Usb Video Capture Device Not Working

[Nicodemo Aidara]

Iinstalled hyperion on Rpi 4 and have enabled the USB capture.But hyperion doesn't detect usb video capture when i go to the remote control tab of hyperion and nor can i see a live feed. My video capture device works fine as i checked it in OBS ...Can you tell me what to do?

I have noticed that the blue LED on my video capture device wasn't lighting up indicating a stable video input and Hyperion was not detecting the video capture device. I power cycled the video capture box including the 2 HDMI cables (as there is 5V power on the HDMI cable) and micro USB power and USB data cables.

in Terminal / created a new account / turned off screen time...still not working. This is not normal and apple should do something about it. They need to come up with a solution since it seams there is a bug somewhere. If for anybody worked something else, please post here. Thanks

It is my understanding from your post that your Mac is not recognizing your camera. I recommend testing the issue while your Mac is in safe mode and/or in a new user account. This will help determine the cause of the issue. The following articles have the steps you will need to test the issue in both safe mode and in a new user account:

I am having similar problem since May 12 2020( last used mothers day May 10th and was fine.) In my hardware list under camera it says "no video devices were found", and, for me, it also is not showing up in USB. Have Mojave 10.14.6

I spent hours trying all the classic fixes and thinking it was a privacy and security issue. Turns out in my case it had something to do with a Catalina 10.15.2 bug. It goes away once you update your OS. Hope this helps.

I am having the same issue. No green light. It started with face time but zoom was working. Now zoom isn't finding the camera either. I checked the system report and it says "No video capture devices were found" No trauma or damage to my computer (although plenty of trauma and damage to me if I cant use zoom or FT in 2020!)

I am having the same issue since the beginning of 2020 in my MacBook Pro 2017 Touch Bar I have contacted apple service in February they diagnose the problem and after 3 weeks they said they must change the whole screen first they say its under quality assurance but then they change and say I must pay 850 USD for the whole screen I refused. I guess its a manufacturers defect !!! hope to find a solution so that 2020 we can't use MacBook without camera.

Can someone recommend some HD/SDI video capture devices that are PXIe, PCIe, or USB -- that has LabVIEW drivers/VIs available? We have NI Vision Dev. But, we currently have to convert the HD/SDI to HDMI and then capture that on a StarTech USB3HDCAP and input to USB 3.0.

The main solution we use is BlackMagic's DeckLink series of PCIe cards for 720p, 1080p, and 4K 30Hz capture. They are compatible with Vision via directShow. We did have some issues with how Vision handled the cards and ended up writing our own LabVIEW wrapper for the BlackMagic SDK so your milage may vary. Another company to check is Pleora, they used to have a USB3 to HDSDI converter, but I believe it was discontinued. I don't know if they have plans for another version of it.

I had so many problems with the S3 on linux that Anker gave me a full refund and they where really great about as it had weird effects such as playback would take time to wake on Linux and miss short notifications whilst on windows it was perfect.

To circumvent the endless arecord: main:830: audio open error: No such file or directory error messages, I finally ended up installing PulseAudio on the host, and the error stopped appearing, and I was able to issue an arecord command. However, no audio seems to be recorded (but playback via aplay still works 100% of the time).

To break things down and just test out your Ankor (ps you a commdore 64 fanatic, them where the days )

Get a spare sdcard with a clean install and just install rhasspy docker and set up with sharing /etc/asound.cond as you do need the same IPC keys for the same device but all devices must be different.

You have to add the ipc=host or whatever it is and the -v /etc/asound.conf:/etc/asound.conf.

docker container ls -a and stop and delete the rhasspy container and run the docker run with the ammends from the thread I mentioned.

I have forgot totally what sample rates and channels it supports but its just the same as any usb device.

Alsa has such a strange format and poor documentation that I always end up testing and editing the pcms several times before I get it right but the above is from a working setup and all I can see is you changed from hw: to plughw on the dsnoop, where the only thing you may of needed to change is the channels.

Google has a short enrollment where it collects your voice and does something called targetted voice extraction and it stays focussed on you, that I think is part of the KWS and part of its local processing but that is just guess work.

A smart assistant mic and a conference mic are very different things and none really makes a smart assitant mic apart from those who make smart assitants, but by chance of testing the beamforming Webcam mics or built in tablet mic arrays work much better as the single user focus design is much closer to a smart assistant mic than a conference mic.

