1 Asterisk and Video telephony
2 ----------------------------
4 Asterisk supports video telephony in the core infrastructure. Internally, it's one audio stream
5 and one video stream in the same call. Some channel drivers and applications has video support,
10 Asterisk supports the following video codecs and file formats. There's no video
11 transcoding so you have to make sure that both ends support the same video format.
17 H.261 - Passthrough only
19 Note that the file produced by Asterisk video format drivers is in no generic
20 video format. Gstreamer has support for producing these files and converting from
21 various video files to Asterisk video+audio files.
23 Note that H.264 is not enabled by default. You need to add that in the channel
28 SIP The SIP channel driver (chan_sip.so) has support for video
29 IAX2 Supports video calls (over trunks too)
30 Local Forwards video calls as a proxy channel
31 Agent Forwards video calls as a proxy channel
35 This is not yet a complete list. These dialplan applications are known to handle video:
37 voicemail Video voicemail storage (does not attach video to e-mail)
38 record Records audio and video files (give audio format as argument)
39 playback Plays a video while being instructed to play audio
40 echo Echos audio and video back to the user
42 There is a development group working on enhancing video support for Asterisk.
