The script is nothing to write home about at the moment, with most of my time being spent just dialing it in for performance given the age of the Thinkserver. I feel that's pretty squared away, so the next step is updating it to accept args for things like fps, resolution, etc.

#!/bin/sh

AUDIO_DEV="hw:CARD=HDMI,DEV=0"
FPS=60
OUTDIR="/home/wesker/capture"
PREVIEW_URL="udp://netsphere.lab:5000?pkt_size=1316"

exec ffmpeg -hide_banner \
  -thread_queue_size 2048 -f v4l2 -input_format yuyv422 \
    -video_size 1920x1080 -framerate "$FPS" -i /dev/video0 \
  -thread_queue_size 2048 -f alsa -i "$AUDIO_DEV" \

I settled on the Magewell card because I found one super cheap, their Linux drivers seem pretty well supported and maintained, and I wanted a bolted-in solution since everything is rackmount.

I paid $50 on ebay for the Magewell, because the seller had a huge lot of them to liquidate.

The TINK 4k is indeed expensive, but it was one I had laying around collecting dust. I have a museum of gaming consoles and for a while was upscaling them with the TINK, before moving on to a different solution.

The 16:9@60 is simply my not yet having implemented conditions in my script for variable capture settings. I am fortunate to have an 8TB HDD in the server, and an additional 140TB data server, so file size footprint isn't currently high on my priorities.

Not sugar.

Toast, eggs, and the noses of my enemies.

I was referring to us.

It's a sick world out there, and they've all congregated on lemmy.

Is this slop or spergposting? One answer gets a block; the other gets a block, but it's not personal, I just don't understand.

Older Reddit was even better. Reddit circa 2014 I was organizing local singles nights and smashing it.

I already have a Thempresse 3. Makes a great cup of coffee.

Thank you. He's shuffling to the kitchen for a cup of coffee.
