I am using Vmix to play a swf which plays a live stream.

Is there any way to mute or adjust the audio for swf files? Although the swf input shows in the audio mixer the slider seems to have no effect.

Thanks

Hi Nav,

Unfortunately the Adobe Flash Player does not provide any volume controls so vMix can't control the volume or mute of any SWF files.
I would suggest using the RTMP url directly if possible (as this has audio controls).

Hi Martin,

Thanks for the info. I am experiencing some difficulty with rtmp streams. Our server path is something like:

rtmp://server.com/folderA/folderB/abc and the stream name is "stream".

If I enter rtmp://server.com/folderA/folderB/abc/stream in the AddInput->RTMP section I get an error.

The stream plays fine through a flash player - I am wondering if Vmix is able to handle rtmp paths with nested directories.

Thanks

vMix uses the Adobe built Strobe Media Playback swf internally for handling RTMP streams.

http://www.osmf.org/strobe_mediaplayback.html

You may need to refer to the documentation to work out how to format the URL.
You can also download the strobe media playback source and samples and try getting it working there first.

Regards,

Hi Martin,

I have worked out the required parameters for StrobeMediaPlayback following your suggestion:

streamType=live
urlIncludesFMSApplicationInstance=true

and additionally the rtmp src needs to be reformatted as:

rtmp://server.com/folderA/folderB/abc:stream

How can the parameters be passed to the StrobeMediaPlayback.swf in the "flash" folder?

Perhaps a parameter entry box in AddInput->Flash/RTMP would do the trick.

Thanks

Have you tried including the parameters with the URL?:

rtmp://server.com/folderA/folderB/abc:stream?streamType=live&urlIncludesFMSApplicationInstance=true

I think whatever you type in the existing entry box in AddInput->Flash/RTMP gets passed as the "src" flashvars attribute to the StrobeMediaPlayback object.

Hi Jon,

Yes I have tried this - it doesn't work.

If you specify a .swf file instead of rtmp path then adding url parameters as you have described targets the swf file, not the underlying Strobe swf.

It appears that Vmix sends whatever is typed in as a "src" flashvars parameter, however what I am looking to do is send a different attribute altogether (not src). Martin could confirm if my understanding is correct.
