Dear aman
You can just enable video support in sip.conf and start using point to point video calls in asterisk
You don't need any external plugin for this
Quality of video call depend on bandwidth you have.

that .I have downloaded AsteriskNow and installed in my server. I have
following questions , please response.
1. Is AsteriskNow good for Video calls.
2. Do I need any addon / plug in / Hardware for the server for video calls
.
3. How can we stream some static video contents through Asterisk.
4. Do we require any type of media server for contents or streaming video .

> 1. Is AsteriskNow good for Video calls.
If you only want to make video calls between SIP phones, then it should
be OK.
If you also do video streaming to SIP phones, or if you need video
telephony also to 3G UMTS video phones, then you need to patch Asterisk
and I think then it is better to use a plain Asterisk version.

For video calls: no, just enable video in sip.conf (search for video in
the sample config file)
For 3G UMTS video calls: yes. You need ISDN (or SS7) interface cards
For streaming (RTSP), recording and playback of video files: yes. You
need the applications from
https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/
> 3. How can we stream some static video contents through Asterisk.
For example you can store the video as mp4 file. Then use mp4play() to
playback the video to the caller. mp4play() is inlcuded in app_mp4.c
(https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/app_mp4/app_mp4.c)
> 4. Do we require any type of media server for contents or streaming video.
You have 2 options:
1. video is provided by Asterisk
SIP phone <--SIP+RTP--> Asterisk
^ (using mp4play())
|
video.mp4
2. video is provided by a streaming server (e.g. darwin) and Asterisk
(app_rtsp.c) bridges between the SIP call and the video stream.
SIP phone <--SIP+RTP--> Asterisk <---RTSP-------> Darwin
(using rtsp()) ^
|
video.mp4
> 5. What are the basic steps for integration Video with asterisk server.
Hint: only try the enxt step if the previous works
1. Install a "vanilla" (plain) Asterisk
2. Start with SIP-to-SIP video calls. By 2 webcams and use XLite to make
video calls. (enable video in sip.conf)
3. Try also with the Echo() application. Then the caller should see itself.
4. Add app_mp4.c to Asterisk and reinstall Asterisk
5. Use mp4save() to record a video call from a SIP phone. Use mpeg4ip
tools to analyze the recorded video (audio, video and hint tracks).
6. Use mp4play() to playback the recorded video to the SIP phone
7. use ffmpeg and mpeg4ip tools to create a video with hint tracks. Then
playback this video to the caller using mp4play.

Hi Aman,
We had tests to pass video h324m calls with sip audio calls (SIP/RTP
alaw) and it works fine too.
You can use a VoIP provider (but without echo cancellation, and without
any transcoding) or a front end Asterisk to forward video calls (as a
switch/gateway).
(We done some modifications in our VXI to convert an Asterisk in a
transparent call forwarder for the video : Asterisk normaly convert the
audio in PCM...).
My company uses the Sergio's tools through our Asterisk VoiceXML browser
and all works fine.
If you use SIP Video Phone, you will probably need to add the transcoder
because most of the soft phones don't be able to respect the H324m video
profile (bandwidth limitation and strict h263 video codec).
Regards,
Borja from i6net
