Hi Jesus,
Thanks for your directions. From your email and my understanding
of the code of asterisk, I think that asterisk plays the audio and video
frames separately. Please correct me if I am wrong.
I was able to run the ffasterisk command, but I got exceptions and buffer
underflow/overflow with the audio/video files I tried.
It would be helpful if you can guide me to a working .avi file, from which
you extract the audio and video frames, and also comment on the correctness
of my steps outlined below. My approach should be as follows then:
ffasterisk -i in.avi -o in.wav --audio ;
Floating point exception
ffasterisk -i in.avi -o out.h263 --video
; buffer underflow, though file created, but didn't play in VLC media player
sox in.wav -r 8000 -c 1 -s -w out.wav resample -ql ;
was not able to find "ox"
In extensions.conf
exten => 600,n,Playback(out)
; and hope that it will play
Thanks for your help.
Regards
Sharan

You must have two files, one file .h263 with the video and other file
.gsm or .alaw with the audio.
Normally your converted files don?t work in Asterisk, you must
recodificate them.
ox in.wav -r 8000 -c 1 -s -w out.wav resample -ql ; To convert the audio
ffasterisk -i in.3gp -o out.h263 --video ; To convert the
video
Put the two files with the same name (in.h263 and in.wav). And this should
work.

Dear List Members,
I am trying to play videos in Asterisk. I understand that
Playback() and Background() functions can play videos in .h263 and .3gp
format. In my extensions.conf, I put a call like:
exten=> 600,n,Playback(testvideo) ;testvideo.h263 is a
file which which plays in VLC media player
I get an error saying "Unable to open testvideo format 0x4 (ulaw)".
I have made changes to my sip.conf,
videosupport = yes
allow=ulaw
allow=alaw
allow=h261
allow=h263
allow=h263p
allow=h264
I tried recording a video using Asterisk Record() function, and then tried
playing it using Playback(), but was unable to succeed.
Though my files get played in VLC media player, I am not sure whether they
are the right set for Asterisk.
I would request members on the list to kindly guide me to the correct
steps/examples/videos which play in Asterisk, so as to enable me to play
videos in Asterisk.
Thanks for your help,
Best Regards
Sharan

This kind of errors are normals, they are the logs of ffasterisk. If
you have the new file created itīs all correct

Normallly I create the audio in .wav with other applications, not with
ffasterisk, I donīt know if ffasterisk works fine with audio, Iīm
sorry.

Donīt worry if vlc doesnīt understand this file.

Finally if the video isnīt correct, you must hear only the audio. So,
you can test putting the video file with an audio file that normally
asterisk plays correctly (always putting the same name to video and
audio file).
