Filter overlay
Overlay a video source on top of the input.
slice threading supported
Inputs:
#0: main (video)
#1: overlay (video)
Outputs:
#0: default (video)
overlay AVOptions:
x <string> ..FV……. set the x expression (default “0”)
y <string> ..FV……. set the y expression (default “0”)
eof_action <int> ..FV……. Action to take when encountering EOF from secondary input (from 0 to 2) (default repeat)
repeat 0 ..FV……. Repeat the previous frame.
endall 1 ..FV……. End both streams.
pass 2 ..FV……. Pass through the main input.
eval <int> ..FV……. specify when to evaluate expressions (from 0 to 1) (default frame)
init 0 ..FV……. eval expressions once during initialization
frame 1 ..FV……. eval expressions per-frame
shortest <boolean> ..FV……. force termination when the shortest input terminates (default false)
format <int> ..FV……. set output format (from 0 to 7) (default yuv420)
yuv420 0 ..FV…….
yuv420p10 1 ..FV…….
yuv422 2 ..FV…….
yuv422p10 3 ..FV…….

auto 7 ..FV…….
repeatlast <boolean> ..FV……. repeat overlay of the last overlay frame (default true)
alpha <int> ..FV……. alpha format (from 0 to 1) (default straight)
straight 0 ..FV…….
premultiplied 1 ..FV…….
framesync AVOptions:
eof_action <int> ..FV……. Action to take when encountering EOF from secondary input (from 0 to 2) (default repeat)
repeat 0 ..FV……. Repeat the previous frame.
endall 1 ..FV……. End both streams.
pass 2 ..FV……. Pass through the main input.
shortest <boolean> ..FV……. force termination when the shortest input terminates (default false)
repeatlast <boolean> ..FV……. extend last frame of secondary streams beyond EOF (default true)
This filter has support for timeline through the ‘enable’ option.
