As __tim must surely be relieved that i finally achieved this and will not
pester him so much about blocking probes ( atleast for a while.. ), I present
to you my masterpiece, my greatest achievement since modifying the ffmpeg tool
to be a function inside a library.

As the title says, this is a simple example that cuts a video stream ( i only
tested the general principles on h264 and raw yuv streams ) into multiple files
each 'numframes' key-frames.

I still don't know for sure why it works so I'll ask some questions here if
anyone cares to answer..

Does the tee save the h264 header to be sent to new dynamic elements?

It doesn't lose frames right now from the tests i conducted but should i send
FLUSH_START on the tee, block events on the tee's src-pad and only then link
the new sink?
