>> Bodecs Bela (2018-03-11):
>>> I frequently use overlay video filter. Sometimes it is needed to 
>>> dinamically
>>> hide/show the ovelaid video. (e.g during live streaming).
>>> Currently the only possibility to hide the overlaid video is to 
>>> position it
>>> to off site area of the visible region.
>>> This patch creates a new, explicit property to controll 
>>> hiding/showing the
>>> overlaid video.
>>> 'show' property may be an expression, similary to x and y.
>>> The new 'show' property is controlable by command, also. So its 
>>> value can be
>>> adjusted dinamically during live sessions by zmq filters.
>>> To be compatible with existing stuff, its default value is "1".
>>>
>>> Please review this patch and consider putting this patch into the 
>>> official
>>> ffmpeg source tree.
>> Looks like a duplicate of the timeline editing feature, already
>> supported by overlay.
