What’s New

Version 5.0 of the QTSS programming interface provides the following new features:

• These new internal server preferences have been added: disable_thinning, player_requires_rtp_header_info, and player_requires_bandwidth_adjustment.

• These new preferences have been added to the QTSSFileModule module for compatibility with 3rd Generation Partnership Project (3GPP) players: compatibility_adjust_sdp_media_bandwidth_percent and enable_player_compatibility.

• RTP play information is now enabled by default in the QTSSReflectorModule module. Use the new preference, disable_rtp_play_info to disable RTP Play information. Another new QTSSReflectorModule preference is reflector_rtp_info_offset_msec. For compatibility with 3GPP players, these preferences have also been added to the QTSSReflectorModule module: enable_play_response_range_header, enable_player_compatibility, and force_rtp_info_sequence_and_time.

• This new preference has been added to the QTSSFlowControlModule module: flow_control_udp_thinning_module_enabled.

The following changes have been made to existing preferences:

• Default size of the QTSSFileModule preference shared_buffer_unit_k_size has been increased from 32 to 64.

• Default size of the QTSSFileModule preference private_buffer_unit_k_size has been increased from 32 to 64.

The enable_rtp_play_info preference has been removed from the QTSSReflectorModule module.

The -D command line option has been added to the StreamingServer. When specified, the -D option outputs performance status information.

The file streamingloadtool.conf, installed in /Library/QuickTimeStreaming/Config, has new file tags:

• player text, where text is the name of the RTSP player. The information is sent to the server as the UserAgent header.

• sendoptions setting, where setting is yes or no. If yes, a Send Options request is made before the DESCRIBE statement.

• requestrandomdata setting, where setting is yes or no. Set setting to yes to ask for random data from the server.

• randomdatasize setting, where setting is a number from 0 to 262144 that specifies the number of random bytes the server should send.
