Message:

Fix #1547:

• Added PJMEDIA_MAX_MRU to specify maximum packet size in receiving direction.
• Added max_pkt_size into pj_turn_sock_cfg, default is PJ_TURN_MAX_PKT_LEN.
• Fixed hardcoded MTU settings in media transport SRTP.
• Added MIN_CHUNKS_PER_FRM constant in video stream.

Notes:

• PJMEDIA_MAX_MTU & PJMEDIA_MAX_MRU to specify max packet size for TX and RX dir.
• For ICE media transport, TURN session limits outgoing packet size to PJ_TURN_MAX_PKT_LEN (the size of internal buffer for inserting TURN overheads).

• pjproject/trunk/pjmedia/src/pjmedia/transport_udp.c (modified) (3 diffs)
