  • La sauvegarde automatique de canaux SPIP

    1 April 2010, by

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Encoding and processing into web-friendly formats

    13 April 2011, by

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • Getting accurate time from FFMPeg with Objective C (Audio Queue Services)

    2 April 2012, by Winston

    My iPhone app plays an audio file using FFMPeg.

    I'm getting the elapsed time (to show to user) from the playing audio (in minutes and seconds after converting from microseconds, given by FFMPeg) like so:

    AudioTimeStamp currentTimeStamp;
    
AudioQueueGetCurrentTime (audioQueue, NULL, &currentTimeStamp, NULL);
    

    
getFFMPEGtime = currentTimeStamp.mSampleTime/self.basicAudioDescription.mSampleRate;
    

    
self.currentAudioTime = [NSString stringWithFormat: @"%02d:%02d",
    
                            (int) getFFMPEGtime / (int)60000000,
    
                            (int) ((getFFMPEGtime % 60000000)/1000000)];

    Everything works fine, but when I scrub back or forward to play another portion of the song, the elapsed time will go back to zero, no matter the current position. The timer will always zero out.

    I know I'm suposed to do some math to keep track of the old time and the new time, maybe constructing another clock or so, perhaps implementing another callback function, etc... I'm not sure what way I should go.

    My questions are:

    1) What's the best approach to keep track of the elapsed time when going back/forward in a song, avoiding the clock to always going back to zero?

    2) Should I look deeply into FFMPeg functions or should I stick with Objective-C and Cocoa Touch for solving this problem?

    Please, I need some advices/ideas from experienced programmers. I'm stuck. Thanks beforehand!

  • How does one encode a series of images into H264 using the x264 C API?

    23 September 2016, by Rella

    How does one use the x264 C API to encode RBG images into H264 frames? I already created a sequence of RBG images, how can I now transform that sequence into a sequence of H264 frames? In particular, how do I encode this sequence of RGB images into a sequence of H264 frame consisting of a single initial H264 keyframe followed by dependent H264 frames?
