This func will return the first and last PTS from an MPEGTS clip by finding the first access unit, and then by moving backward from the end of the clip to find the start of the final PES packet.
Now that we want buffered senders (as required), the ringBuffer that was after the
lexer has been removed. Instead, we now have an ioext.multiWriterCloser to which the
lexer writes to. This then writes to the encoders, and then encoders write to each of
their own multiWriteClosers, which write to the appropriate senders. We now call
close on the first multiWriteCloser to close down the entired pipeline, as this close
call propogates through each level.
We have removed the outputClips routine as it's not required anymore to get data
from the revid ringBuffer, and have removed other things that were used by this, like
the IsRunning function.
We have also updated tests to work with these changes - they are passing.
Previously the encoder would not care if a write was given that exceeded the max PES packet size
because we were never using PES packets bigger than a frame of video. Now I have changed it so that
the encoder will check the write length and create a new PES packet if needed.
I have also restructured my test so that it can extract the data from PES packets that span accross multiple
MTS packets.
