Hi all,
Initially I created a patch for embedding videos into the pdf. But
some of the good suggestions made me to split it into several different
patches.
I added functionality for creating a FileSpec object from the file path. By
embedding its contents in to the pdf. Please give all your suggestions.
Thanks
