We are writing our own depacketizer to convert a G.711_ALAW 8000Hz Mono to a PCM 8000Hz 16bit Mono during re-streaming. We are using a similar method to what you see in http://www.wowza.com/forums/showthre...ing-RTP-stream. The problem we are having is that the we could not find the frameType values for IVHost.CODEC_AUDIO_PCM_LE that correspond to PCM 8000Hz 16bit Mono. We tried the values up to 20 and sampling rates jump from 5512 to 11025. Is 8000 not a supported sampling rate for CODEC_AUDIO_PCM_LE? Do you have documentation for possible frameType values for corresponding codec types?
