Videos in PDF.js

[count0]

Are there any plans to include support for embedded videos in PDF files?

This is currently unsupported in any other PDF viewers in GNU/Linux, so it would be a significant contribution.

13.2.4 Media Clip Objects from PDF32000:2008? If codec is supported by browser, then it will be possible. Could you post link(s) to the existing PDF(s) with embedded videos?

Here is an example: http://dante.ctan.org/tex-archive/macros/latex/contrib/movie15/doc/overlay-example.pdf

There's no video showing in both Preview and the Chrome PDF Viewer.

AFAIK video support only works with Acrobat Reader in windows, perhaps also in MacOS but I'm not sure.

The latest okular on Linux (with the help of libpoppler) also displays the embedded files properly. It would be great to have this support for audio/video in codecs supported by the browser.

Is this even used by anyone? I suppose so, since there's people showing interest, but it sounds like the kind of feature that only serves as an excuse to sell you a newer version of Acrobat, but no one really needs.

I guess the developers will not give this any priority, unless there's proof that more than a handful of people use it in real life. So if someone really wants to see this implemented, the fastest way would be to implement it yourselves, and make a Pull Request. But like Yury said, unless the embedded media happens to be supported by the browser, I don't see it happening.

I often make presentations with latex/beamer with the movie15 package that creates these PDF files. So to me this would be a very nice feature to have. I don't really use acrobat after libpoppler supports it now though :)

Yes, I agree with happyalu. Embedded videos in presentations is also what I had in mind. I do think it would be a very useful feature.

Our lecturer gives us a PDF presentation which contains embedded video, but Okular does not support this. The PDF was created with Adobe PDFMaker 10.1 for PowerPoint. According to https://bugs.kde.org/show_bug.cgi?id=311457 (not my bug/file), Adobe embeds Flash (!!) in the PDF.

I've uncompressed the example in https://github.com/mozilla/pdf.js/issues/2787#issuecomment-13993100 pdftk overlay-example.pdf output doc.unc.pdf uncompress http://pastebin.com/M7CSvg0Q

I've added a console message

console.log(subtype, ref);

https://github.com/mozilla/pdf.js/blob/master/src/shared/annotation.js#L253 And got from the first page:

FileAttachment Object { num=15, gen=0}
Screen Object { num=16, gen=0}

Does it means that the first annotation is the actual video data and the second annotation displays it? How can I get the video binary data and insert it in a video tag? How can I place the video tag in the right position?

[yurydelendik]

Screen has something:

• dict.get('A').get('R').get('C').get('D').get('EF').get('F') is a binary stream
• or, dict.get('A').get('R').get('C').get('D').get('F') is a url

Fixed by #5450

@yurydelendik Unfortunately, the link does not work anymore. Here you can see the archived version but I am unable to download the pdf files :https://web.archive.org/web/20150228104639/http://acroeng.adobe.com/wp/?page_id=61

Previous work for this has been done in #4376, which continued in #5450, but both were closed because the solution was not complete. Anyone willing to work on this feature may create a new pull request and perhaps reuse parts of those pull requests.

I recommend to first work on the core layer in src/core/annotation.js: create a new class for video annotations and parse the data to prepare it for the display layer. Make sure that this works as expected and provide unit tests. Then, a second pull request could implement video annotations in the display layer in src/display/annotation_layer.js, which actually makes the annotations appear on the rendered document. Doing it this way, in small chunks, makes implementation, testing and review easier than if it were done in one big pull request.

In my opinion this should work with the HTML5 <video> tag as much as possible.

can anyone help me with the architecture of PDF.js . I'm working on project so if anyone can help me with the architecture of this project. it will be nice of you.
