Two fixes were involved, firstly, access unit delimeters were used to denote access units and the Write timeout on rtmpSender's ringBuffer was
increased to stop the 'unable to dump old write' errors. Also made some small changes elsewhere that should fix future issues, particular with
MTS output.
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.
