I'm using vMix 23.0.0.57 for a very small system with a single BMD HDMI input card.
Most of the imagery comes from NDI, or pre-recorded video files.

My test file is a 3.2 GB file created by Davinci Resolve using the vimeo settings.
I've used these settings for a year using OBS to encode them, but id like to move to a single box solution with vMix.

The hardware is a old HP desktop https://19216801.onl/ https://routerlogin.uno/ https://192168ll.link/ PC, with a quad core 2.8ghz processor, 8gb DDR3 RAM, 512GB SSD and a new GTX 1050 4GB.

I have successfully streamed without hardware encoding at 720 but i can't use 1080 because the load is too high on the CPU.

With hardware encoding, everything looks to be going well but vMix restarts.
the log file eds with:
[flv @ 051586e0] Failed to update header with correct duration
[flv @ 051586e0] Failed to update header with correct file size
frame=17906 fps= 25 q=28.0 Lsize = 115803kB time=00:12:00.68 bitrate=1316.3bit/s speed= 1x
video:103573kB audio:11319kB subtitle:0kB other streams:0kB global headers:0kB mixing overhead: 0.792891%
[aac @ 0515dc0] Qavg: 498.033


I've tried removing some overlays like the time and a ticker.
I've tried changing the encoding rates etc but they all have a similar crash. At least i think it's a crash.

Does anyone have any suggestions?
In my tests, there is 1 file input, one encoding output. I have 4 or 5 example logs if they will help.

thanks

Strange, three different users have exactly the same problem.
How many user names do you still have?
They all have the same problem. The third post!
