vf_scale: Detecting changes of incoming frame properties and dinamically evaluate width and height expressions
...
Currently scale filter accepts expressions in its width and height
parameters but evaluates them only once at init and replaces them with
their actual values. Later on, if any parameter of incoming frames
changes - ie those were used in the original size expressions - then
they new values will not have any affect for width and heigth values.
They remain the same. This patch makes possible that width and height
expressions be evaluated frame-by-frame basis if width/height/sar/format
properties of incoming frame would change. To retain the current
behaviour and not to break any earlier app, a new config parameter has
been introduced. Its name is "eval" and it has two distinct values:
"init" and "frame". The default value is "init".
This feature is very usefull in case of DVBT mpeg-ts streams where SAR
may change time-by-time from 4/3 to 16/9 and vica-versa and the size
remains the same and you want to create a variable sized output with 1/1
SAR.

vf_overlay: handles expression evaluation of frame size change in frame-by-frame evalutaion mode
...
vf_overlay video filter accepts expressions in its parameters. In
'frame-by-frame' evaluation mode it recalculates them regularly, but
incoming video frame size changes did not reflect in their values. So if
you used width or height of any source videos in expressions as
parameters, they stayed on their initial values. This patch corrects
this bug.
