  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Save live video stream to a video file

    29 juin 2023, par VISHAL DAGA

    Trying to save live streaming video data into a (any) playable video file.
When I log the data I see the following (Put in comment in below code) :-

    


    axios.get(`http://192.168.1.33`, {&#xA;  responseType: &#x27;stream&#x27;,&#xA;}).then((response)=>{&#xA;  const stream = response.data&#xA;  stream.on(&#x27;data&#x27;, data => {&#xA;    console.log(data);  // <buffer 4c="4c" 28="28" a1="a1" 0c="0c" 0d="0d" 14="14" 0e="0e" e1="e1" 8e="8e" eb="eb" 52="52" 48="48" d0="d0" c0="c0" 4a="4a" 68="68" 7b="7b" 0b="0b" c7="c7" 7c="7c" d2="d2" 55="55" 21="21" 0a="0a" a9="a9" 63="63" 12="12" 96="96" 9b="9b" 00="00" ed="ed" 49="49" 42="42" 1a="1a" 16="16" a4="a4" 1e="1e" 94="94" 50="50" 20="20" a3="a3" d8="d8" d5="d5" 1386="1386" more="more" bytes="bytes">&#xA;                       // <buffer 0d="0d" cb="cb" 4b="4b" f7="f7" 77="77" 36="36" c8="c8" 42="42" 9d="9d" bb="bb" b3="b3" d6="d6" a3="a3" 72="72" 24="24" ff="ff" 00="00" 9e="9e" 29="29" b8="b8" 35="35" a5="a5" 48="48" ad="ad" e2="e2" 11="11" a9="a9" ec="ec" 38="38" 1d="1d" e1="e1" 91="91" 93="93" 73="73" bf="bf" a6="a6" 96="96" 62="62" 26="26" 57="57" f4="f4" a4="a4" 4258="4258" more="more" bytes="bytes">&#xA;                      // ....&#xA;</buffer></buffer>

    &#xA;

    How can I save this data into a video file which can be played ? I am starting to read from live stream at a certain point in time and reading it for few seconds - ex. 5 seconds. I need to have a video of that 5 seconds.

    &#xA;

    Note, when I use the url : http://192.168.1.33, I can see the video on the browser.

  • ffmpeg4android : overlay a video on video with opacity

    21 juin 2016, par LuongTruong

    I am using ffmpeg4android to edit video. Now, I am able to overlay a video on a video by using this command :

    String[] complexCommand = {"ffmpeg","-y" ,"-i", "/sdcard/videokit/in_big.mp4","-strict","experimental", "-vf", "movie=/sdcard/videokit/in_small.mp4 [watermark]; [in][watermark] overlay=main_w-overlay_w-0:0 [out]","-s", "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out.mp4"};

    Now, I want to change the opacity of the video "in_small.mp4" which will be on the top of another video.

    Some useful links :
    using ffmpeg to add overlay with opacity
    ffmpeg overlay video with semi transparent video

    From those links, I know that all_opacity should be the keyword in this case, but I do not know where to put it in the command.

    Please let me know if you have any ideas. Any suggestion would be appreciated !

  • Video upload with carrierwave-video on Rails 4

    15 juin 2017, par MJRLGUE

    it’s been a while I am fighting to play a video in my rails app.

    I am using carrierwave-video, OS : Windows 10 64bits, to stream/show a video in user posts.

    Here is what I did :

    the file video_uploader.rb :

    class VideoUploader &lt; CarrierWave::Uploader::Base
    

    
  include CarrierWave::Video
    
  storage :file
    
  def store_dir
    
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    
  end
    
end

    in the file : _post.html.erb :

    with this line of code : &lt;%= video_tag post.video_url :controls =>true %> I get a blank box with the size of the video.
    and I tried this too and still doesn’t work : &lt;%= video_tag post.video.url if post.video? %>

    I tried ffmpeg too, I installed ffmpeg in my pc and I did include : process encode_video: [:mp4, callbacks: { after_transcode: :set_success } ] in video_uploader.rb file and I get this form error message :

    Video Failed to transcode with FFmpeg. Check ffmpeg install and verify
    video is not corrupt or cut short. Original error : ArgumentError

    Any suggestions please ?
