FreeSWITCH Audio and video

FreeSWITCH supports audio and video recording functions, recording function is mainly through Mod_sndfile, mod_shout and other modules to achieve, video module is through the MOD_MP4V2 and Mod_av modules.

Mod_sndfile Recording wav

Mod_shout Recording mp3

Mod_mp4v2 recording MP4 file

Mod_av is a new module available in the 1.6.x release

I also put the Mod_av in the 1.5.x version, the use of this module to play video files, connect the camera and other functions. Video function using MOD_MP4V2 module implementation, have to say this module or toss a short time, the final effect can also be reached dozens of VGA simultaneously video, high concurrent audio and video comparison synchronization, CPU is not high, the bottleneck is mainly reflected in the bandwidth.
