====HLS====
===gstreamer/video.js===
the easiest stream i got was using hlssink
gst-launch-1.0 videotestsrc is-live=true ! x264enc ! mpegtsmux \
! hlssink playlist-root=https://your-site.org \
location=/srv/hls/hlssink.%05d.ts \
playlist-location=/srv/hls/playlist.m3u8
and video.js on the other site
pipe video from rtsp ueye
gst-launch-1.0.exe rtspsrc location=rtsp://169.254.37.87:8554/mystream ! fakesink ! fpsdisplaysink
===Javelin===
[[https://gitlab.com/valeth/javelin|gitlab javelin]]
install rust on server
curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
you'll probably need a few deps, like
sudo apt install libssl-dev
cargo install javelin
# add an user with an associated stream key to the database
javelin --permit-stream-key="idiotstream:cc144117a8fe59af0f7f34ce9eca8f05" --rtmp-bind 46.101.213.56 --http-bind 46.101.213.56
# start the server if not running
javelin run
couldn't get server/client to access 8080 to see the stream . trying the docker-compose way

===Kinesis===
**Q: What’s the difference between Kinesis Video Streams and AWS Elemental MediaLive?**\\
AWS Elemental MediaLive is a broadcast-grade live video encoding service. It lets you create high-quality video streams for delivery \\
to broadcast televisions and internet-connected multiscreen devices, like connected TVs, tablets, smart phones, and set-top boxes. \\
The service functions independently or as part of AWS Media Services.
Amazon Kinesis Video Streams makes it easy to securely stream video from connected devices to AWS for real-time and batch-driven machine learning (ML), \\
video playback, analytics, and other processing. It enables customers to build machine-vision based applications that power smart homes, \\
smart cities, industrial automation, security monitoring, and more.
