== New Features ==
=== Video ===
Assorted features:
1. Supported video devices:
- renderer:
- Simple Direct Media Layer (SDL) (Win32, Mac OS X, Linux, etc.)
- iOS UIView
- capture:
- !QuickTime (MacOS X)
- Video4Linux4 (Linux)
- !DirectShow (Win32)
- iOS AVFoundation (iOS 4 or later)
- ffmpeg capture (unfinished)
- Color bar (all platforms)
1. Supported codecs:
- H.263 (with ffmpeg)
1. video device port to provide timing for video devices (analogous to sound device port)
1. media format conversion framework (converter.h) supporting multiple backend APIs:
- ffmpeg's libswscale backend API implementation
1. video codec framework (vid_codec.h) supporting multiple backend APIs:
- ffmpeg's libavcodec backend API implementation
1. AVI file splitter/reader component (aviplayer.h)
=== On Demand Media Transport ===
Media transports are now created on demand. Rationale is given in #539. Media transport setting is now part of account setting (instead of global setting). Idle timer is used to keep media transports alive and close them after idling for some time. The idle period and number of transports that are allowed to be idling are settable.
For incoming calls, the "on_incoming_call()" callback is now called before media transport is created, to allow application to reject the call cheaply. The media transport will be created as soon as the callback returns, as long as the call is not disconnected. The media transport creation may take a while to complete (for example, waiting for candidates gathering for ICE media transports). If application sends 183/Progress or 200/OK to the call while the media transport creation is in progress, the response will be queued internally.
For outgoing calls, the INVITE request will be delayed until media transport is ready.
=== Other Components ===
New components:
1. Event framework
1. pj_run_app()

== Changes ==
=== PJSUA API (pjsua.h) ===
Design change:
- support for multiple medias. pjsua_call struct refactored.
Removed API:
- PJ_DECL(pjmedia_session*) pjsua_call_get_media_session(pjsua_call_id call_id);
- PJ_DECL(pjmedia_transport*) pjsua_call_get_media_transport(pjsua_call_id cid);
API change:
- "session" parameter in {{{on_stream_created()}}} and {{{on_stream_destroyed()}}} callbacks has been replaced by "stream"
