Description Matt K 2024-01-19 15:40:00 UTC
Description:
This report is about implementing the Microsoft Media Foundation APIs[1] in LO so that, for example, Impress can play .mp4 files within its presentations on Windows (something not possible currently).  Some tools and sample code are also provided by Microsoft[2].  The work involves replacing existing DirectShow APIs, as recommended by Microsoft.

Steps to Reproduce:
On Windows, try to insert a video file (.mp4) into a Impress presentation.

Actual Results:
Get error message

Expected Results:
Should be able to play


Reproducible: Always


User Profile Reset: No

Additional Info:
See https://opengrok.libreoffice.org/xref/core/avmedia/source/win/player.cxx?r=c0e51660#94 for the DirectShow APIs currently used by Impress (which don't work).

This seems highly desirable, so let's set to NEW.
Comment 2 Matt K 2024-01-20 16:15:19 UTC
Was able to get example program from https://learn.microsoft.com/en-us/windows/win32/medfound/media-session-playback-example to work with arbitrary .mp4 files, so will start working on integrating into Impress.

Duplicate of bug 62408, please see that for code pointers and analysis.

Thanks, I read it over and it still seems like this bug is valid.  By the way, I got arbitrary .mp4 files to play in Impress so far using the Media toolbar with Media Foundation, but still not yet playing in presentation mode.
