• Accessing RTSP Server hosted on AWS over internet

  27 juillet 2018, par Kishor V

  I am trying to access my EC2 Ubuntu instance from AWS using gaminganywhere (gaminganywhere.org). The security group policy is to allow all connections, but couldn’t connect to the server. Here is the log from the client and server.

  I think the IP address in RTSP header is the LAN IP of the device which is causing the making the connection to fail. The same software works fine from the LAN. Any help is appreciated.

• Launch Symfony 4 command from controller works on dev but not in prod environment

  14 août 2019, par JoakDA

  When an application loads, I make 2 AJAX request to start 2 proccess needed for showing a RTSP video streaming on the website.

  It is working great in DEV environment but making some tests in PROD, it only works if the page is loaded on the server webbrowser (same host where the application is installed).

  If I use an external browser installed on another machine, it doesn’t launch the video.

  I am using PHP 7.3 and Symfony 4.3

  I am able to get a successfully response from the controller but I can’t watch the video streaming on an external computer.

  UPDATED : I don’t know if it may be related to the issue, but when I switch to DEV and then switch again to PROD using :

  composer dump-env prod

  If I try to clear the cache with :

  php bin/console cache:clear

  It appears :

• ffmpeg mp4 x264 encoding -> playback causes "pending" in both Chrome and IE causing 10+ seconds delay

  26 novembre 2015, par user1978645

  After encoding a video to mp4(x264 with aac) ; I have the following weird behaviour in both crome and IE :

  Im serving the content from https with spdy enables.

  It takes up to 30 seconds before the video is actually played, in the mean time i cannot reload the page it shows up as "pending". (even after i have visual on the video sometimes it takes 10-20 seconds before i can actually reload the page, or navigate to another url on the same domain)

  After looking at the "network" tab in developer tools, i see the following requests for 1 page/video :

  Path        Method Status   Type         Initiator   Size/content  Time/latency
  
  video.mp4   GET    206 OK   video/mp4    other       32.3KB/32.0kb  600ms/339MS 
  
  video.mp4   GET    206 OK   video/mp4    other       123kb/123b     21.85s/21.46s
  
  video.mp4   GET    206 OK   video/mp4    other       7.1MB/7.2MB    1.4min/2ms

  I tried to isolate the problem, When i use an mp4 video from the internet (for example the demo video of jplayer) and load it from my server, it loads rapidly, without delays.

  So it makes me think the problem lies within the encoding. I tried various things.
  FFmpeg :

  • csr 69 (low quality)

  • various options

  HTML :

  • preload="none"

  • javascript loading/playing of the movie

  • type=’mp4/video’

  • no posterimage

  But i cannot resolve the problem. Does anyone have a clue what is causing this ?

  I have a download speed of 300kb/s and the movie is 6MB.

  After the video starts, the video isn’t fully buffered, so i wonder : What is the html5 videoplayer doing all this time ?

  The problem also blocks the connections. When i press "F5" in both chrome and IE the page beeing reloaded comes up in the network tab as "pending" and it can take 10 to 20 seconds before the page actually reloads.

  ffmpeg command : (i used various commands but this is just 1 example which causes the problem)
