Looking then at the code and attaching with the debugger.
the ast_openstream_full() function has this condition:</pre>

</pre>
<pre style="white-space:pre-wrap;color:rgb(0,0,0)">So fileexists_core() returns 1 but the next call to ast_format_cap_has_type() fails. because its looking for AST_MEDIA_TYPE_AUDIO and the file is a video file. Nowhere is the an AST_MEDIA_TYPE_VIDEO.</pre>

Hi Jerry,<br>
<br>
I just had a look through the code, and from what I can tell, what
you're trying to do is not supposed to work, exactly. It appears
that what Asterisk expects is to be given a filename, such as
"myplayback". Asterisk will first search for an audio version of the
file (like myplayback.gsm or myplayback.opus), and open that as an
audio stream. If that succeeds, it then will also see if there is an
accompanying video stream (such as myplayback.h264). If it then
finds that video, then the result will be that Asterisk will play
the audio from the audio file and the video from the video file.<br>
<br>
What this means is that Asterisk does not properly handle:<br>
* Files that have audio and video streams contained within<br>
* Video files without accompanying audio<br>
<br>
This is one of those times where Asterisk's handling of video is not
user-friendly and in general ass-backwards and terrible. If you have
a tool that can extract the audio to its own file, then you would be
able to run your scenario, presumably.<br>
<br>
It would be a welcome addition for Asterisk to be able to open a
single file containing video and accompanying audio and be able to
play those back.<br>
