[asterisk-dev] Setting of Channel Native Format

[Sharan Saxena]

Dear List Members,
                  I am trying to play .h263 videos in Asterisk-1.6-beta
version. I have taken a .avi file, and using the FFasterisk library, extract
an audio file test.wav and a video file test.h263 from it. The video doesn't
play, when I call it my dial-plan through Playback(test).

In the ast_openvstream() function in file.c, I see the following condition:
	
struct ast_filestream *ast_openvstream(..)      /* Process Video Stream
{
    for() 
    {   //Iterate over the list of available formats
        if (!(chan->nativeformats & format))
            continue;
//This always happens in my case. Print chan->nativeformats = 4

        //Otherwise locate file, open the video stream, and play it
     }

     //If, nothing worked, then 
      return NULL;
}

I think there is a mismatch between the available formats and the set
channel native formats, for my case. I would request your kind help to
enable me identify the place where we set the chan->nativeformats. I also
find that the chan->vstream in NULL.

Thanks very much for your help in advance.

Best Regards
Sharan
