• HLS Encoding Resulting in "No Supported Source Was Found"

  18 février 2023, par Paulamonopoly

  I'm currently facing the most bizare problems I've come across, so I'm hoping someone can explain why this is happening. I'm currently converting my Movie and Show libary to HLS for buffering and bandwidth reasons etc.

  


  My file structure for these movies and shows are as follows :

  


  /Movies/[TMDB ID]/[TMDB ID].mp4

  


  /Shows/[TMDB ID/[Season Number]/[Episode Number]/[Episode Number].mp4

  


  I have converted my entire movie collection successfully using the below command.

  


  find /* -type f -name "*.mp4" -exec realpath {} \; -exec ffmpeg -i {} -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls -hls_segment_filename '{}-P%03d' {}.m3u8 \;


  


  This is taking my named mp4 files and converting them to the originalname.m3u8 with chunks following the naming scheme of originalname-PXXX where P indicates the part number. I know there's no file extensions attached with the chunks but it's not needed.

  


  You can view this result here : Example

  


  This result also works if loaded into HLS Player : HLS Player

  


  So there is evidently nothing wrong with the converting of my videos or even the result of the videos.

  


  Now, if I convert a TV Show using the exact same command, it does indeed convert them, it does use a slightly different file structure as with seasons and episodes etc which can be seen above, but now it results in the error : "No Supported Source Was Found" in the console and repeatedly tries to play Part 000 without success.

  


  This can be seen here : Example

  


  And the errors if loaded into HLS Player : HLS Player

  


  I have tried changing numerous things to try and resolve this error as well as checking things, the things I have checked are the media condition itself maybe it's a corrupted file ?

  


  The original Mp4 file can be played here without any problems, so we know the Mp4 file originally is perfectly fine. I have also tried adding a file extension to the chunks such as .ts and .mp4 etc etc with also no success.

  


  I have even thought maybe it's the directories so I have moved a show into the movies directory with no success, I have also moved a movie into the show directory which resulted in a working HLS Stream so it's nothing to do with the directories.

  


  I have tried exending the file name length thinking it's possibly the naming scheme with 1.m3u8 not been long enough of a file name by using placeholder text such as 03051.m3u8 as well as the chunk naming scheme 03051-PXXX possibly not been long enough.

  


  I have noticed though that using this command :

  


  ffmpeg -allowed_extensions ALL -i {} -c copy -bsf:a aac_adtstoasc {}.mkv \;


  


  Does recombine my HLS video correctly with the same file size etc, however I have noticed that the video itself is corrupt and doesn't play. So this makes be believe the issue lies within the converting of the initial Mp4 file into m3u8.

  


• How to output series file name to folder name without seasons number

  7 mars 2023, par Mostafa Daash

  just i want to make out put like example using for f

  


  i have series episode
Fast Fast S01E02.mkv
i want output to directory /media/Fast Fast/Fast Fast S01E02.mkv

  


  how i can equivalent folder name from file name without S01E02

  


  i use this

  


  for f in *.mkv; do ffmpeg -i "$f" -i logo.png -filter_complex "overlay=40:main_h-overlay_h-40" -codec:a aac -c:v h264 /media/folder name/"${f%.*}".mkv

  


  for f in *.mkv; do ffmpeg -i "$f" -i logo.png -filter_complex "overlay=40:main_h-overlay_h-40" -codec:a aac -c:v h264 /media/folder name/"${f%.*}".mkv

  


• make fifo pipe in java(windows), write some data into it, let other process read the pipe

  9 novembre 2017, par vs93

  My objective is to create a named pipe(fifo) in windows(java), write some data(coming from camera) into that and invoke ffmpeg command to make mp4 from that data. But I suspect that it is not opening a fifo pipe, rather it is opening a file. How can I make it open a fifo pipe ?
  Here is the code :

  public void run () {
  
  String mp4Folder = "C://Users/user_2/Desktop/streamDestination";            // Where the MP4 is to be kept
  
  VFrame frame = null;
  
  int actualPipeValLen = 0;
  
  FileOutputStream requestStream = null;
  
  long lastProcessedTS = 0;
  
  final String FIFOPATH = "D://FIFO//";
  
  final String PIPE_NAME = FIFOPATH + "myfifo";
  
  final String MKFIFOCOMMAND = "mkfifo -m=rw " + PIPE_NAME;
  
  final String DELFIFOCOMMAND = "rm -r " + PIPE_NAME;
  
  String mp4FileName = mp4Folder + File.separator + "1.mp4";
  
  mp4FileName = mp4FileName.replace("\\", "/");
  
  long firstTimeStamp = 0;
  
  try {
  
      Runtime.getRuntime().exec(MKFIFOCOMMAND);
  
  } catch (IOException e1) {
  
      e1.printStackTrace();
  
  }
  
  if(firstTimeStamp == 0) {
  
      firstTimeStamp = frame.getTimestamp();
  
  }
  
  if((frame.getTimestamp() - firstTimeStamp) > (15 * 1000)) {
  
      if(requestStream != null) {
  
          requestStream.close();
  
          requestStream = null;
  
      }
  
      if(actualPipeValLen > 0) {
  
          String[] ffmpeg = new String[] {"ffmpeg", "-i", PIPE_NAME , "-vcodec", "copy", mp4FileName };
  
          Process ffmpegProcess = Runtime.getRuntime().exec(ffmpeg);
  
          actualPipeValLen = 0;
  
          firstTimeStamp = lastProcessedTS;
  
          Thread.sleep(2 * 1000);
  
          try {
  
              Runtime.getRuntime().exec(DELFIFOCOMMAND);
  
          } catch (IOException e1) {
  
              e1.printStackTrace();
  
          }
  
          System.exit(0);
  
      }
  
  } else {
  
      System.out.println("Writing into pipe : " + actualPipeValLen);
  
      if(requestStream == null) {
  
          requestStream = new  FileOutputStream(PIPE_NAME);
  
      }
  
      requestStream.write(frame.getFrame());
  
      actualPipeValLen += frame.getFrame().length;
  
      lastProcessedTS = frame.getTimestamp();
  
  }

  }
