Convert input gray16le to RGB output stream

I'm reading a v4l2 format input video with pixel format gray16le from a USB camera connected to my computer. I can display it without problems.



My question is that I want to read that video with ffmpeg (on /dev/video0) and stream it to a websocket. If I read a "normal" rgb video, this is the command that I'm using to accomplish it:



ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -c:v mpeg1video -f mpegts https://......


When I try to read from the gray16le format camera, I've tried lots of commands but the output is always in grayscale. For example:



ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -pix_fmt yuyv422 -c:v mpeg1video -f mpegts https://......

ffmpeg -f v4l2 -i /dev/video0 -framerate 9 -pix_fmt rgb24 -c:v mpeg1video -f mpegts https://......


Is there an option in ffmpeg to apply a colormap or a LUT to the input video before streaming it?



Thanks!

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
