• 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 ?

  


• How to use Jaffree with Spring Boot for streaming a RTSP flow

  25 août 2022, par Jmarchi

  Im trying to build a APIRest and one of the things i want to do is recirculate the rtsp video provided by some security cameras to the frontend.

  


  I have found the Jaffree, a dependency that integrates the ffmpeg into spring, until then all is good.

  


  The problem is when i try to send the video to the frontend (make in React) i recieve this error :

  


  


  Starting process : ffmpeg

  [warning] Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (tcp ://127.0.0.1:52225) has not been used for any stream.

  The code in the backend is this :

  And this is the html part :

  


  <video width="100%" height="auto" controls="controls" autoplay="autoplay" muted="muted" src="http://localhost:7500/***/1/video">&#xA;                Sorry, your browser doesn&#x27;t support embedded videos.&#xA;            </video>&#xA;

  


  What is it missing for the TCP negotiation ?

  


• Joining/Concatenating more than one video files in Java Spring Boot

  7 décembre 2020, par Rohan Shah

  I am trying to join/concate multiple files in Java, so far the procedure that I was following (https://github.com/bramp/ffmpeg-cli-wrapper) was going alright, but in this procedure, there were a couple of lines that I could not understand.

  


  Code I am following :

  


  FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");

FFmpegBuilder builder = new FFmpegBuilder()

  .setInput("input.mp4")     // Filename, or a FFmpegProbeResult
  .addInput("input2.mp4")    // <--------------------------------  Second file that I added
  .overrideOutputFiles(true) // Override the output if it exists

  .addOutput("output.mp4")   // Filename for the destination
    .setFormat("mp4")        // Format is inferred from filename, or can be set
    .setTargetSize(250_000)  // Aim for a 250KB file

    .disableSubtitle()       // No subtiles

    .setAudioChannels(1)         // Mono audio
    .setAudioCodec("aac")        // using the aac codec
    .setAudioSampleRate(48_000)  // at 48KHz
    .setAudioBitRate(32768)      // at 32 kbit/s

    .setVideoCodec("libx264")     // Video using x264
    .setVideoFrameRate(24, 1)     // at 24 frames per second
    .setVideoResolution(640, 480) // at 640x480 resolution

    .setStrict(FFmpegBuilder.Strict.EXPERIMENTAL) // Allow FFmpeg to use experimental specs
    .done();

FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);

// Run a one-pass encode
executor.createJob(builder).run();

// Or run a two-pass encode (which is better quality at the cost of being slower)
executor.createTwoPassJob(builder).run();


  


  These are the lines throwing error :

  


  FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");


  


  In these lines, I am providing a path like this,

  


  FFmpeg ffmpeg = new FFmpeg("D:/");
FFprobe ffprobe = new FFprobe("D:/");


  


  which leads to an error

  


  java.io.IOException: CreateProcess error=5


  


  I believe the ffmpeg in /path/to/ffmpeg and ffprobe in /path/to/ffprobe are files, not directories, which is why it threw an execution permission error, but as I looked into the repository (link given above) I was not able to find this particular file in the given link.

  


  There were a couple of Java files named ffmpeg.java and ffprobe.java, but when I tried using them in the code then I got the same error, so I want to know which files am I supposed to have in these paths
