FFmpeg (LGLP) is used by Turbo Play:
- To export video instead of using Media Foundation. This means better compression at the expense of (way) slower speed, but it may be good if you don't have a good GFX card.
- To import subtitles from MKV.
- To create MKV files from MP4+Subtitles.
- To convert videos using the Video converter workspace.
- To split videos using the Movie Cut workspace.
