  • Error in ffmpeg conversion

    9 avril 2015, par Adam Mo.

    I have a VPS 1G RAM with CentOS 6 i386 minimal installed and installed ffmpeg by ffmpeginstaller.com to setup clipbucket 2.7 in the VPS.
    when I test the ffmpeg by this command :

    wget "http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_surround.avi"
    
ffmpeg -i big_buck_bunny_720p_surround.avi -vcodec libx264 big_buck_bunny_720p_surround-H264.avi

    by following this tutorial I get error

  • How to generate a PDF (1.7) from a MP4 movie (Rich Media annotation) ?

    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 :

    


    


    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
