I’m trying to convert an entire presentation to HTML, extracting all the embedded content

  • 0

I’m trying to convert an entire presentation to HTML, extracting all the embedded content etc along the way. I’ve got text, audio, narrations etc all working fine but am having trouble finding out how to export video content.

Im looping through all slides in the presentation, then all shapes on the slide, looking for shapes of type msoMedia. If I find one, then I check it’s MediaType. If it’s ppMediaTypeMovie, then I can find the source file of an externally linked video file using Shape.LinkFormat.SourceFullName, but I can’t for the life of me find out how to access EMBEDDED content.

If I find a shape with a MediaType of ppMediaTypeSound then I can use Shape.SoundFormat.Export to export the audio. Does anybody know of an equivalent for VIDEO shapes? (There’s no Shape.VideoFormat) I’ve spent days looking through every possible data member I can but to no avail.

    It appears Microsoft extract the contents of the media file to a temporary folder anyway, and embedded videos still provide a LinkFormat.SourceFullName to the extracted video:

    ?oshape.LinkFormat.SourceFullName

    C:\Users\Alex\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.MSO\F26FF1D0.m4v

    All that I need to do is fire this file through ffmpeg and I’ve got my video, in the format I want!

    Thanks for your help 🙂
