Hello,

can somebody tell my exactly information about the advantages of the new feature?

* NEW Hardware Encoding support for Streaming (Beta)

When its an advantage, when better not to use and of course, how was it running since the last version?

Thank you!

I'd say it uses your GPU to offload the encoding for a streaming video.

Advantage, more CPU available for other tasks.

So would be better to use when you have a good GPU that's quite powerful and not good to use when you have a slow to average GPU (IE: Intel HD Graphics or most but not all Laptops).

I have not tried it, that is just what in theory I think of how you would use it.

Hello,

I just tried it and got an error. So I guess that is why it says (Beta).

The Error I get says:

Streaming

Stream #0:1 -> #1:1 (pcm_s16le (native) --> aac (libfaac))
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

My video card on the computer I just tested it on was a NVidia GeForce GT 520, so nothing special.

I can confirm it works with the right hardware! On my Asus GTX780TI-DC2OC-3GD5 3G it cuts the CPU usage on MP4's by around 60%. On an AMD Radeon 7700 it fails. Tested by streaming the same video at the same bitrate and framerate.

Ash,

Can you confirm vMix is detecting in the graphics card as 880M in Settings -> Performance?

If the system has optimus enabled, you may need to setup a profile in the Nvidia control panel
for the ffmpeg.exe program in vMix\streaming and tell it to use the dedicated graphics.

Ok changed the setting in NVIDIA Control panel to use High Performance NVIDIA processor still no change in error message. Also tried just setting ffmpeg in vMix\streaming to the NVIDIA but that did not work either.

I just picked up a EVGA GTX980, can't wait to install it and give this a try. Love to offload more processing to the GPU!

Does the hardware encoding also takes over the FMLE and FFMEG live streaming encoding?

Just had some time to install vMix 104 and had problems with not being able to assign vMix or any other application to the 880M card.

A bit of research led me to do this http://www.guru3d.com/fi...ninstaller-download.html

Worked like a charm and resolves the ffmpeg streaming problem I was having.

The problem was with the NVIDIA driver. Somehow was corrupted.

Cheers

Installed the GTX 980 today. The streaming ffmpeg process is only using 2-3% CPU now when using the graphics card for encoding. When can we get this going for the recording also? :)

Did my first show using the new Hardware Encoding. The ffmpeg process used for streaming ran around 2-3% CPU usage vs the normal 12-15%. However, a little past the 1 hour mark the Desktop Windows Manager crashed Vmix became unresponsive. Stopping Vmix and restarting, brought everything back to working and we ran another 40 minutes without an issue.

A few specs of my system in case it helps:

* CPU - i7 3770k
* RAM - 32GB
* GPU - EVGA GTX 980SC w/ 4GB of ram
* SSD for Boot drive, SSD for programs and SSD for recording
* 2 C920 webcams
* 2 AverMedia C985 video capture cards used to capture Skype video from 2 separate computers

I can't get this working (16.108).

On my laptop with GTX730m (not recognized in Performance setting, using default Intel HD graphics) Hardware encoding works!?!?

For the below I've tried with different streaming providers.

On another laptop GTX940m (set in Nvidias control panel to be default for all apps, recognized and used by vMix I get error (same as image below).

On a desktop GTX760 (only graphics card) it does not work either. Attached image, plus log below.
