Hi,

I have tested

  • two different converters:

https://www.ebay.co.uk/itm/Mini-Portable-USB-2-0-Port-HD-1-Way-HDMI-1080P-Video-Capture-Card-For-PC-Laptop/142907175902?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

and

  • two different HDMI cables
  • two different computers to output HDMI (PC with GTX1070 and Macbook Pro 2014)
  • Raspberry Pi3 B+ with latest Raspbian Stretch 9 (Linux raspberrypi 4.14.50-v7+ #1122 SMP Tue Jun 19 12:26:26 BST 2018 armv7l GNU/Linux)

I've got the same result by using any of these converters and cables.

I'm using mencoder command to record test.avi and the output is almost not visible because of many green lines and glitches:

40517727_2246338448931231_4390862817524187136_n

This is a mencoder command which prints some drops (14 frames successfully processed, -10 frames dropped):

Can you see guys causes for an issue or do you need more details? I really appreciate any comment on that - thanks!

I have found that removing modules-load=dwc2 from /boot/cmdline.txt and dtoverlay=dwc2 from /boot/config.txt seems sorted the root cause in my case. I came to idea to remove this because of [253805.452822] dwc2 3f980000.usb: dwc2_hc_halt() Channel can't be halted error in dmesg.

I still have two issues that

  1. video quality is not good enough to see very small fonts (it's like 30+ years old TV display)
    I still see the error buffer contains corrupted data when using ffmpeg or avconv tools manually

  2. lower corner of screen is not visible through web server (so when I'm in the Linux console, I don't see few last lines what I'm typing in) - I have also checked the jpg file in /mnt/ramdisk to confirm that it's not web interface and css styling issue

Not sure whether these next issues are related with original issue at the moment

I wanted to share a resolution.

An second issue solved by changing avconv -f video4linux2 ... to avconv -f v4l2 -standard pal ... in /var/www/html/image.php so it fits into the screen now.

Video/image quality still could be better, but decided to not invest time on this issue.

Unfortunately, analog video has a very low quality.
From my past experience there are EasyCap devices that use bad qualiy ADC chip, device looks the same but different chips inside.
The Amazon link provided should be the better quality one.

You can research more but I think the best way is going fully digital, you can check issue #6 for alternatives.

Thanks for useful info. Did you mean the amazon links from README.md? If I remember correctly I had some difficulties to get this in the UK with limited time and also found that "HD Capture" doesn't require a separate powering so I bought that one.
Do you know whether these devices in README.md support resolution such as 1024x768 or at least 800x600?

Do you have some examples of digital solutions? Are they sold only at higher prices comparing with EasyCap devices?

I have attached the photos of "HD Capture" and lsusb output (not sure whether this is ADC bad quality chip):

Many thanks if you have a few minutes to reply this

@laimison refer issue #14 for an interesting "hackish" way to capture HDMI signals with minimal budget if you would like to upgrade your quality.

About the cloned devices, I meant the Easycap device.
But anyway you can't expect much from those cheapo product.
The downscaling from HDMI resolutions, to analog TV resolutions like S-Video will give you approximately the equivalent of 640x480-800x600 resoluion.
Text won't be sharp in this technology unless higher quality analog-to-digital and digital-to-analog converters are used.

Best option is to use an all-digital path as I mentioned before.
