• How to dump RTSP to raw data file without encoding

  28 juin 2020, par Yves

  I've read this link : How to dump raw RTSP stream to file ?

  


  In this link, it seems that dumping RTSP stream to some formatted file, such as mp4, is normal.

  


  But I want to store the RTSP stream into the raw data files, instead of files like mp4, avi etc. And I should be able to extract data from the raw data files and send it out as RTSP stream too.

  


  In a word, this is what I need :

  


  

  1. receiving RTSP stream ---> 2. store RTSP data into raw data files ---> 3. read raw data files and send data as RTSP stream

  


  


  Why do I need this ?

  


  Because as my understanding, storing RTSP strema into some formatted file, such as mp4, needs to do an action of encoding (encode RTSP to mp4). But for me, I don't need this action, I simply need to store RTSP data and re-send it as RTSP stream. So if I can store RTSP into the raw-data file, instead of mp4, I don't need to spend computer resources on the action of encoding.

  


• bash : find truncates some paths [duplicate]

  17 novembre 2023, par fweber

  I'm using MacOS 13.0.1 and try to find + loop over .mov files to convert them to MP4 using FFMPEG. Many of my path contain spaces and special characters. I found a way of putting things together thanks to this post :

  


  function convert_to_mp4_then_rm() {
    while IFS= read -r -d '' file
    do
        ffmpeg -i "$file" "${file%.mov}.mp4"
    done < <(find /Users/f.weber/Downloads -type f -name "*.mov" -print0)
}


  


  This runs but I found a (random ?) error : it looks like some of the paths are truncated when they arrive to the ffmpeg CLI.

  


  Example to reproduce with a basic content :

  


  ll Downloads/
total 9472
-rw-r--r--  1 f.weber  staff   2,3M 26 sep 08:56 23-09-26 08-56-50-2538.mov
-rw-r--r--  1 f.weber  staff   2,3M 26 sep 08:56 23-09-26 08-56-50-2539.mov


  


  When I call convert_to_mp4_then_rm in a terminal, the first MOV file is properly processed then I have the following error from FFMPEG : /Downloads/23-09-26 08-56-50-2539.mov: No such file or directory. In some conditions (e.g. when the path is longer) the truncation is more obvious and can occur in the middle of a word.

  


  What is the explanation for this ? How to forward untruncated paths to my function's core ?

  


  Thanks !

  


• Recording video report for protractor execution on a remote environment

  23 septembre 2019, par Debasish Mukherjee

  I am executing my protractor test suite from my desktop and I am using a remote selenium server. I have configured the ’protractor-video-reporter’ to capture execution for my local windows environment (using ffmpeg codec) and when I execute using my local selenium server, the video capture works fine. But when I execute on remote VMs, it captures my desktop screen.
  I understand that I need to provide the remote location path to ffmpeg codec, but I do not know how to provide appropriate user credentials so that my automation can invoke the remote plugin ?
  My present configuration is as follows :

  const VideoReporter = require('protractor-video-reporter');
  
  ...
  
  let config = {
  
  ...
  
   onPrepare: () => {
  
   ...
  
   VideoReporter.prototype.jasmineStarted = function () {
  
                          var self = this;
  
                          if (self.options.singleVideo) {
  
                                  var videoPath = path.join(self.options.baseDirectory, 'protractor-specs.mpg');
  
                                  self._startScreencast(videoPath);
  
                                  if (self.options.createSubtitles) {
  
                                          self._subtitles = [];
  
                                          self._jasmineStartTime = new Date();
  
                                  }
  
                          }
  
          };
  
   ...
  
   jasmine.getEnv().addReporter(new VideoReporter({
  
          baseDirectory: './test-output/videoreport',
  
          createSubtitles: false,
  
          saveSuccessVideos: true,
  
          singleVideo: true,
  
          ffmpegCmd: "C:/FFmpeg/bin/ffmpeg.exe", /*Probably some changes needed here*/
  
          ffmpegArgs: [
  
                                  '-f', 'gdigrab',
  
                                  '-framerate', '30',
  
                                  '-video_size', 'wsxga',
  
                                  '-i', 'desktop',
  
                                  '-q:v', '10',
  
          ]
  
  }));
  
   ...
  
    }
  
    ...
  
  }
  
  export { config };

  Considering that execution and video capture both has to happen in remote server, please suggest a suitable solution.
