Bug 64945

Hi Rahul,
The bugzilla platform is tracking bugs and enhancements. I think it would be more appropriate to post this on stackoverflow or use the POI users email list.

Original SO question:
https://stackoverflow.com/questions/65060554/how-to-create-pptx-file-for-link-video-in-slide-using-apache-poi

Old answer to this:

Please verify, if this still works ... (I haven't done so yet) ...

Hi Andreas,

Thanks for your quick reply.

The stackoverflow question which you mentioned, I am the one who requested that question 5 days before and still I have not got any answer.

And the Example Link which you mentioned the file name AddVideoToPptx.java.txt is the example for making embeded-video presentation which I have already created and it's working successfully.

My requirement is to create linked-video presentation. which file size is smaller and we have to take care of the existence of linked files. 

I also got one example 

http://svn.apache.org/repos/asf/poi/trunk/src/scratchpad/testcases/org/apache/poi/hslf/model/TestMovieShape.java

using this example, the created Pptx file giving error.


From last 20 days I am fighting for this and I have not get anything yet.
That's why I posted this request to you thinking that may be I can get something from here as you guys are creator of POI.

  I request apology to you that I requested this on bugzilla platform knowing this that it's not a bug, as you also aware the time-line for a project matters very much in software industry and request you that kindly help me out.


Thanks.

I does some changes in Embedded-Video presentation example. I commented the code section in which the byte-stream of file is adding in PackagePart class object. and in place of that I put bellow line

part.addExternalRelationship(video.getPath(), "http://schemas.microsoft.com/office/2007/relationships/media"); part.addExternalRelationship(video.getPath(), "http://schemas.openxmlformats.org/officeDocument/2006/relationships/video");

Also in Add Video method I during adding relationship to PackagePart of Slide I pass video Uri and TargetMode External by bellow line of code

prsEmbed1 = slide1.getPackagePart().addRelationship(video.toURI(), TargetMode.EXTERNAL, "http://schemas.microsoft.com/office/2007/relationships/media"); PackageRelationship prsExec1 = slide1.getPackagePart().addRelationship(video.toURI(), TargetMode.EXTERNAL, "http://schemas.openxmlformats.org/officeDocument/2006/relationships/video");

Doing this created a linked-video presentation but it gives error and needed to be repaired after that video played successfully.

I compared all the xml file of repaired one and non-repaired one and I find no any difference. So something I missed what I do not know? Can you help me in this?

Thanks

So if it crashes after the video was played successfully, try the following:

- the error mighty be still somewhere in your .pptx - check also the /[Content_type].xml, /ppt/presentation.xml and /ppt/slides/_rels/slide1.xml.rels

- keep replacing parts in your original / Powerpoint created version until it doesn't work anymore, e.g. synchronize the slide1.xml - my guess is, it might need a specific transition for the video

- I assume, it works correctly when you set it up in Powerpoint - if not, try a different .mp4
