I’ve created an Impress presentation which has to be exported as PowerPoint so a third-party can run it. The video component of the slides works well whether shown on a Linux (OpenSuSE) / Impress system or saved as a .ppt file and run on a Windows / PowerPoint system.
Two MP3 audio files provide background music for the whole presentation. The first one runs from slide-2 to slide 14, and the second from slide 15 to the end. This works fine on Linux / Impress if all three files are in the same path. (Using the slide-transition menu isn’t a problem - I know about the “Apply Transition To All Slides” catch!)
However it doesn’t work on the third-party’s Windows / PowerPoint system. It might if the location of the audio files were redefined in PowerPoint, but for practical reasons the whole presentation needs to be contained in one PowerPoinf file by embedding the audio.
I can embed the two audio files so they start at the appropiate two slides (#2 and #14) but they run only for the duration of those slides. How can I fix this? I understand PowerPoint has a “Presentation” window where these variables can be set.
