vladadrian/janus repository overview

###Config There is only one file that is used as input for the application and it's called streaming.yml. This a yaml file that has the following structure:

limit_disk_space: maximum amount of bytes that the recordings will occupy
camera:
  <name1>:
    src: "rtsp url to the live stream of the camera"
    rtsp_transport: "tcp" | "udp". Default: "udp". Some rtsp streams don't work on udp. Setting this option to "tcp" might help
  <name2>: ..
  <name3>: ..
  ..

###Run

docker run --init --rm -v <path_to_directory_containing_streaming.yml_file>:/opt/streaming -v <path_to_directory_that_will_store_the_recordings>:/opt/static/recordings --net my_net janus

###Endpoints

• /live/<id> - shows live view of the respective camera. id is an int that corresponds to the index of the respective camera in the streaming.yml's camera array.
• /static/history.html - the page where past recordings can be viewed.

⁠TODO

• vazut cum detectam ca ffmpeg nu mai inregistreaza sau s-a blocat

• un stream mai mic separat pentru live

• history.html:312 Uncaught DOMException: Failed to set the 'playbackRate' property on 'HTMLMediaElement': The provided playback rate (26.889) is not in the supported playback range. at HTMLVideoElement.UserInputVideo.video.doUpdate (http://192.168.111.12/static/history.html:312:31⁠) at updateAll (http://192.168.111.12/static/history.html:833:41⁠) at Timer.updateSecond [as oncomplete] (http://192.168.111.12/static/history.html:668:5⁠) at Timer.step (http://192.168.111.12/static/history.html:473:22⁠)

• schimbat culoarea la iteme in ceva mai contrastant (poate rosu)

• filtrare dupa anumite eventuri

• culori :

  • video #85d8a6
  • event #195f2f cu scris alb
  • folosit className pentru schimbat stilul si culorile

• in major label sa puna si urmatoarele doua unituri

• adaugat moment.js si vis.js in static si vazut bundle-ul cu ele doua

• in video-ul de la shinobi a lui spaceinvader unul din mount-uri e rw-slave

• configul trebuie montat RO

• cand porneste face sync disk->db

• in rulare foloseste doar db ca sa ia decizii

• poate baza de date pusa separat

• folosit timezone; data de la numele fisierului e in utc, dar in pagina se arata in Bucharest/EastEurope

• vazut ca video-urile sunt continue perfect (merge-uit doua video-uri cu bunny)

• folosit logging

• in recorder prins erorile de pe stderr si pasate in logger

• favicon la history.html

• numele de camere nu tre sa inceapa cu _

• pus udp si 900 in default.py

• remove old events

• remove empty directories

• default -> constants

• verificat ca e timp destul pentru ca recorderul sa se opreasca

• elementele stackabile cu un buton de enable/disable

• add example streaming.yml file

• make live video resize with the page

• vis.js performance

• de vazut ffpmeg multithreading daca poate sa accelereze crearea de segmente ca sa nu mai ramana spatiul de aproape o secunda intre segmente

• se poate muta axa in partea de sus si la fel si itemele: orientation: 'top'

• should record fragmented mp4 to avoid file corruption if the recording machine is suddenly powered off:

  • movflags=frag_keyframe+default_base_moof+empty_moov+separate_moof
  • fragmented mp4 video file in "video" tag is slow to start in Chrome. Firefox works better. Probably because Chome wants to read all the moof atoms before starting playing. Link to test: https://happy-testing.s3-eu-west-1.amazonaws.com/stack-overflow/help.mp4⁠
  • for the above reason, we should try to make this project work in Firefox
