[ANURAG SINGH IIT BHU]

How to write a ffmpeg-libavfilter filter which outputs a "Hello World
minute:sec" subtitle each second.The filter should produce packets/frames
of subtitles in a AVMEDIA_TYPE_SUBTITLE stream output from the avfilter.The
output from the filter should be passed through the filter chain back into
the application (ffmpeg*.c).
