MacGui: Live Preview Fixes

- Fixes and Issue where using chapter markers on ffmpeg input sources caused a crash and or no encode and a gray screen.
- Fixes an issue where not manually selecting a still preview caused the live preview encode to crash.
- Many thanks to refulgentis for troubleshooting this for me. :)
