I searched through this forum and tried the proposed way (https://groups.google.com/forum/#!topic/pdfnet-sdk/0-9tjRVpG9U) of extracting video out of a PDF that I created (attached) using Acrobat X Pro.
When I hit the line that reads “int num_annots = page.GetNumAnnots();”, I can see that there is 1 returned. But when I proceeded to execute page.GetAnnot(0) to try to get that annotation, I got null returned back to me. Does the WinRT SDK not support getting RichMedia annotation? I used the CosEdit tool to ensure that the PDF I’m working with does have the mp4 file that I embedded.
Also, I noticed that the WinRT SDK doesn’t have the StdFile object in the pdftron.Filters namespace. Is StdFile not ported to WinRT?
