  • 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.

  • Leading Google Analytics alternative, Matomo, parodies Christopher Nolan blockbuster ahead of the UA sunset

    4 juillet 2023, par Erin — Press Releases

    Wellington, New Zealand, 4 July 2023 : In the world of online data, Google Analytics has long reigned supreme. Its dominance has been unquestioned, leaving website owners with little choice but to rely on the tech giant for their data insights. However, a new dawn in web analytics is upon us, and Matomo, the leading alternative to Google Analytics, is seizing a unique opportunity to position itself as the go-to provider. In a bold move, Matomo has launched a parody trailer, “Googleheimer,” humorously taking a satirical swipe at Google in the style of the upcoming Oppenheimer biopic by Christopher Nolan.

    Capitalising on a time-bound decision

    With an important decision looming for marketers and web specialists who need to switch analytics providers by July 1st, Matomo has found the perfect window to capture their attention.

    The urgency of the situation, combined with the high intent to switch providers, sets the stage for Matomo to establish itself as the leading alternative analytics platform of choice.

    Matomo’s parody trailer addresses the frustrations of GA4 head-on by highlighting the issues and the uncertainties caused by the sunset of Universal Analytics in humorous satire with lines such as :

    “But we’re keeping everyone’s data, right ? Right ?? …RIGHT ?!”

    Riding on the coat tails of this summer’s anticipated blockbuster from Christopher Nolan, Matomo openly points at the downsides of GA4, and reflects many frustrated marketers pain points in an entertaining way. Beneath the comedic and satirical tone lies the message that users have choices, and no longer need to surrender to the behemoth incumbent.

    Matomo was founded to challenge the status quo and provide a solution for those who believe in privacy and in ethical analytics, and who prefer that their customer data not be concentrated in the hands of just a few corporations.

    Watch the full trailer here.

    More on Google Analytics changes



    A new dawn in web analytics is upon us, and Matomo – the leading alternative to Google Analytics – is here for it. After 20 years, Google is blowing up Universal Analytics (or GA3) – and taking your data with it. Inspired by Christopher Nolan’s upcoming biopic about physicist J. Robert Oppenheimer and the making of his atomic bomb (also known as “The Manhattan Project”), this parody trailer openly points to Google and draws the comparison in humorous satire. GA4 comes with a new set of metrics, setups and reports that change how you analyse your data.

  • ffmpeg background worker runs in debug but not in application

    2 novembre 2019, par Purgitoria

    My application has a function of taking captured images and using an FFmpeg background worker to stitch these into a time-lapse video. The GUI has some simple options for video quality and for the source folder and output file. I had an older version of my application written in VB.NET and that worked without issue but I am rewriting in C# as it supports additional capture and filter capability in the image processing but am having real trouble figuring out what is wrong with this function.

    I have tried relocating FFmpeg to different locations just in case it was a permissions issue but that had no effect and I also tried to put the function in a "try" with a message box to output any exceptions but I got different errors that prevented me from compiling the code. When I run the application from within VS 2015 in the debugging tool the function works just fine and it will create a video from a collection of still images but when I build and install the application it does not work at all and I cannot see what is causing it to fail. In the options for ffmpeg I used the -report to output a log of what happens in the background worker and in debug, it creates this log but from the application, it does not so I presume it is not even running ffmpeg and going straight to the completed stage of the function.

    Function startConversion()

       CheckForIllegalCrossThreadCalls = False
       Dim quality As Integer = trbQuality.Value
       Dim input As String = tbFolderOpen.Text
       Dim output As String = tbFolderSave.Text
       Dim exepath As String = Application.StartupPath + "\\bin\ffmpeg.exe"
       input = input & "\SCAImg_%1d.bmp"
       input = Chr(34) & input & Chr(34)
       output = Chr(34) & output & Chr(34)

       Dim sr As StreamReader
       Dim ffmpegOutput As String

       ' all parameters required to run the process
       proc.StartInfo.UseShellExecute = False
       proc.StartInfo.CreateNoWindow = True
       proc.StartInfo.RedirectStandardError = True
       proc.StartInfo.FileName = exepath
       proc.StartInfo.Arguments = "-framerate 25 -start_number 0 -pattern_type sequence -framerate 10 -i " & input & " -r 10 -c:v libx264 -preset slow -crf " & quality & " " & output
       proc.Start()

       lblInfo.Text = "Conversion in progress... Please wait..."
       sr = proc.StandardError 'standard error is used by ffmpeg
       btnMakeVideo.Enabled = False
       Do
           ffmpegOutput = sr.ReadLine
           tbProgress.Text = ffmpegOutput
       Loop Until proc.HasExited And ffmpegOutput = Nothing Or ffmpegOutput = ""

       tbProgress.Text = "Finished !"
       lblInfo.Text = "Completed!"
       MsgBox("Completed!", MsgBoxStyle.Exclamation)
       btnMakeVideo.Enabled = True
       Return 0

    End Function

    I checked the application folder and it does contain a subfolder \bin withe the ffmpeg.exe located within the folder so I then used cmd to run an instance of the installed ffmpeg from the application folder and it seemed to be throwing out permissions errors :

    Failed to open report "ffmpeg-20191101-191452.log" : Permission denied
    Failed to set value ’1’ for option ’report’ : Permission denied
    Error parsing global options : Permission denied

    This seems then like it is certainly a permissions problem but where I am not sure. I did not run into this error when using VB.NET so I am wondering where I am going wrong now. I thought perhaps it would just be a write permission in the application folder so I the removed the -report and ran ffmpeg again using cmd from my application folder and it then gave the error

    C :\Users\CEAstro\Pictures\AnytimeCap : Permission denied

    Am I missing something really obvious in my code or is there something more fundamental I have wrong in my setup ?

