Submitted the hang diagnostics above earlier. Starting locally per @turtletank 's workaround works.
My client issue with pausing only seems to be impacting my ipad - submitted client diagnostics there (1f0d1bc8-0ec8-4a17-a2fa-1e262a5f1043 ).
My iphone client worked without issue, so thinking it's maybe something with my (older and space constrained) ipad.
Also submitted d6244621-bba5-464e-b42e-69f11811f3ff from the local start.
Having trouble with Ubuntu Linux, just trying to test the capture before setting up with AH4C or ADBTuner.
I am using the capture card referenced in the first post from Amazon.
The m3u I’m using:
#EXTM3U
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture
capture://v4l2/video0
Output of v4l2-ctl --list-devices:
rice@amd:~$ v4l2-ctl --list-devices
USB3 Video: USB3 Video (usb-0000:08:00.0-5):
/dev/video0
/dev/video1

I’m able to successfully test capture and playback using:

I’ve tried a lot of different m3u texts and I think I need to give the fetching guide data servers a break. I also feel like the capture is hanging behind the scenes and never releases the capture device.
New diagnostic log submitted under a04dc029-de50-4682-ad41-2a856d137a15
Hmm, this is what I see in your DVR log:
2025/02/25 17:15:06.796877 [HLS] ffmpeg: capture-usb-hdmi: [video4linux2,v4l2 @ 0x428cf640] ioctl(VIDIOC_DQBUF): No such device
2025/02/25 17:15:06.796880 [HLS] ffmpeg: capture-usb-hdmi: /dev/video0: No such device
Wonder if it is a permissions thing? What does ls -alh /dev/video* show? What user is the DVR running as?
It’s possible that was from when I yanked the card out of the usb port because my testing was showing it was in use and never lets it go.
rice@amd:~$ ls -alh /dev/video0
crw-rw----+ 1 root video 81, 0 Feb 25 17:15 /dev/video0
User rice in the home directory
Looking back at the logs that is indeed when I pulled the card from the usb port because I was getting device or resource busy.
Should the m3u capture://v4l2/video0 have /dev in it? I think I tried it that way but got errors
The /dev/ part is not required. I didn't really test this on Linux yet.. sounds like it needs more work.
@hancox can you try this on macOS DVR Pre-Release Notes - #1680 by fancybot
no real change, unfort - still hangs on normal start on iOS client

This is great. I always wanted to try the LinkPI products to pull in YTTV channels into Channels DVR, but it was too expensive for what I would gain.
I use a Synology NAS as the Channels DVR server. I assume that I need to purchase USB to HDMI capture cards, but they need to be setup on my Windows PC and not directly into the Synology NAS, correct? Is there any other way to get the USB to HDMI devices onto the network instead of through a PC? I'd rather not run both the Synology NAS and the Windows PC. Any other options?
Couldn't you use the linux option since DSM is like Linux?
Synology works great for me. I bought some hdmi encoders and onn boxes and they work great.
Unfortunately that's above my head.
The HDMI encoder approach is what I wanted to try, but again it's a pricey buy in.
I have thought about purchasing the capture device.
I have a windows device on the network.
The 2 hdmi encoders i've setup are working great.
I have bought the capture card recommended from Amazon. I cannot get it to work with this using Linux
#EXTINF:-1, channel-id="usb-hdmi",USB HDMI Capture
capture://v4l2/video0
However I am seeing video when I follow this print

From this article
Found one of the links above for USB Capture Devices has "Used - Like New" listed for $11.25 if you are looking for low investment for testing.
I got this capture dongle today. (Amazon Vine program)
https://www.amazon.com/dp/B0DQ59PPS5?tag=channels04-20
It supports much more than the other older "Game station" style capture device.

Got it working fine in Channels at 2160x1440 30fps.
Input latency is still a huge issue, 3sec a min . But, audio/video sync looks good.
NOTE: Not sure if related to recent pre-release updates, but ffmpeg.exe will not work, "Not a valid win 32 application". Had to replace it with .exe from a couple versions back. (i made a separate thread on that.)

Thank you, it's working now
Great thanks, I can see video now, though its choppy. Dropped resolution down to 720 which helped it a bit but I think my hardware is limited on a raspberry pi 4. Can't hear any sound but this is in the log

Many thanks
A Pi is not good enough this does Software Encoding Capture not hardware. Folks hanging on to a PI to run Channels DVR and Software HDMI Capture are trying to squeeze water out of a rock.
Low Powered Machines cannot do reliable Software Transcoding ... you would need to invest in a hardware Capture Device...
If you want the full potential Of Channels DVR and all the contributions from the Community, you need to move from Low Powered devices.
