• PHP ffmpeg output location

  18 janvier 2016, par Mick Jack

  My website allow users to upload video files to the server. Original file will be move to folder "Original" ffmpeg will compress the video and store the video in 480p folder. how to i setup ffmpeg so that it will store output of the compressed video file into original/480p ?

  Partial code of upload.php

  $target_dir = "Original/"; //where you want to upload the files to
  
  $target_file = $target_dir.basename($_FILES['file']['name']);
  
  $fileType = pathinfo($target_file, PATHINFO_EXTENSION);
  
  $newFileName = $target_dir.sha1(pathinfo(basename($_FILES['file']['name']), PATHINFO_FILENAME)).'480p'.'.'.$fileType;
  
  //$newFileName = $target_dir.sha1(pathinfo(basename($_FILES['file']['name']), PATHINFO_FILENAME)).'-'.time().'.'.$fileType;
  
  move_uploaded_file($_FILES['file']['tmp_name'], $newFileName);

  using this FFMPEG command

  shell_exec("C:\\ffmpeg\\bin\\ffmpeg.exe -y -i ".$newFileName." -c:v libx264 -s:v 854x480 -c:a copy \"480p\\{$newFileName}\" > logfile.txt 2>&1");

  i get the error
  480p\Original/ffbaf58f1231628f9ac2a583f038b51719006ec6480p.mp4 : No such file or directory

  i will like the output to be stored in original/480p/compressed-video-file

• FFmpeg NaCl module avformat_open_input (on rtsp stream) returns -5 : I/O error

  8 janvier 2016, par Taimoor Alam

  I want to create an RTSP player in Chrome PNaCl.

  I have successfully built the ffmpeg naclport including the following networking flags in the build.sh file for the ffmpeg NaCl port.

  —enable network —enable-protocols —enable-demuxer=rtsp —enable-demux=rtp —enable-demuxer=sdp —enable-decoder=h264

  Furthermore, I have successfully coded and the linked the ffmpeg NaCl port in my own PNaCl module. I have included the following network permissions in the manifest.json file :

  "permissions": [
  
  {
  
      "socket": [
  
          "tcp-listen:*:*", 
  
          "tcp-connect:*:*", 
  
          "resolve-host:*:*", 
  
          "udp-bind:*:*", 
  
          "udp-send-to:*:*"
  
      ],
  
  }

  Now once I run the following code, in PNaCl, the avformat_open_input(...) returns -5 or I/O Error :

      AVFormatContext* formatContext = avformat_alloc_context();
  
  
  
      av_register_all();
  
  
  
      avformat_network_init();
  
  
  
      const char * stream_path = "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov";
  
  
  
      int result = avformat_open_input(&formatContext, stream_path ,NULL,NULL);
  
  
  
      if(result< 0){
  
  
  
          PostMessage("input not opened, result: ");
  
  
  
          PostMessage(result);
  
  
  
      }else{
  
  
  
        PostMessage(std::string("input successfully opened"));
  
  
  
      }

  What am I possibly doing wrong, and why can’t the PNaCl module access the RTSP stream ?

  PS. This is a similar question, but it gives no definitive answer.
