Exporting video can take a long time. Pupil Player writes the result incrementally to disk. Specifically, it writes the result directly to the final export location. While the export is ongoing, the video file is invalid but still available to the user. This can lead to users opening the video before it has finished exporting and then encountering playback issues.
This PR changes the video exports to include a
.writingfile name suffix during the export. This prevents other applications from recognizing the partially exported video file as complete. Once the export is done, the suffix is removed and other applications are able to recognize the file type as video.
