• Quick stream from file which exists

  4 mai 2017, par parsa

  I implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
  When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
  I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
  Here is my ffmpeg code for streaming :

  ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8 
  
                -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8 
  
                -s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8 
  
                -s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
  
                -s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8

  And here is the console output :

      ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil

  But I don’t have any problem for streaming files with creating resolutions from a file which have lower orginal quality than hd1080
  What I can to do ?

• How do I properly reduce the resolution of a 360 video using ffmpeg ?

  10 avril 2017, par user3799235

  I have tried reduction with the following technique from a scale of 2048:1024 with something like : ffmpeg -i eagle360half.mp4 -vf scale=1024:512 video360_1024.mp4 however the playback then becomes warped and warbly (visually similar to a bad vhs tape). I can only speculate that this has something to do with the meridians and equirectangular projections. How would I properly scale/ reduce resolution of a 360 video using ffmpeg, or is this possible with some other cli tool ?

  Here is the output of mediainfo, ffmpeg, and then mediainfo again :

• Reading a File while it is being written by FFMPEG

  29 mai 2014, par Haris Tasawar

  As the title suggests, i am in the process of creating a client/server application where the server(PHP) reads a file which is being written on by ffmpeg and then outputs it to the client(JAVA). I have succeeded in writing the server script in php which initiates the ffmpeg and then after a while starts to read the file and concurrently sends it to the JAVA client, the problem is that after a while the client stops to receive any sort of data and then just quits, For example if i have a 5MB file, it would read only 12KB and then it quits. Could someone tell what can be the issue here ? Is it on the server side or on the client side.
  For References i am attaching both the reading of file code in php and the client side code.

  Code For Reading the file while FFMPEG converts the file(PHP) :

  $file = 'D:\\'.$destination;
  
  $fp = @fopen($file, 'r');
  
  //ob_end_clean();  
  
  header('Content-Description: File Transfer');
  
  header('Content-Type: application/octet-stream'); 
  
  header("Cache-control: private");
  
  header('Pragma: private');
  
  header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
  
  header('Content-Length: ' . filesize($file));
  
  
  
  $buffer = 4096;
  
  while(!feof($fp)) {
  
  
  
  usleep(300000);
  
  echo fread($fp, $buffer);
  
  ob_flush();
  
  flush();
  
  
  
  
  
  }
  
  fclose($fp);
  
  exit();

  Code For reading the File transferred by PHP (JAVA) :

  URL u = new URL(streamURL);
  
  
  
                  clientSocket = (HttpURLConnection) u.openConnection();
  
  
  
                  if( clientSocket.getResponseCode() == HttpURLConnection.HTTP_OK ){
  
                  //clientSocket.setReadTimeout(0);
  
                  inRemoteStream = clientSocket.getInputStream();
  
  
  
  
  
                  while (((count = inRemoteStream.read(buf)) != -1)) {
  
                      offset += count;
  
                      System.out.println(offset);
  
                      fileOutputStream.write(buf, 0, count);
  
                      setVideoOffset(offset, contentLength);
  
                  }

  I`ll be very happy if someone can solve this problem for me :) .
