  • Architecture of video-based service for mobile phones

    27 juin 2015, par David Azar

    I guess this is more of a conceptual question than a technical one.

    I’m trying to figure out the best way to upload short videos to a server and also be able to download them and watch them on both Android and iOS.

    Lets focus on Android for the moment.

    I’ve done some experiments, and my results have been :

    • I’m able to compress 12-14MB video down to 500KB using FFMPEG lib with pretty good results in quality, but it takes about 12 seconds.

    • Next, im uploading those videos to my Parse backend as ParseFile to store them.

    • Finally, i can download them and watch them with no problem using a VideoView widget.

    Now, for the tests i’ve been running, these are great results. But i want to see if there is a better way to manage and scale all of this.

    My questions are :

    • Is there a better, lighter way to compress video ?

    • Is Parse the right way to go ?

    • How can i stream videos instead of downloading them and storing the on local storage before playing them ? i know this will cause my app to use significant space on disk and i dont want that.

    • How do big companies do this kind of tasks ?

    I’ve heard Amazon S3 is a cool thing for projects like this one, also Google Cloud Platform. I want to understand the best approach before building everything so i can do it the right way and also, provide the absolute best user experience for watching these videos.

  • HTML mp4 Streaming / How can I automatically move the "atom moov" to the beginning of the file ?

    29 octobre 2020, par Einkornwolf

    so I am currently building a Website for School and implemented an Upload-System. Now I want People to be able to watch uploaded Videos. Currently if you try to watch a Video, lets say test.mp4 it takes over a minute to load. I know that using : ffmpeg -i inputvideo.mp4 -movflags faststart -acodec copy -vcodec copy outputvideo.mp4 moves the atom moov to the beginning of the file. And when I manually convert the mp4 using the previous command the file starts playing instantly. But now my problem is, that I don't want to convert each file manually. Is there another way of playing user-uploaded Videos instantly ? Thanks for your help in advance.

    


    I am using this Code, but it has nothing to do with the streaming itself I guess :

    


      <source src="Clap.mp4" type="video/mp4">&#xA;Your browser does not support the video tag. &#xA;&#xA;</source>

    &#xA;

    I also tried to use a js library :

    &#xA;

      &#xA;&#xA;  &#xA;  <code class="echappe-js">&lt;script src=&quot;https://vjs.zencdn.net/ie8/1.1.2/videojs-ie8.min.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;&#xA;&#xA;  &#xA;    &#xA;    &#xA;    

    &#xA; To view this video please enable JavaScript, and consider upgrading to a&#xA; web browser that&#xA; supports HTML5 video&#xA;

    &#xA; &#xA;&#xA; &lt;script src=&quot;https://vjs.zencdn.net/7.8.4/video.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;

    &#xA;

    In both cases I want to play Clap.mp4

  • Error while building ParaView on ubuntu

    21 février 2014, par user3337492

    I´ve got school project that I have to build ParaView and work with it in parallel.

    I am using this guide : http://paraview.org/Wiki/ParaView:Build_And_Install

    I´ve installed all the required packages and now it is time to "Configure ParaView With CMake".

    When I do this recomended code

    mkdir $HOME/projects/ParaView-bin

    cd $HOME/projects/ParaView-bin

    ccmake $HOME/projects/ParaView3

    the terminal shows this :

    CMake Error : The source "/home/kulis/projects/ParaView3/CMakeLists.txt" does
    not match the source "/home/kulis/projects/ParaView/CMakeLists.txt" used to
    generate cache. Re-run cmake with a different source directory.

    so instead of ParaView3 I use ParaView in code : ccmake $HOME/projects/ParaView

    then its possible to set all the variables and compile. But there comes the real problem. When i want to compile it, the terminal shows this error message :

    ERROR ADD_PARAVIEW_VIEW_MODULE called without VIEW_TYPE or VIEW_XML_GROUP

    CMake Error : The following variables are used in this project, but they are set to NOTFOUND.
    Please set them or make sure they are set and tested correctly in the CMake files :
    /home/kulis/projects/ParaView/VTK/IO/FFMPEG/FFMPEG_INCLUDE_DIR
    used as include directory in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avcodec_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avformat_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avutil_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_swscale_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG

    And I do not really know what to do with it.

    I would very much appreciate your help. Thanks
