[FFmpeg-user] ffmpeg captures from /dev/video1 in any resolution EXCEPT 1920x1080

Hi folks,

Any help greatly valued.  Basically the problem is that ffmpeg won't
capture 1920x1080 on my Linux system, whereas other video capture
applications will, and yet ffmpeg will successfully capture other
resolutions from the same device on the same system.  Weird.  I've tried
many combinations of ffmpeg command lines and muttered many incantations
but none of them fix the problem.

I am using ffmpeg on Ubuntu 19.04 desktop on a Ryzen 2200G with 16GB RAM.

My goal is to create an  H264 mp4 video that can be displayed in a web
browser, with data sourced from a USB UVC device.  The resulting file
should play OK in the quicktime player on Windows and in a web browser.

Fact 1: ** I have an HDMI UVC to USB device which is capable of 4K video
input.
Fact 2: ** ffmpeg works fine when I capture video using ffmpeg in any
resolution EXCEPT 1920x1080 -
Fact 3: ** ffmpeg also works fine capturing 4k input as well as all the
lower resolutions
Fact 4: ** gstreamer seems to be able to capture data - it created a
gigantic file (see APPENDIX 1 output below)
Fact 5: ** Ubuntu's desktop guvcview program has no trouble at all
displaying video from the uvc device and needs no special configuration to
do so.
Fact 6: ** I used Ubuntu's desktop guvcview program in command line mode to
capture video from the uvc device in 1920x1080 and it handled it fine
