HLS Server

[beasteers]

I added an initial container for the HLS server, however I'm having trouble getting it to work.

I have a test web app that attempts to load the video feed from the HLS server here: https://github.com/VIDA-NYU/ptg-api-samples/tree/main/web-webcam (npm start > localhost:3000)

but it always says failed response empty. clearly I'm not doing something right 😭

I was hoping to have it use exec_pull in the nginx config so that it will only stream to hls on demand, but even trying to stream directly to HLS from my webcam (bypassing redis) I was having trouble.

I included a python script that pulls frames from redis for streaming

# write to stdout
python hls/streams.py stream webcam:pv
# write to hls server
python hls/streams.py hls_stream webcam:pv
# show redis stream using opencv
python hls/streams.py show_stream webcam:pv
# push webcam directly to hls (no redis)
python hls/streams.py push_webcam_hls webcam:pv
