Release Notes: A bug in the libavcodec based video frame conversion component was fixed. A bug in the PortAudio based audio input/output component was fixed. A component was added to allow reading raw YUV video frames from a file. Support was added for audio compression using the SILK codec. The build system was switched to CMake.
Release Notes: In this version, some important changes were made to the components responsible for video streaming. Apart from using an internal streaming format, H.263 frames can now be sent and received over RTP according to the standard. Audio input and output components for the Android platform are now available. Finally, some bugs were fixed in the component chain implementation.
Release Notes: This release added components for echo cancellation based on the routines in the Speex library. The U-law and A-law encoding components were improved. Support for libswscale was added. A component was added for decompressing JPEG encoded video frames using the TinyJPEG library.
Release Notes: This release adds a PortAudio sound capture/playback component. It improves the timing in the audio session class.
Release Notes: Some bugs were fixed. Several audio compression and encoding components were added: A-law encoding, LPC compression, and GSM compression. An OpenAL output component was added.
Release Notes: A bug in the Speex module of the RTP decoder was fixed. A simple WAV file writer was added (in case libsndfile isn't available).
Release Notes: Audio threads can now be started with high priority. A simple 3D component which only takes distances into account was added. Some bugfixes were made.
Release Notes: U-law encoding was added. An SDL output component was added. The transmission component was modified to allow registering specific handlers for specific RTP payload types. The links in the component chain can now be modified while the chain is active.
Release Notes: Sampling rate conversion can now be done without floating point calculations. JACK input and output components were added. Audio components were tested on Mac OS X (using the JACK sound system).
Release Notes: A bugfix was made in the audio session. An ESD output component and a libaudiofile input component were added. Several components can now use integer based samples instead of only floating point samples, for better performance on devices without floating point unit.
