Add a property to show the active vf filters

[hooke007]

Expected behavior of the wanted feature

The ideal use case:

• run mpv with --hwdec=auto
• insert any active vf filter (mpv will enable auto-copy)
• remove all filters (mpv will switch to auto)

I tried to find a property to make a simple auto-profile/script to make it come true. But the reliable property seems not be exist.
vf is just a simple string. Even though invalid values were set, check vf will return True.

Is it possible to add a property to show the active vf filters (like vo-passes can allow checking the active shader)?

Alternative behavior of the wanted feature

Or other better methods?

vf will always return a table. When there are no filters, the table length is zero. There's no clever way to deal with this with using auto profiles currently AFAIK since vf will never be nil. So new functionality would have to be added to it.

profile-cond=vf[1]

Oh yeah that works.

profile-cond=vf[1]

Not perfect. Disabled filters will also be treated as 'active' ones.

Please reopen the issue. Because vf chain can be disabled internally (i.e. filters are disabled by labels or incompatible pixel formats). I wish a property to observe the 'active' filters. Which will be also useful in the script.

profile-cond=(function() for _, filter in pairs(vf) do if filter.enabled then return true end end end)()

Seems to be a workaround.
