Commits work in progress on utilizing Android's native hardware (and software) decoding (and encoding) via MediaCodec.

Fixs a NullPointerException in the H.264 encoder which could prevent the building of a flow graph (e.g. Android). Does not attempt to enable RTCP feedback for H.264 video on Android because that does not have a way of working there.

Does not allow the FMJ encoder and decoder classes of Opus to register with FMJ/the application unless the jnopus JNI library is loaded and appears functional. Otherwise, the Opus codec will be considered supported and advertised as such while the JNI library may not be available at all (e.g. Android).

Updates FMJ to r15: Removes a NullPointerException which is said to have been placed for the purposes of JMF compatibility but is inappropriate anyway.

Uses device UID or name (instead of index) for PortAudio CaptureDeviceInfo locator. This fixes the problem of starting/stopping the wrong device after an update of the device list (i.e. a device has been dis/connected.).

Updates audio device selection: selected device is now put on top of the device list, instead of on top of the active device list.

Fixes a problem with the VP8 Packetizer sometimes not sending the last chunk of a packet correctly. Changes the VP8 encoder and decoder used to the ones based on libvpx. Updates libjitsi.jar

Adds a JNI interface to libvpx via the org.jitsi.impl.neomedia.codec.video.VPX class. Adds a VP8 encoder and decoder based on that interface.

Adds a 'libvpx' target used to build the (soon to be added) jnvpx library. Reverts the instruction for building the jnffmpeg library, since libvpx won't have to be compiled into it anymore.

Commits work on progress. Prepares to keep video frame memory entirely in the native, non-Java heap.

Re-enables Periodic Intra Refresh in the H.264 encoder which was (relatively) recently disabled during updates to the FFmpeg and x264 libraries. Contributed by Benoît Laniel.

Refactors AVFrame, ByteBuffer and ByteBufferPool. Prepare to invoke FFmpeg's avcodec_free_frame(AVFrame **) which is the new way to free AVFrames.

Fixes an issue of overlapping videos which could cause the local video in a call to be displayed bellow the remote video. Works on remedying issues with telephony conferences utilizing the Jitsi VideoBridge server-side technology.

Adds support to encode and decode VP8. Note that a vp8 encoder and decoder need to be build into the jnffmpeg library in order for this to work, and prebuild binaries aren't ready yet.

Creates a dedicated thread for changing on-going call volume. Uses the system volume to update the volume slider when the slider becomes visible.

Ports Portaudio WMME device timeout system to MacOsX CoreAudio in order to avoid deadlock when a device is unplugged.
