For examples and more explanations, see the module level docs.
FrameToYUV4MPEG() -> new FrameToYUV4MPEG component.
Parses uncompressed video frame data structures sent to its "inbox"
inbox and writes YUV4MPEG format binary data as strings to its "outbox"
outbox.

Outboxes
Methods defined here
Warning!
You should be using the inbox/outbox interface, not these methods
(except construction). This documentation is designed as a roadmap as to
their functionalilty for maintainers and new component developers.
canShutdown(self)
Returns true if the component should terminate when it has finished
processing any pending data.
checkShutdown(self)
Collects any new shutdown messages arriving at the "control" inbox,
and ensures self.shutdownMsg contains the highest priority one
encountered so far.
main(self)
Main loop
mustShutdown(self)
Returns true if the component should terminate immediately.
sendoutbox(self,
data)
Generator.
Sends data out of the "outbox" outbox. If the destination is full
(noSpaceInBox exception) then it waits until there is space. It keeps
retrying until it succeeds.
If the component is ordered to immediately terminate then "STOP" is
raised as an exception.
write_frame(self,
frame)
Generator.
Writes out YUV4MPEG format frame marker and data.
Generator.
Sends the YUV4MPEG format header to the "outbox" outbox, based on
attributes of the supplied frame data structure.
