When I run live555MediaServer.exe, program send "throw" in the middle of making
SDP lines.
As you can see below backtrace it happened in void
StreamParser::ensureValidBytes1
The problem is StreamParser::afterGettingBytes never called back in synchronous
mode.
Because of ByteStreamFileSource::doReadFromFile just schedule it rather than
call FramedSource::afterGetting directly
I don't know how live555 scheduler worked, exactly but this logic seem to
wired..
Anyone show me the way how to handle this?
