I've been having an issue with my Ezcap 269 refusing to switch to YUV capture mode despite me connecting to the USB 3.0 port. Has anyone else had a similar experience?

I've also gotten myself an ezcap269, to use with my Shield TV (2019) and Philips 43PUS6503 TV, as I want to be able to watch 4k60 hdr and run Hyperion on a third device.

Now, everything sort of works but the ezcap does seem to provice some problems. I know this forum is about Hyperion, but it's one of the few if not the only place of active discussion regarding the ezcap269.

When I play for example Netflix on my Shield through the ezcap to the TV, I get 4k60, HDR10, rec2020/yuv420 video as reported by the TV. So far, so good. When I try to capture something from the ezcap, the Shield reduces video quality to either one of these..

1080p59, HDR, RGB
4k30, HDR, RGB
4k60, SDR, RGB

If I stop the capture and restart both the shield and the TV, it will again resume 4k60 HDR playback.

The ezcap is (for now) connected to my Ubuntu 16.06 laptop, when I hook it up to my Win10 desktop (because I thought it might have been lacking power) it actually immediately downgrades the quality without even turning capture on.

So in short: 4K60HDR throughput works fine if the pc's not doing anything, enabling capture reduces the throughput quality.

What's up with that? Or is this 'normal' behaviour? I have updated the firmware, although I find it hard to see to what version exactly..

Edit: I have also found that if I hook the ezcap up to power only, it's max throughput will be 1440p60, which is lower than when it's connected to my (not-capturing) Linux laptop..

I seem to be having a problem with my nvidia shield too - it starts off fine at 4k SDR, but once I try to run HDR through it, it downgrades to 1080p.

I've emailed the company to see if they have a firmware update... It seemed to work fine when I was using Odroid C4 running CoreElec.

Anyway, with v412-ctl --all command, it give:
-bash: v412-ctl: command not found

How did you install Hyperion?

The easiest way is probably to download Awawa's compiled releases with wget then install with dpkg.

Ok quite the same of mina.... so you can't tell me how to configure the ezcap in the hyperion ng web gui

It's automatically detected for me and working out of the box... not sure how I can help you.

Can i ask what kind of grabber you own? I have an ezcap269 with apa102 but i'm still trying to make it funcion
In the hyperion ng web gui i can see the screen preview, but leds are always off...

My setup is:

• Raspberry Pi 4 running rasbian buster lite
• Compiled Hyperion.ng branch from Awawa's github (I think I did it correctly)
• ezcap 269 connected via usb 3.0
• Odroid C4 running CoreElec with SDR to HDR tone mapping enabled

I haven't got my led strip in yet, but plan on using WLED.

Seems YUY2 HDR capture is working for me!

How do I know if I'm using YUY2 or MJPEG encoding? Otherwise, the colours seem to work great on the live video feed. Waiting for my LED strips to come in.

hidden '.hyperion' home folder.
e.g. '/home/pi/.hyperion'

Thanks, I figured it out! Still new to Linux.:oops:

Hey Awawa, while I was playing around with the Pi while my Ezcap arrives, I was trying to find the folder with the Hyperion config, but I couldn't find it. Do I have to create it?

Looking forward to the Pi4 build!

Thank you Awawa - HDR support was the one thing stopping me from setting up Hyperion but your work has brought it closer to reality! Ordered an Ezcap immediately after looking through this thread!
