    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • How can you run an exe as with no window, in the background and being the most efficient use of resources ? [closed]

    18 mars 2013, par Covenant Spokane

    I don't understand the way the windows totally functions so forgive the novice question.

    I want to setup a server running a video processing peogram called FFMpeg. The server will be used at an time to run that command line program in as many instances that the server can handle. I don't want the server to have 100 command windows open while its processing. Can an exe be run as a process or service or something so that it runs without a window and is as efficient as possible.

  • How do I stream remote multiple webcams to multipul users

    29 juin 2016, par Joe Hill

    I need to capture multiple users webcam in the browser and then broadcast it to multiple users this must include a audio and video stream with low and high quality options. Ideally I would not like to use flash but having flash as a fallback is totally fine.

    When the webcam is broadcast to the users this must work on as many platforms as possible.

    I would like some solutions on how to accomplish this, thank you.

  • how does decoder handle media packet lose/out of order/repeat ?

    20 mai 2021, par woder

    this might not be a good question, because it is big, but sincerely, I want to get the overall knowledge of Quality guarantee of video communication：

    


    we know it media packet will lose or out of order or repeat in network realtime communication :

    


    In transport layer, assume that we use rtp to transport media and rtcp to control and feedback ; we can use a buffer to save rtp packets, so we can reorder packets by rtp sequence to solve problem out of order, and filter repeat packets to solve repeat, use rtcp packet to tell the sender that I have lost rtp packet of sequence xxx to solve lose ;

    


    But I have a lot of confusions on decode layer, assume that we have got media packets now and start decoding packets :

    


    Question 1 : We know what if we lose a I frame, the subsequent P/B frames will fail to decode, but what will hapen if we lose a P/B frame ? In h.264, there are inter-predict, what if the lost P/B frame was referred by subsequent frames, does subsequent frames will totally fail to decode ? Or just the inter-predict macroblocks of subsequent frames will fail to decode while intra-predict macroblocks can be decoded then the decoder still can generate a broken frame to us ?

    


    Question 2 : one frame might be consisted of multiple packets, what if we lose a packet, does this frame will totally fail to decode ? Or we can get a broken frame ?

    


    Question 3 : Do media decoders like x264/openh264 will handle packets repeat and out of order ?
