  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • How to embed an MP4 inside a PDF ?

    19 août 2020, par malat

    I am a happy user of img2pdf. This tool does the minimal amount of work to put a series of JPEG 2000/JPEG/PNG images into a PDF "enveloppe". However I am now faced with a new challenge : embed a MP4 file into a PDF "enveloppe".

    


    I see that commercial tool can do it, as seen at :

    


    


    Here is one such sample PDF file (no Flash required on windows in this sample) :

    


    


    It seems to have been introduced in ISO 32000-1 (PDF 1.7 Extension Level 5)

    


    I am looking for a solution which will use the Rich Media annotation inside the PDF stream.

    


    There are dozen of duplicated questions on superuser/stackoverflow, which all pretty much refer to imagemagick/convert command line tool. But in my case, convert expand the images into a multi-page PDF (which is not my desired behavior) :

    


    $ convert input.mp4 output.pdf
$ pdfinfo output.pdf

  • FFmpeg trim filter fails to use sexagisimal time specification and the output stream is empty. Is it a bug and is there a fix ?

    29 novembre 2020, par Link-akro

    With ffmpeg the trim filter (or its audio variant atrim) malfunctions whenever i try to write a sexagesimal time specification for the boundaries or duration parameters of the filter : the result is always an empty stream.

    


    According to the documentation i already linked, which was generated on November 26, 2020 so far, the time duration specification should be supported.

    


    


    start, end, and duration are expressed as time duration specifications

    


    


    Quote of the spec.

    


    


    [-][HH :]MM:SS[.m...]

    


    


    


    [-]S+[.m...][s|ms|us]

    


    


    I am working in a Windows_10-64bit and scripting in its CMD.exe command-line, should it matter.

    


    Here is an instance of trimming a video stream out of a media file with hardcoded value for simplicity. The audio is retained unless i use atrim as well.
We may or may not append the setpts filter as recommended in the documentation henceforth setpts=PTS-STARTPTS if we want to shift the stream to start at the beginning of the cut range.

    


        ffmpeg -i sample-counter.mp4 -vf "trim=start=start='1:2':end='1:5'" sample-counter-trimmed.mp4


    


    If i use decimal it works as intended.

    


        ffmpeg -i sample-counter.mp4 -vf "trim=start=start='2':end='5'" sample-counter-trimmed.mp4


    


    This is the banner of my ffmpeg build. We may see it is the latest build by gyan.dev at the moment i post this.

    The incorrect stream is always reported as 0kB weight in the output of ffmpeg. I confirmed with ffprobe Movie_Countdown-trim-2-5.mov -show_streams -show_entries format=duration that the incorrect stream is duration zero.

    


    Should i report it as a bug ? Is there some correction or workaround ?

    


    I would rather a solution with the trim filter itself, but if not possible a CMD batch scripting.
We should not need a different filter like select or seeking option like there are tutorials and questions/answers everywhere already. Scripting would be straight-forward in a proper *nix shell+distrib and taught everywhere so it is not worth caring while CMD answers on the other hand are rare so a scripting workaround for CMD would have some microcosmic worth since making one is considerably less straight-forward than a shell with modern mathematics and parsing abilities built-in or packaged.
