how to use ffmpeg to encode videos with hsv colorspace

Selection: crop_default, Left 0, Top 0, Width 1920, Height 1080, Flags: Quantization : Default (maps to Limited Range)īounds : Left 0, Top 0, Width 1920, Height 1080ĭefault : Left 0, Top 0, Width 1920, Height 1080

YCbCr/HSV Encoding: Default (maps to ITU-R 601)

Transfer Function : Default (maps to sRGB) 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.Īppendix 1: the uvc devices ls /dev/vid*Īppendix 2: uvc device info v4l2-ctl -all.Ubuntu's desktop guvcview program has no trouble at all displaying video from the uvc device and needs no special configuration to do so.gstreamer seems to be able to capture data - it created a gigantic file (see APPENDIX 1 output below).FFmpeg also works fine capturing 4k input as well as all the lower resolutions.FFmpeg works fine when I capture video using FFmpeg in any resolution EXCEPT 1920x1080.I have an HDMI UVC to USB device which is capable of 4K video input.Here are some facts about my setup and known usage: The resulting file should play OK in the quicktime player on Windows and in a web browser. 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. I am using FFmpeg on Ubuntu 19.04 desktop on a Ryzen 2200G with 16GB RAM.

I've tried many combinations of FFmpeg command lines and muttered many incantations but none of them fix the problem. 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.
