vstools set_output with audio nodes inbetween breaks vspreview videonodes #111

Closed jsaowji closed 8 months ago

If there is a audio node in between video nodes, it breaks a video preview starting from last index.

This works

set_output([
    core.std.BlankClip(width=1920,height=1080),
    core.std.BlankClip(width=1920,height=1080),
    core.std.BlankAudio(),
])

This breaks last video

set_output([
    core.std.BlankClip(width=1920,height=1080),
    core.std.BlankAudio(),
    core.std.BlankClip(width=1920,height=1080),
])

This breaks last and 2nd last video

set_output([
    core.std.BlankClip(width=1920,height=1080),
    core.std.BlankAudio(),
    core.std.BlankAudio(),
    core.std.BlankClip(width=1920,height=1080),
    core.std.BlankClip(width=1920,height=1080),
])

Same behaviour with split set_output calls.
