Acting as a WHIP forwarder
This example requires port 5000 UDP to be open for inbound traffic

$ donut ./donut -whip-uri https://galene.pi.pe/group/whip/ -srt-uri "srt://0.0.0.0:5000?streamid=test" \
-whip-token ${bearertoken}
You can then send multiple SRT streams to be forwarded as WHIP examples: Camera from a mac:

ffmpeg -f avfoundation -framerate 30 -i "0" \
-pix_fmt yuv420p -c:v libx264 -b:v 1000k -g 30 -keyint_min 120 -profile:v baseline \
-preset veryfast -f mpegts "srt://${bridgeIP}:5000?streamid=me"
Or from a raspi

ffmpeg -f video4linux2 -input_format h264 -video_size 1280x720 -framerate 30 \
-i /dev/video0 -vcodec copy -an -f mpegts "srt://${bridgeIP}:5000?streamid=picam"
Idea for dedicated stream/grabber:

https://github.com/giongto35/cloud-morph/wiki/Deep-Dive-Into-Codebase

[program:Xvfb] command=/usr/bin/Xvfb :99: Create Virtual Video Buffer at port :99
[program:pulseaudio] command=pulseaudio: Create Virtual Audio (pulse). Don't need to bind to any port, app still can output audio to it.
[program:syncinput] command=wine syncinput.exe : Script to listen from Web Message to simulate Windows OS Event
[program:wineapp] command=wine %(ENV_appfile)s environment=DISPLAY=:99 : Run Wine app and attach virtual DISPLAY :99 to it
[program:ffmpeg] command=ffmpeg -f x11grab -i :99 -c:v libvpx -f rtp rtp://%(ENV_dockerhost)s:5004 : Video encoding read from Virtual display and export Video RTP stream at port 5004
[program:ffmpegaudio] command=ffmpeg -f pulse -rtp rtp://%(ENV_dockerhost)s:4004 : Audio encoding read from Virtual Audio and export Audio RTP stream at port 4004

you can freely parse FFox .sqlite bookmarks from linux terminal:

sqlite3 ./173iv6vo.default-release/places.sqlite .dump |grep youtube.com



where
173iv6vo.default-release

your FFox profile on the system

you can use
find . -name *.sqlite
to figureout all FFox sqlites
a very nice way to filter HTML or /and output to console:
links -codepage utf-8 -force-html -width 400 -dump /dev/stdin


or
links -codepage utf-8 -force-html -width 400 -dump /path/to/html/file.html
a fast way to get serial (and others things from udev):

udevadm info --query=all -n /dev/sda
FFmpeg near precision way to cut video (pt1):

ffmpeg -i planes.mkv -ss 00:00:05.000 -t 00:00:05.500 plane0505_recode.mkv


check timing by:
ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 plane0505_recode.mkv
FFmpeg stress test:
(it will load all cpus)

ffmpeg -y -f rawvideo -video_size 1920x1080 -pixel_format yuv420p -framerate 60 -i /dev/urandom -c:v libx265 -preset placebo -f matroska /dev/null
Random noise from /dev/urandom:

ffmpeg -f rawvideo -pixel_format rgb24 -video_size 1920x1080 -framerate 120 -i /dev/urandom -c:v libx264 -preset ultrafast -pix_fmt yuv420p output.mp4


Keep eye on filesize.
