Simple Cloud-Base Low-latency HLS

Components:
    - HLS Generator: To transcodes/transformat/segment input stream 
    - Redis server: As DB of HLS segments and streams info
    - HLS server: To generate playlists and serve segments from redis
    - Nginx server: To have TLS, Cache, .. (Optional)

Dependency

Clone and make this source on third_party folder:    
    - C++ wrapper for ffmpeg:  https://github.com/h4tr3d/avcpp.git 
    - C++ REST API library: https://github.com/meltwater/served.git 
    - Redis client library: https://github.com/redis/hiredis.git

Usage

API

Get playlist of all live streams in system:
curl http://ip:port/v1/cs/play/llhls/lives_list.m3u8
It contain master playlist for each live 

With Docker

- HLS generator for any input:
docker run --network host            \
    -e INPUT_URL='rtsp://ip:port'    \
    -e REDIS_HOST='127.0.0.1'        \
    -e REDIS_PORT='6379'             \
    -e REDIS_PASS='123123'           \
    -e OUTPUT_PROFILE_1='original'   \      # without transcoding
    -e OUTPUT_PROFILE_2='SD'         \      # resolution 720x438
    -e OUTPUT_PROFILE_3='CD'         \      # resolution 320x240
    hls_generator

- Redis server:
docker run  -p 6379:6379             \
    -e REDIS_PASSWORD=123123         \
    bitnami/redis:6.2


- HLS Server:
docker run --network host            \
    -e REDIS_HOST='127.0.0.1'        \
    -e REDIS_PORT='6379'             \
    -e REDIS_PASS='123123'           \
    -e HLS_SERVER_PORT='8088'        \

TODO:

- Support HLS base functionality
- Support Adaptive bit rate
- Support Low-latency features: 
    EXT-X-PART-INF
    EXT-X-PART
    EXT-X-PRELOAD-HINT
    EXT-X-RENDITION-REPORT
    EXT-X-SKIP
- Improve performance:
    Decrease memeory copy operations
