Detailed Description

This is a special FrameFifo class for feeding frames into live555, i.e.

for sending them to the network.

Should not be instantiated by the user, but requested from LiveThread with LiveThread::getFifo()

There is a single LiveFifo instance per LiveThread

Member Function Documentation

writeCopy()

bool LiveFifo::writeCopy ( Frame *  f, bool  wait = false  )

virtual

Take a frame "ftmp" from the stack, copy contents of "f" into "ftmp" and insert "ftmp" into the beginning of the fifo (i.e. perform "copy-on-insert"). The size of "ftmp" is also checked and set to target_size, if necessary. If wait is set to true, will wait until there are frames available in the stack.

Reimplemented from FrameFifo.
