In fact, the current shuttle code seems to send a monitor pause request every few seconds. I am trying to fix it...

Should be fixed now in git

What is the desired behaviour of the shuttle in the mid position stop or the last running speed = 1 state?

Now:

1) Coming from backward => playback stop
2) Coming from forward => playback with speed 1

BTW: the jkl keys playback seems to be broken after this change!

I agree, this is the way it should work.

btw: in shotcut it is implemented in this way and I like it. Toggling the playback on K-Key press breaks a little bit the logic.

Same for shuttle.

The shuttle mid position (=> k key) doesn't stop transport

@j-b-m: I found that coming form neg shuttle position zero is fired (ShuttleXpress). Coming from pos zero is not fired. This is the reason why playback does not stop at mid-position.

Is it only a ShuttleXpress problem or a general one. Which Jog/Shuttle do you have?

I have a SpaceShuttle A/V, which is an old model (0000007:0000010 years old). With current git, it works correctly I think:

When moving the inner jog (the frame by frame jog), the playback stops.
When moving the outer ring (forward/backward), the playback also stops in all cases (whether the monitor was playing or not before turning the ring).

The only small issue I can see is that there is a small delay before pausing when you release the outer ring...

This was my suggestion that with your jotshuttle it works correct. I think that the jogshuttle behave different. For the ShuttleXpress I don't get the Zero Speed (Stop) event when coming from positive.

I think in future the code has to be rewritten like in kino considering the differences betweeen the jogshuttles. I very like to work with a jogshuttle thats why good support is important for me (in future).
