I spend many hours to find out a close caption framework for restrict to play a swear word from the video. What I did so far:
If I am not wrong we can do with two approaches
Embedded captions – because these formats are added to video files at the point of transcoding.
a) Arduino can control hardware command such a mute and others.
We can give supported input file (e.g. TTML or WebVTT or DFXP ) in different player .But with right Flash/HTML player and single file caption.
a) We can give TTML/DFXP and WebTT with close caption detail in third party player. i.e. Brightcove, OOYALA
I am looking for third approach without use any hardware.
