• Events after FFmpeg in Cmd command is completed in C#

  30 juin 2017, par Манаф Иракский

  I am creating windows form application using C# to manage cmd arguments of FFMPEG, also, I am using FileWatcher, my application as long as its running after clicking the button "start watching" is will watch if any new file landed in the folder, its will open CMD.exe and the argument will use FFMPEG to convert this Video file. its working but the issue is my C# application sends the command to cmd and thats it but I want to handle other tasks like if FFMPEG completed the task delete the original file ? how I can determine in my app thats CMD command completed and then start next task. here is my cod

  namespace WindowsFormsApplication1
  
  public partial class Form1 : Form
  
  public Form1()
  
  InitializeComponent() ;
  

      private void button1_Click(object sender, EventArgs e)
  
      {
  
  
  
          FileSystemWatcher watcher = new System.IO.FileSystemWatcher();
  
          watcher.Path = @"MY PATH";
  
          watcher.NotifyFilter = NotifyFilters.LastWrite;
  
          watcher.Filter = "*.*";
  
          watcher.Changed += new FileSystemEventHandler(OnChanged);
  
          watcher.EnableRaisingEvents = true;
  
  
  
  
  
      }
  
  
  
      private void fileSystemWatcher1_Changed(object sender, System.IO.FileSystemEventArgs e)
  
      {
  
  
  
  
  
      }
  
      private void OnChanged(object source, FileSystemEventArgs e)
  
      {
  
  
  
           DirectoryInfo d = new DirectoryInfo(InPath .Text );
  
          FileInfo[] Files = d.GetFiles("*.*");
  
          string str = "";
  
          foreach (FileInfo file in Files)
  
          {
  
              str = str + file.Name;
  
          }
  
  
  
          var strout = Path.GetFileNameWithoutExtension(str);
  
          string strCmdText;
  
          strCmdText = @"/C ffmpeg.exe -i X.mp4 -Vcodec X Xout.mp4"; /// this is just argument example 
  
          System.Diagnostics.Process.Start("CMD.exe", strCmdText);
  
  
  
  
  
      }
  
  
  
  
  
  
  
      private void Form1_Load(object sender, EventArgs e)
  
      {

• Interplay MVE : Implement frame format 0x10

  25 juin 2017, par Hein-Pieter van Braam

  Interplay MVE : Implement frame format 0x10
  This implements the 0x10 frame format for Interplay MVE movies. The
  
  format is a variation on the 0x06 format with some changes. In addition
  
  to the decoding map there's also a skip map. This skip map is used to
  
  determine what 8x8 blocks can change in a particular frame.
  This format expects to be able to copy an 8x8 block from before the last
  
  time it was changed. This can be an arbitrary time in the past. In order
  
  to implement this this decoder allocates two additional AVFrames where
  
  actual decoding happens. At the end of a frame decoding changed blocks
  
  are copied to a finished frame based on the skip map.
  The skip map's encoding is a little convulted, I'll refer to the code
  
  for details.
  Values in the decoding map are the same as in format 0x06.

• ffmpeg - "Could not find the codec parameters" (Live Stream)

  8 mai 2017, par Gagandeep Singh

  I am trying to record a live HTTP stream using the following command :

  ffmpeg -analyzeduration 2147483647 -probesize 2147483647  -i "http://mumsite.cdnsrv.jio.com/jioplay.catchup.cdn.jio.com/recordings/H8_S480_H264_MP/2556/1493919000.mp4/init/LIVEPROGRAM_CHANNEL_2556_START_1493919000_END_1493922600?uid=guest_uid&recid=SCHEDULED-A00B00C00D00E00F-_-_-2556_48168092&shard=shard_a&sid=77179867662431494241905&i=2&nwk=WIFI&pk=1&CurrentNetworkType=WIFI&CurrentNetworkType=WIFI" -c copy -absf aac_adtstoasc testing.ts

  Below is a screenshot of the ff-prompt console :

  http://i64.tinypic.com/331d55w.jpg

  It looks like the URL is correct but no data is being saved in the file and these warning messages are shown :

  multiple fourcc not supported

  Could not find codec parameters for stream 1 (Video : none (encv /
  0x76636E65), none, 576x432) : unknown codec

  How do I determine which codec would handle that stream or is the reason something else ?
