[Live-devel] Buffer size in MPEG2TransportStreamFromESSource

Yes.  However, I don’t want to do this by adding a ‘buffer size’ parameter to the API, because sometime in the (admittedly likely distant) future, I’d like to overhaul the way that buffer management is done in this library by eliminating these fixed-size buffers altogether.

Instead, in the next release of the software, I’ll change “MAX_INPUT_ES_FRAME_SIZE” from a compile-time constant to a run-time variable that can be changed before the “MPEG2TransportStreamFromESSource” object is created (similar to  what we currently do with "OutPacketBuffer::maxSize”).
