Hi all,
If Live555 can not vary transfer bitrate. How does Live555 deal with low
bandwidth? I mean, at the moment that Live555 stream data and there is a
low bandwidth it suppose to loss frames/data. Does Live555 implement a
mechanism to avoid this kind of problems?
Suppose I have a client that feedback, I can know if I have a problem
with my bandwidth and probably I can modify a Live555 variable to reduce
loss frames/data.
Regards and thanks in advance

No.

Yes, you (the server implementor) can stream from a
"ByteStreamMemoryBufferSource", instead of from a
"ByteStreamFileSource". To use this, you would write a new subclass of
"ServerMediaSubsession", and reimplement the virtual function
"createNewStreamSource()".
Note, though, that to use "ByteStreamMemoryBufferSource", the memory
buffer must be static - i.e., fixed-size, and filled in with data ahead
of time. If, instead, you are using the memory as a FIFO, then you must
write your own source class (perhaps using our "DeviceSource" code as a
model) to encapsulate it.
