This ticket will add support to FFmpeg 2.8 with these general modifications:

• Change FFmpeg const using 'AV' previx. e.g: PIX_FMT_NONE -> AV_PIX_FMT_NONE
• Change deprecated method avcodec_get_frame_defaults() -> av_frame_unref()

Application may keep using older FFmpeg version, i.e: the versions that are already supported before the changes in this ticket, by defining macro PJMEDIA_USE_OLD_FFMPEG in the build, e.g: adding this line in config_site.h:

#define PJMEDIA_USE_OLD_FFMPEG

Note: configure script (of GNU autoconf build system) will automatically add this macro when it detects that older FFmpeg version is being used.

Support Windows 10 / Universal Windows Platform and continue the work for Windows Phone 8 support (#1704).

Build guide: Building for UWP & WP8

The crash can be seen when using Asterisk 11+ in a very small number of calls (1 in 10,000) and can also be seen as a 100% CPU utilisation in some cases.

It seems to have started due to an optimisation in Chrome 47+ which triggers this timing-related problem. In the STUN engine, a retransmit cache is maintained in

sess->cached_response_list

When this linked-list of data is modified, the relevant lock

sess->grp_lock

is held in all places except one.

A cache expiry timer is set on the above list, which fires

on_cache_timeout()

to clean the cache. This function does not get the group lock before trying to empty the list.

Thanks to Steve Davies for the report and patch
