Changeset 637 for pjproject/trunk/pjsip/src/pjsua-lib/pjsua_media.c

Timestamp:

Message:

• Added iLBC codec (experimental) with the following features:
  • configurable default decoder mode (20 or 30),
  • encoder mode follows the mode specified in SDP fmtp from the remote's SDP,
  • silence detector uses pjmedia's,
  • PLC uses iLBC's PLC,
  • perceptual enhancement (penh) is configurable via codec param, as usual.

• iLBC mode is configurable in pjsua with --ilbc-mode option.

• Added packet lost simulation in pjmedia's UDP transport and in pjsua (with --rx-drop-pct and --tx-drop-pct options).

• Increase default buffer count in DirectSound? to 32 frames to make it more resilient to CPU disruption.

• Specify and parse fmtp mode in SDP for codecs that need it.
