• FFMPEG "Could not allocate memory" Errors through php

  10 décembre 2019, par Applepiee

  I’ve tried to find a solution online for days now but cannot find any solution.

  I just switched server (Intel Xeon to AMD) and since the switch I’ve not been able to get ffmpeg conversions working through the php script. ffmpeg was the exact same version and all php settings are set.

  All commands that the script executes (copied from log files) were tried in shell and executed with no problems.

  The errors look like this :

• How to fix "Non-monotonous DTS in output stream 0:1" when trying to convert a m3u8 file into a mp4 using ffmpeg

  23 mars 2019, par Alessandro Autiero

  I’m currently coding a desktop util that downloads Twich Clips if they meet some requirements. As the twitch api gives as a response a m3u8 file, I have to convert it into a mp4. To do with I’m executing a cmd command through my Java application using the ProcessBuilder API built into Java. The command works fine, but sometimes I get a buggy video that has broken frames and audio. Here’s my code :

  public static void convertFile(File input, File output) {
  
      String command = "ffmpeg -protocol_whitelist file,http,https,tcp,tls,crypto -vsync 2 -i \"" + input.getAbsolutePath() + "\" -c copy " + "\"" + output.getAbsolutePath() + "\"";
  
      System.out.println("______________________________________________________");
  
      System.out.println("Converting file...");
  
      System.out.println("Using as input " + input.getAbsolutePath());
  
      System.out.println("Using as output " + output.getAbsolutePath());
  
      System.out.println("Using as command: " + command);
  
      System.out.println("______________________________________________________");
  
      setHasDone(false);
  
  
  
      ProcessBuilder pb = new ProcessBuilder();
  
      pb.command(command.split(" "));
  
  
  
      pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
  
      pb.redirectError(ProcessBuilder.Redirect.INHERIT);
  
  
  
      Process process;
  
      try {
  
          process = pb.start();
  
      }catch (IOException e){
  
          e.printStackTrace();
  
          return;
  
      }
  
  
  
      while (process.isAlive()){
  
          setHasDone(false);
  
      }
  
  
  
      setHasDone(true);
  
  }

  Example of broken video :
  https://youtu.be/FfFvStNl-9o

  When uploaded to youtube lot’s of the video bugs are not present, not really know why, but at the end you can clearly see what I’m talking about. Am I using ffmepg wrong ?

  I posted this as none of the 1000 answers on similar posts helped me.

• ffmpeg issues "501 Not Implemented" while recording an RTSP stream

  28 février 2019, par atsushi

  I have a 4K camera (Sony SNC-VB770) streaming RTSP.

  I’m trying to record the stream into files (each has handy length, say, 1hour)
  using a simple script to repeatedly launch ffmpeg (ver 4.1) :

  while : ; do
  
    # (set $url and $outfile, and then)
  
    ffmpeg -rtsp_transport tcp -t 3600 -y -i $url -c copy -map 0:0 -b:v 16000k $outfile
  
  done

  If I run the script on a local PC directly connected to the camera, it works (longer than a week, at least).
  However, if I do the same on a server machine located in a data center, it fails randomly with no error message.
  Sometimes it runs for a few days, sometimes it dies in one minutes.

  Typical output looks like the following :

  # devname: snc-vb770
  
  # url: rtsp://10.40.35.90/media/video1
  
  # vb: 16000k
  
  # datefmt %d%H
  
  # addtimestamp 0
  
  no timestamp

  I’ve looked into RTSP packet and found an "RTSP/1.0 501 Not Implemented" is sent from ffmpeg to the camera.
  After that the camera eventually sent back "RTSP/1.0 505 RTSP Version not supported" and then ffmpeg quits shortly.

  The "501" packet seems to be generated by libavformat/rtsp.c:ff_rtsp_read_reply(),
  when ffmpeg receive a malformed RTSP packet with method=(null), status_code=0.
  I don’t know why such packets arrive at random timing and who is wrong (maybe the camera, maybe any of network switches or routers in the middle of the network path from the camera to the server machine).
  But anyway, I don’t want the recording to be stopped
  due to those malformed packets.

  Is there any workaround to make ffmpeg ignore invalid RTSP packets and just continue the recording ?

  Additional information :

  • I’ve tested the recording with both ffmpeg ver4.1 and 2.8.4 and no difference observed.

  • No difference observed at lower resolution nor at lower bitrate.

  • I have 3 cameras from various manufacturers in the same network environment.
    All of the three are working without problem for more than a month.
    Only the Sony SNC-VB770 shows the strange behavior.
