Hi
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 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

[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
Andy
