  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • FFMPEG "Could not allocate memory" Errors through php

    10 décembre 2019, par Applepiee

    I’ve tried to find a solution online for days now but cannot find any solution.

    I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

    All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

    The errors look like this :

  • How to get CMSampleBufferRef from AudioQueueBufferRef

    26 novembre 2015, par arturdev

    I am using a private library which was made for live broadcasting from iPhone.
    In every time of recording each frame it call a delegate function

    void MyAQInputCallback(void *inUserData, 
                              AudioQueueRef inQueue,
                              AudioQueueBufferRef inBuffer,
                              const AudioTimeStamp *inStartTime,
                              UInt32 inNumPackets,
                              const AudioStreamPacketDescription *inPacketDesc) ;

    Now how I can append this inBuffer to my AVAssetWriterInput as usual :

    [self.audioWriterInput appendSampleBuffer:sampleBuffer];

    I think maybe convert AudioQueueBufferRef to CMSampleBufferRef somehow ?

    Thank you.