It will work when you eventually get the asound.conf right but its not really rigged up to cope with common forms of domestic media noise, but is great at removing constant background workplace noise which is a very different environment.

PS I took a closer look as it has been some time and with my specs on the model I had was the Powerconf, which makes sense as it was the 1st one they released.

So the S3 is prob OK and maybe I should plug mine back in and see if there is a firmware upgrade.

I got one when I was trying to work out alternatives but think I have better solutions as if you are going to have a maker project then you at least want to try and improve on Commercial product or at least provide that artisan maker quality that they can not provide.

Even with the deals on the S330 of 39% off my preference would be to get a pair of 2nd user nice bookshelf speakers off ebay for 20 -30 and because I am an audio snob Sure Electronics do these really great Amp boards for about 35 that yeah prob I could get much cheaper.

There are software algs and some laterial thought to engineering that if you stop just trying to copy commercial units and concentrate on a solution you can recycle ewaste and create an extremely capable modern room AV/Wireless audio/smart assistant system.

I have been an audio snob as there are cheaper amp boards but the biggest noise problem in a residential situation is third party noise via media such as HiFi & TV and I can intergrate that at low cost that is not much difference to your spend even with my snobby audio choice so I have total control and also make it sound great.

@C64ever My original Powerconf has been gathering dust for so long, I can not remember. I would of had a Pi4 at the time but think I was dual booting my x86 workstation as Anker where great and was communicating with them that on Windows fine, Linux not so.

If I tried on the Pi after that I dunno but maybe not, C64ever has been using the newer S330 model and will be able to tell you.

So I have the same problem (I think) and this is all very new to me.

I have an Anker Powerconf S330 connected to my Raspberry Pi running RaspberryOS Lite with Rhasspy in Docker.

It will record with arecord but times out with PyAudio. What do I need to do to get it working?

Premiere Pro is not seeing my Canopus Firewire capture device. I do not want hdv because it is DV. If Premiere does not see the Capture device, it does not matter what camera is connected to it. It would at least see the device.

I have been trying to get my USB capture device working with FFMPEG 6.0 so that I can have a little more flexibility than OBS offers. I have been running in to some issues with the framerate at any resolution, and even when copying the raw video stream. I do not believe this to be a problem with my capture card, because OBS records from the device at full 60 FPS at 1920x1080.

My current theory is that perhaps my USB capture device has a switchable output (I have heard that some capture devices can output raw video or MJPEG and switch between the 2) but 1 of the outputs is low framerate.

What you are receiving from TVTime is a wrong redirection to the appropriate device, which is leading tvtime to /dev/video0, if you are having a webcam, usb plugged or embedded then tvtime is trying to acquire images from the webcam instead of the TV Tuner. Try changing this value with /dev/video1, /dev/video2 or whatever it works for you.

I have the Hauppauge HVR-1250. The HVR-1250 has the Conextant CX23885 drivers. It works out of the box for digital ATSC tuner capture with Ubuntu 12.04 LTS, which has kernel 3.2.0. In the /dev folder it shows as /dev/dvb. The analog capture (for the composite and S-Video, not the analog tuner) is supported in kernel versions 3.5.5 and above. I installed kernel 3.5.5 in Ubuntu 12.04 LTS and I can record Digital HDTV OTA from my antenna and analog capture from my cable receiver box via the composite cable. The analog driver shows as /dev/video0 in the /dev folder.

I have a Pavilion dv7-6157nr Windows 7, 64 bit machine. I installed an Honestech VidBox 3 video capture device and VHS to DVD software on the laptop. This VidBox was working on my Windows 7, 64 bit system but suddenly stopped working. I installed it on an older computer with Windows Vista 64 bit and it worked just fine. Since the VidBox worked on the Vista system I uninstalled the VHS to DVD software and VidBox driver from the Windows 7 system and ran cCleaner on my registry. I then reinstalled version 5.0.29 VHS to DVD software first, rebooted and then reinstalled the version 3.0.6 VidBox driver and rebooted. I then plugged the VidBox hardware in to be sure it was recognized. I then started the VHS to DVD software and made sure it was set to use the VidBox on composite NTSC_M and started the VHS tape playing. The VHS to DVD video screen was unresponsive and completely blank. While I got no error messages the traditional black window didn't even show up in the VHS to DVD software. I did, however, get audio.
