All Known Implementing Classes:
g711a, g711u, g722, g729a, gsm, opus, speex
public interface RTPAudioCoder
RTPAudioCoder Base interface for all audio codec encoders/decoders. Encoders build RTP packets from raw audio samples. Decoders build raw audio samples from RTP packets.

    Sets RTP payload ID.

  • Method Details

    • setid

      void setid(int id)
      Sets RTP payload ID. This value is exchanged in SDP packets. For most audio codecs this value is fixed and ignored.

    • encode

      byte[] encode(short[] src16)
      Encodes audio samples into RTP packet.

    • decode

      short[] decode(byte[] src8, int off, int length)
      Decodes RTP packet into audio samples.

    • getSampleRate

      int getSampleRate()
      Returns sample rate.

    • getPacketSize

      int getPacketSize()
      Returns encoded packet size (excluding RTP header) -1 = variable sized

    • close

      void close()
      Free any resources.
