Options for filters with several inputs (framesync)
Some filters with several inputs support a common set of options. These options can only be set by name, not with the short notation.
- 'eof_action'
-
The action to take when EOF is encountered on the secondary input; it accepts one of the following values:
- 'repeat'
-
Repeat the last frame (the default).
- 'endall'
-
End both streams.
- 'pass'
-
Pass the main input through.
- 'shortest'
-
If set to 1, force the output to terminate when the shortest input terminates. Default value is 0.
- 'repeatlast'
-
If set to 1, force the filter to extend the last frame of secondary streams until the end of the primary stream. A value of 0 disables this behavior. Default value is 1.
