Playing 2 Videos Synchronously no longer works starting v3.0.0
This feature works wonderfully up to version 2.2.8 (the latest version I can find). However, starting version 3.0.0 it only plays the main video added. I tested it using two mp4 files.
This is a very useful feature when playing 2 related video files, synchronized, with the ability to control both videos using one playback control (e.g. skip to a time for both videos while maintaining synchronicity). e.g. one video file of a lecture showing the presenter, and one video file of the same lecture showing the presentation
This feature may be used by... Media>Open Multiple Files. Inside the multiple file windows select add to add the first file. After this click on the, "Show more options," checkbox followed by the, "Play another media synchronously," checkbox at the bottom of the window. Select browse next to, "Extra media," to add the second file. Hit play and the two media files will play simultaneously, in sync, with a single control window.
