* avfilter/zoompan: add in_time variableexwm2020-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the zoompan filter exposes a 'time' variable (missing from docs) for use in the 'zoom', 'x', and 'y' expressions. This variable is perhaps better named 'out_time' as it represents the timestamp in seconds of each output frame produced by zoompan. This patch adds aliases 'out_time' and 'ot' for 'time'. This patch also adds an 'in_time' (alias 'it') variable that provides access to the timestamp in seconds of each input frame to the zoompan filter. This helps to design zoompan filters that depend on the input video timestamps. For example, it makes it easy to zoom in instantly for only some portion of a video. Both the 'out_time' and 'in_time' variables have been added in the documentation for zoompan. Example usage of 'in_time' in the zoompan filter to zoom in 2x for the first second of the input video and 1x for the rest: zoompan=z='if(between(in_time,0,1),2,1):d=1' V2: Fix zoompan filter documentation stating that the time variable would be NAN if the input timestamp is unknown. V3: Add 'it' alias for 'in_time. Add 'out_time' and 'ot' aliases for 'time'. Minor corrections to zoompan docs. Signed-off-by: exwm <thighsman@protonmail.com>

* lavfi: split frame_count between input and output.Nicolas George2016-11-13
| | | | | | | | | | | | AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.
