• Save video from rtsp and play in exoplayer simultaneously [closed]

  25 janvier 2024, par Julian Peña Gallego

  I am trying to receive a live stream via RTSP from an IP camera in Android Kotlin, I am recording the video to a local file with ffmpegkit but I must additionally view the live stream.

  


  When I record the live stream with ffmpeg without playing the stream through exoplayer it works fine, but when both processes are running there is packet loss in the video recording or in the exoplayer.

  


  Then I tried to get exoplayer to play the video that ffmpeg was recording, but it gave me an error since the file has not been closed yet.

  


  Could you provide me with a solution ? I have found on the internet that it is possible with server sockets but they do not indicate how to do it.

  


• FFMPEG - Invalid and inefficient vfw-avi packed B frames detected -> ffmpeg doesn't stop at given endpoint

  14 avril 2014, par user2198746

  I am quite new to ffmpeg and video converting in general. I use ffmpeg to extract the first 30 seconds of a movie and convert it to mov. Everything worked fine until one of my video files caused ffmpeg to warn me with this message :

  Invalid and inefficient vfw-avi packed B frames detected

  Then the converting starts, but doesn't stop after the the 30 seconds mark is reached.

  frame= 1949 fps= 22 q=28.0 size=    4284kB time=30.01 bitrate=1169.2kbits/s 

  The frame count is still increasing, the time stays at 30.01 ...

  Here's the ffmpeg command i am using

  ffmpeg -y -i input.avi -ss 00:00:00.0 -t 00:00:30.0 -vf scale="1024:trunc(ow/a/2)*2" -acodec copy output.mov

• Non stop stream to rtmp with FFMPEG

  13 février 2020, par Надежда Перемен

  I want to stream to RTMP with FFMPEG. I need to dynamically change next play file, for that i use web urls for my localhost.

  I have PHP file located : http://127.0.0.1/mp3.php

  $file = '1.mp3';
  
  
  
  $mime_type = "audio/mpeg, audio/x-mpeg, audio/x-mpeg-3, audio/mpeg3";
  
  
  
  if(file_exists($file)){
  
      header('Content-type: {$mime_type}');
  
      header('Content-length: ' . filesize($file));
  
      header('Content-Disposition: filename="' . $file);
  
      header('X-Pad: avoid browser bug');
  
      header('Cache-Control: no-cache');
  
      readfile($file);
  
  }else{
  
      header("HTTP/1.0 404 Not Found");
  
  }

  And i run ffmpeg with this command line :

  ffmpeg -re -stream_loop -1 -i logo.png -stream_loop -1 -i http://127.0.0.1/mp3.php -ab 320k -c:v libx264 -f flv "rtmp://ms......."

  This works, but it playing only once time and FFMPEG returns an error :

  Seek to start failed
http://127.0.0.1/mp3.php: Function not implemented

  How can i fix it ?
