FreeSWITCH Week in Review (Master Branch) October 24th-October 31st

FreeSWITCH got some neat improvements this week with work going into improving the handling of vw and vh core file parameters in mod_av to avoid video cropping and crashing, the addition of a new configuration setting in mod_opus to show the decoder stats at the end of the call, and exposing SRTP and SRTCP crypto keys as channel variables to help with debugging.

Join us Wednesdays at 12:00 CT for some more FreeSWITCH fun! And head over to freeswitch.com to learn more about FreeSWITCH support.

New features that were added:

• FS-8281 [core] Expose SRTP and SRTCP crypto keys as channel variables to aid with debugging
• FS-8313 [mod_opus] Introduced new configuration setting ‘decoder-stats’ to show decoder stats at end of call (how many times it did PLC or FEC)
• FS-8380 [mod_av] Improve the handling of vw and vh core file parameters to avoid video cropping and crashing

Improvements in build system, cross platform support, and packaging:

• FS-8389 [build] Fixed msvc 2015 build warnings
• FS-8398 [Ubuntu] Added event_handlers/mod_amqp to avoided modules for Ubuntu 14.04 Trusty

The following bugs were squashed:

• FS-8222 [verto_communicator] Updated getScreenId.js in order to detect plugin issues and attached an ‘ended’ event to screenshare stream in order to detect ‘stop sharing’ click
• FS-8392 [mod_av] Fixed rtpmap to allow both H263 and H263+ codecs to be offered
• FS-8373 [mod_av] Fix for bad recording quality when using fast encoding
• FS-8397 [core] Fixed a race condition incrementing the event-sequence number
• FS-8154 [core] Fixed a segmentation fault occurring while eavesdropping on video call
• FS-8391 [core] Fixed a SDP parsing error for rtcp-fb
• FS-8319 [mod_opus] Fixed and cleaned up switch_opus_has_fec() and switch_opus_info() to avoid FALSE positives for packets with FEC at high frame sizes.
• FS-8344 [mod_opus] Toggle FEC ON only on the last frame which is to be packed

The FreeSWITCH 1.4 branch had a few bug fixes added this week.

The following bugs were squashed:

• FS-8338 [core] Fixed an issue when setting the ringback variable with an outbound call via the bridge app, if the inbound leg is stereo the ringback tone is still rendered as mono causing the resulting ringback to be higher pitched and incorrect.
• FS-8378 [mod_esf] [core] Fixed a crash when using esf_page over loopback when transcoding and added tests for esf over loopback. Also refactor a bit to clarify code and get better debug in gdb
• FS-8370 [mod_rayo] Fixed another place in where a message was freed after being queued for delivery. This resulted in a freed object being serialized, crashing FS