    I should also add that I tried running ffmpeg via cmd from a copy that was manually placed elsewhere (i used the same file) and that actually worked. For some reason, it seems like it just will not work from wherever my application installs it.

  • ffmpeg concat demuxer dropping audio after first clip

    6 septembre 2020, par marcman

    I'm trying to concatenate a video collection that all should be the same type and format. It seems to work like expected when the original sources are the same type, but when they're different types the demuxer drops audio. I understand that the demux requires all inputs to have the same codecs, but I believe I am doing that already.

    


    This is my workflow (pseudocode with Python-like for loop) :

    


    for i, video in enumerate(all_videos):&#xA;    # Call command for transcoding and filtering&#xA;    # I allow this command to be called on mp4, mov, and avi files&#xA;    # The point of this filter is:&#xA;    # (1) to superimpose a timestamp on the bottom right of the video&#xA;    # (2) to scale and pad the videos to a common output resolution (the specific numbers below are just copied from a video I ran, but they are filled in automatically for each given video by the rest of my script)&#xA;    # (3) To transcode all videos to the same common format&#xA;    ffmpeg \&#xA;        -y \&#xA;        -loglevel quiet \&#xA;        -stats \&#xA;        -i video_<i>.{mp4, mov, avi} \&#xA;        -vcodec libx264 \&#xA;        -acodec aac \&#xA;        -vf "scale=607:1080, pad=width=1920:height=1080:x=656:y=0:color=black, drawtext=expansion=strftime: basetime=$(date &#x2B;%s -d&#x27;2020-08-27 16:42:26&#x27;)000000 : fontcolor=white : text=&#x27;%^b %d, %Y%n%l\\:%M%p&#x27; : fontsize=36 : y=1080-4*lh : x=1263-text_w-2*max_glyph_w" \&#xA;        tmpdir/video_<i>.mp4&#xA;&#xA;&#xA;# create file_list.txt, e.g.&#xA;#&#xA;# file &#x27;/abspath/to/tmpdir/video_1.mp4&#x27;&#xA;# file &#x27;/abspath/to/tmpdir/video_2.mp4&#x27;&#xA;# file &#x27;/abspath/to/tmpdir/video_3.mp4&#x27;&#xA;# ...&#xA;&#xA;&#xA;ffmpeg \&#xA;    -f concat \&#xA;    -safe 0 \&#xA;    -i file_list.txt \&#xA;    -c copy \&#xA;    all_videos.mp4&#xA;</i></i>

    &#xA;

    In my test case, my inputs are 3 videos in this order :

    &#xA;

      &#xA;
    1. a camcorder video output in H.264+aac in a mp4
    2. &#xA;

    3. an iphone video in mov format
    4. &#xA;

    5. an iphone video in mp4 format
    6. &#xA;

    &#xA;

    When I review each of the intermediate mp4-transcoded videos in tmpdir they all playback audio and video just fine and the filtering works as expected. However, when I review the final concatenated output, only the first clip (the camcorder video) has sound. When all the videos are from the camcorder, there is no audio issue—they all have sound.

    &#xA;

    When I output ffmpeg warnings and errors, the only thing that shows up is an expected warning about the timestamp :

    &#xA;

    [mp4 @ 0x55997ce85300] Non-monotonous DTS in output stream 0:1; previous: 5909504, current: 5430298; changing to 5909505. This may result in incorrect timestamps in the output file.&#xA;[mp4 @ 0x55997ce85300] Non-monotonous DTS in output stream 0:1; previous: 5909505, current: 5431322; changing to 5909506. This may result in incorrect timestamps in the output file.&#xA;[mp4 @ 0x55997ce85300] Non-monotonous DTS in output stream 0:1; previous: 5909506, current: 5432346; changing to 5909507. This may result in incorrect timestamps in the output file.&#xA;[mp4 @ 0x55997ce85300] Non-monotonous DTS in output stream 0:1; previous: 5909507, current: 5433370; changing to 5909508. This may result in incorrect timestamps in the output file.&#xA;...&#xA;

    &#xA;

    What might I be doing wrong here ? I'm testing in both the Ubuntu 20.04 "Videos" applications as well as VLC Player and both demonstrate the same problem. I'd prefer to use the demuxer if possible for speed as re-encoding during concatenation is quite expensive.

    &#xA;

    NOTE : This is a different issue than laid out here, in which some of the videos had no audio. In my case, all videos have both video and audio.
