• Where to (long time) host Spring Boot Application with Data Base Backup and Linux Root Access [closed]

  22 mai 2024, par Lord Helmchen

  I developed a small application for my father. It uses Spring Boot, MySQL and FFMPEG, which I currently installed on Linux.

  


  I want to host it, deploy it automatically, have a back up and root access for FFMPEG installation.

  


  It runs smoothly locally on Windows / Linux, now I want to host it somewhere.

  


  What I would like to have :

  


  

  • Ease of deployment : I got experience in adminstration of linux root servers, but I look for something easy to integrate and maybe automatically deploy it from Github or Gitlab

  


  • Backup : I want to backup the database ideally to another service provider in case something goes wrong.

  


  • Linux : One Part of it, amongs others is to convert different audio formats using ffmpeg.
So, (I think) I need linux root access as well.

  


  • Time Horzion : I would like to make sure it still runs in ten+ years, so it should be a reliable provider where I only update the application from time to time if needed.

  


  • Money : As it is only for personal use at this moment, I don't want to invest a fortune.

  


  


  What provider and deployment pipeline would you recommend to me ?

  


• mpv player with SFTP does not work in bash script [closed]

  19 mars 2024, par Pickles888

  I am making a bash script to make it easier to stream from my media server at home.

  


  In the bash script, it asks whether you want to list or search, and then uses mpv to stream the file. For some reason it says the file does not exist. When I try this in the terminal it works, but running the script gives this error :

  


  [ffmpeg] libssh: Error opening sftp file: SFTP server: No such file
Failed to open sftp://[username:password]@[ip.of.server]/[directory/to/file]


  


  My script :

  


  #!/bin/bash

pass="[password]"

if [ $(nmcli | grep -c [home-network]) -gt 0 ]; then
    ip="[private.ip]"
else
    ip="[public.ip]"

  Anything put in brackets is to not share my personal info (except for arrays, if statements etc)

  


  Also this seems to have only changed while I was making the script. In the beginning, it was working great, but at one point it randomly stopped working.

  


  I have a feeling its some kind of quote mess up or something stupid like that. I have tried to edit it and fix it to the best of my abilities but nothing I did fixed it.

  


  I also think it could have to do with it being run in the bash environment as I normally use zsh. However I tested it in my shell by running /bin/bash and executing the command and it worked.

  


  Also the option chooser was not made by me.

  


• avformat/rtsp : extend the PATH buffer to 2048

  7 août 2024, par Stefano Mandelli

  avformat/rtsp : extend the PATH buffer to 2048
  Recently, I have been experiencing an increasing number of user that use ffmpeg
  
  to retrive RTSP stream from personal mediaproxies (e.g. MediaMtx) with
  
  authorization based on JWT. The current length of PATH does not permit to
  
  insert the token in the URL failing the authorization with no possibilities to
  
  get the video.
  VLC has just modified the RSTP max URL length, and it permits to use token
  
  inside the URL.
  For these reasons, I propose this patch to extend the PATH buffer from 1024 to
  
  2048 in order to use tokens and the authorization process based on JWT.
