Hi Ross, I have problems streaming live PCM audio. Audio comes either directly from microphone (16-bit LE) Sampling frequency is 8k, mono(1 channel). I receive a buffer in the thread and use event trigger to signal my live555 thread.
I've created class based on DeviceSource that inherit from AudioInputDevice and delivers the Frame on trigger. I am using uLawFromPCMAudioSource to convert to 8-bit u-law audio I am getting following error if I am giving audio format as WA_PCM: FramedSource ::getNextFrame():attempting to read more than once at the same time. One thing I observed here is FramedSource::getNextFrame is getting called twice at a time( uLawFromPCMAudioSource is calling it again) If I change audio format to WA_PCMU, I am able to stream without any error ( As FramedSource::getNextFrame is getting called once at a time), and VLC also able to play with some noise. Where I am going wrong ? Thanks in advance Regards, Krishna
