[Asterisk-video] name of file for video playback

[Jerry Geis]

Asterisk 11.25.1 playing with...
Playback supports these formats.

Supported video codecs

   - H.261 <http://www.voip-info.org/wiki/view/H.261>
   - H.263 <http://www.voip-info.org/wiki/view/H.263>
   - H.263p <http://www.voip-info.org/wiki/view/H.263p> (Asterisk 1.4)
   - H.264 (Asterisk 1.4)

I have a call file I'm using Application: Playback
Data: /tmp/video

I am using a bria 4 softphone with  h264 enabled.
The message I see on the console is:

File /tmp/video does not exist in any format
Unable to open /tmp/video (format ulaw|h263|h264)

In fact I have the file /tmp/video.h264 and is readable by owner group and
world.

What am I not doing correctly to get an h264 video file to play?
Thanks,

Jerry
