In the Trial and 4K versions, there is another choice for "External 2" which sets the input source for the 2nd external output.

An update to vMix 14 Preview has been uploaded (14.0.0.71)

http://www.vmix.com.au/download/vmix14preview.exe

I've been away at IBC, so there are only a couple of small but important fixes/updates in this version.
As we move towards the final release at the end of this month I will now be updating the documentation to reflect the changes in 14.

* Mouse click action will set the Cut button to Prv for all actions other than Preview.
* Fixed issue with certain symbols in passwords when using CDNs such as ScaleEngine
* Fixed bug with SelectIndex shortcut for virtual sets
* Fixed bug with Solo indicator remaining on when removing input
* Onboard deinterlacing on Magewell cards is now automatically disabled
as vMix supports automatic deinterlacing internally.

FFMPEG Streaming Updates

* Added support for multi bitrate streaming with FFMPEG
* Added a "User Agent" option in the Streaming Advanced window
as some providers such as USTREAM require this to be set to "Wirecast"
in order for it to work correctly with Multi Bitrate.
* Supports up to three separate streaming providers if multiple bit rates are not needed.
To use this feature:
1. In the streaming window click the [..] button next to URL
2. Type in each URL one per line
3. In the streaming window click the [..] button next to Stream Key
4. Type in each Stream Key / Name one per line
5. Click the cog icon next to quality
6. Set the bit rates and sizes for each of these streams and check the boxes to enable them.
Usually, the bit rates and sizes will all be the same

* So far I have tested FFMPEG Streaming with USTREAM and Wowza (which many providers use). I would be interested in hearing feedback
on other providers users have been testing it with so I can add them to a supported list in the documentation.

Also works fine to DaCast, both the Flash (Edgecast) streams and HTML5 (Akakmai).

Thanks Martin,

Now testing 14.0.0.72.

We have tried FFMPEG streaming to Solidtango for 4+ hours, works fine. And YouTube for about an hour, works fine too.

But our test with Bambuser did not go so well. vMix reports starting the stream, but Bambuser's control/player page does not show any stream, or that anything is live. Tried 2.5 and 1.5 mbps. Checked with their support that AAC is supported. Then tried streaming with v13, FMLE and Main concepts AAC plugin, works both with 1.5 mpbs 96 kb audio as well as 2.5 mbps and 128 kbps. (Sidenote, another strange thing with Bambuser is that when we v13 click "Stop" streaming, it takes about 20s (and vMix freezes) until the red stream light turns off (and vMix responds again).

If you would like to test Bambuser I can PM you our RTMP credentials. (I know the Bambuser team, and can assist you in getting in touch with them if you think an e-mail to support@bambuser.com is not sufficient).

Also, the v14 stream log windows just rolls away for FFMPEG streaming. Would be useful if one could scroll and/or copy the text or get a log file from the streaming session.

Cheers.

UPDATE: You might consider adding Bambuser and Solidtango to the predefined list of CDN:s. That would require a little bit of API handshaking, no big deal I guess...

Super!

I was blown away by the new feature to send to multiple streaming providers. Only had time to check with two, but they worked nicely.
Noticed that if I then removed one of the URL lines, keeping the two stream key lines, I could start the stream and got no warning. (never checked if any or both streams actually became live).

Perhaps too late for the upcoming release, but in the future it would be nice with a somewhat developed UI for multiple stream settings. Meanwhile, since the URL and stream key are specified in the lines windows, maybe the URL and the Stream key in the Streaming Settings window could display "Multiple" if that's the case. Would be a useful reminder/warning for the operator.

I think it also would be useful if the possibility to stream to multiple streaming providers was more clearly described in the help. Currently it is sort of hidden under the URL and Stream key sections in the "Multiple Bitrate Support" page.

See the help file here:
http://www.vmix.com.au/h...reamingMultiBitrate.html

You need two URLs and two keys. Enter them into the URL and Stream Key fields separated by a ; with no spaces.
Then the bit rates for each need to be checked and configured in the Quality settings.

What settings are you using? Are you sending multi bitrate or separate streams?
Note with Akamai etc, multiple stream keys will need to be entered, separated by a ;

Thanks.. Yes now working. Should have thought of that!

Another thing...not a bug, but Avast keeps trying to analyse FFMPEG.exe and hangs on it. I also have the same file installed with other applications and it does not display the same issues. My simple workaround is to turn off the virus scanner (which is what I normally do when streaming anyway)

What codec is being used in the MXF?
Are you able to upload a sample MXF and email it to us? (info@vmix.com.au)

In the Input Settings window in the Deinterlacing box it should say "Interlaced UpperFieldFirst" if it is decoding correctly.

When I set the resolution, both in settings and external output, to 1080i50 it seems much better. It handles the interlacing better and the jagginess is almost gone. Weird, cause the MXF-files are SD.

I don`t have that option in the input settings? Only have a box that says "video is interlaced" which i can tick on/off..

It`s mpeg2, I`ll send you a sample tomorrow.

Think i will be producing the stream tomorrow in HD. Seems like thats better..
