Bela Bodecs	868a2ed568	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.

Bela Bodecs	cc83177db4	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.
