I need to stream live amr data using live-555.
For this i have written a buffer(subclass of FramedSource).
This should be a subclass of "AMRAudioSource", not just "FramedSource".
I am converting the live raw audio to amr(sample: 8000Hz, bit-rate:
12200) using ffmpeg and writing to the buffer.
Also, your class (a subclass of "AMRAudioSource") should properly set
the fields
Boolean fIsWideband;
unsigned fNumChannels;
u_int8_t fLastFrameHeader;
which you inherit from "AMRAudioSource".
I have modified AMRAudioFileServerMediaSubsession to take my buffer
as source instead of AMRAudioFileSource.
No, you shouldn't modify the existing code; it works just fine for
its purpose. Instead, you should write a *new* class - a subclass of
"ServerMediaSubsession" - that does what you want. (It will likely
copy much of the code from the existing
"AMRAudioFileServerMediaSubsession" class, which you should not
change.
I also modified AMRAudioRTPSink to take my buffer as source instead
of AMRAudioSource.
No, you definitely should not modify "AMRAudioRTPSink"; there is
nothing wrong with it. Just use this class as is. (Because your new
input class is a subclass of "AMRAudioSource", the existing code will
continue to work.
