I have 2 media files:
- Video+(2x)audio (Movie).
- Audio (Commentary).
Commentary audio track starts with an offset before the movie starts.*
I need to be able to(simultaneously):
- See the video track of the first file.
- Hear one of the the audio tracks of the first file.
- Hear the audio tracks of the second file.
- Play/Pause, FFW/RWD (or seek on the progress bar) all of the video/audio tracks simultaneously.
- Set volume balance between the two playing audio tracks.
- *Set an offset for the auxiliary audio track (commentary).
I need not to mux/resample or in any way edit the source media files as this would disable dynamic volume balance control (and possibly deteriorate quality).
How can I achieve this?
Already tried to no avail:
- Multiple instances of players with global keys. VLC and MPC-HC tested.
Resulted in one of the instances possessively claiming the shortcut. - Bino.
Just doesn't seem to work at all.
