See the results below. Nothing is flawed. Of course there can't be an
output in all cases, as you have pointed out correctly.
But for the remaining 95% of filters, the formats output is very useful.
(and correct)
Filter extractplanes
Extract planes as grayscale frames.
Inputs:
#0: default (video)
Outputs:
dynamic (depending on the options)
extractplanes AVOptions:
Filter alphaextract
Extract an alpha channel as a grayscale image component.
Inputs:
#0: default (video)
Outputs:
dynamic (depending on the options)
Filter waveform
Video waveform monitor.
slice threading supported
Inputs:
#0: default (video)
Outputs:
#0: default (video)
waveform AVOptions:
Filter vectorscope
Video vectorscope.
Inputs:
#0: default (video)
Outputs:
#0: default (video)
vectorscope AVOptions:
