I found 2 issues when I save a presentation with a video.
Test data https://drive.google.com/open?id=1esTc-kwJVv-fjsEEOfYGAavwgUzlxAf6
pp2007.pptx - created in PP 2007 (needs video.mp4 in the currrent directory)
pp2007_aspose.pptx - saved by Aspose.Sides for .NET 17.12.1
pp2016.pptx - created in PP 2016
pp2016_aspose.pptx - saved by Aspose.Sides for .NET 17.12.1
First issue - Aspose.Sides for .NET 17.12.1 do not copy volume of the video
Steps to reproduce:
- Save presentation (pp2007 or pp2016) by Aspose.Sides
- Open a saved presentation in PP 2016 and check video options.
Source presentation has ‘middle’ volumehttps://www.screencast.com/t/zOTRv4IUvQHI
But saved presentation has ‘low’ volumehttps://www.screencast.com/t/g2H1MQTni
c# code:
var presentation = new Presentation(fileName);
presentation.Save(Path.GetFileNameWithoutExtension(fileName) + “_aspose.pptx”, SaveFormat.Pptx);
Second issue - Video in copied presentation hangs in PP 2007
I can open copied presentation in PP 2016 and manually change volume. After it, If I click F5 it will run video without any issues.
Also I can open presentation pp2016 (created in PP 2016) in PP 2007. And when I click F5 it runs video.
But for both pp2007_aspose.pptx and pp2016_aspose.pptx - and can open it in PP 2016. But when I click F5 - video displayed extremely slow, it hangs.
This issue not dependent on PP 2007 version, because I can open source presentation from PP2016 (pp2016.pptx) without any issues.
