    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • 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 live streaming to Youtube - "Connect streaming software to start preview"

    10 septembre 2019, par Zoltan Fedor

    I have an rtsp feed (H.265) which I am trying to stream to YouTube Live, but whatever I do YouTube Studio just showing the waiting icon with "Connect streaming software to start preview".

    Basically all looks good to me - still, in YouTube Studio only the waiting icon with the "Connect streaming software to start preview" message is visible, not video feed.

    Any ideas ?

  • ffmpeg : audio + image to video : reduce time and space it takes

    9 septembre 2019, par Yashasvi

    Here are the respected sizes of inputs and output :

    inputImage.jpg : 160kb

    inputAudio.mp3 : 380.3kb

    output1.mp4 : 1.3MB

    The size of output video is pretty large as compared to the input audio. This is my first issue.

    Secondly, as you can see, this process takes 30sec, which is too much I think.

    How do I solve this two problems ?

    • reducing the output video file size

    • reducing the time this process takes.

    I’ve gone through numerous online links, including a lot of questions on this forum for the past several hours but still not able to solve this.
    Tried playing with framerate but disturbs the duration of the output video.

    Can someone please help here. Let me know if any other information is needed.

    1 thing that helped me reduce the size of final video from 3MB to 1.2MB was to compress the image that I am using.
