;packet);

    I know that audio format is two bytes per sample, i need to convert every two bytes to short value, i have tried to use code snippet below, but i often got zero instead of short value :

    int shortBufIndex = 0;
    
for (int i = 0; i &lt; (out_size); i += 2) {
    
    char b1 = pAudioBuffer[i];
    
    char b2 = pAudioBuffer[i + 1];
    
    short sample = atoi(&amp;b1) + atoi(&amp;b2);
    
    shortBuffer[shortBufIndex] = sample;
    
    shortBufIndex++;
    
    LOGI("BUFFER_ITEM=&#39;%d&#39;", sample);
    
}

    What i'm doing wrong, how to convert every two bytes in char buffer to short and and back.

    UPDATE :

    system's byte order is LITTLE_ENDIAN i have test it like this : Endianness of Android NDK

    How can i convert every two bytes in buffer to sample of short type and back. Please can you provide any code sample.
