At end it will output number of frames detected as having variable delta
pts, and ones with constant delta pts. If there was frames with variable
delta, than it will also show min, max and average delta encountered.
Yes I understand, but in which unit the delta is measured, is it nano seconds
or what?
In your linked document this is not mentioned.
You can increase output framerate for constant frame rate video until
errors about dropped frames disappear. Or save it to container that support
variable frame rate.
Does this mean to use "-fps_mode passthrough"?
As a first try, I have used "-fps_mode drop".
This resulted in a video with 1110244 fps instead 25.
Weird !
Could also inspect those frames and see if they have any real info and are
not dupes of some other frames, either manually or using some filters.
Good idea !
