  • Covert images into video

    16 août 2016, par Disha Shukla

    I have some images in the folder. I want to convert all images into videos. But the problem is that when the resolution is different it shows the error. I don’t want to stretch the images in the video. I just want to keep image size as it is. But it shows this error.

    My Command :

    ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 -shortest -c:v libx264 -r 30 -vf "scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):ow/(16/9):(ow-iw)/2:(oh-ih)/2" -aspect 16:9 -pix_fmt yuv420p out.mp4 -y

    Logs :

    Is there any way to keep resolution as it is and make a video of all images ?

  • 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
