• Redirect StandardOutput from a process

  25 décembre 2015, par Prakash M

  I am working on C++/CLI winforms
  how to redirect standard output to textbox ?
  I followed this video, but it didn’t work
  https://www.youtube.com/watch?v=BDTCviA-5M8

  I can see output in console window, but till process finishes GUI freezes !

  ProcessStartInfo ^psi = gcnew ProcessStartInfo("D://ffmpeg.exe", "-y -i D://1.avi D://process.mp4");        
  
  psi->WindowStyle = ProcessWindowStyle::Hidden;
  
  psi->UseShellExecute = false;
  
  psi->RedirectStandardOutput = true;
  
  process->StartInfo = psi;
  
  
  
  process->Start();
  
  String^ details = process->StandardOutput->ReadToEnd();
  
  textBox1->Text = details; 
  
  Console::WriteLine(details); 

  Where am I going wrong ?

• Which command line and version do I need to reproduce those properties ?

  26 décembre 2015, par Zurechtweiser

  I have a file for which ffmpeg gave those properties :

  ...
  
  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'TEST.MOV':
  
    Metadata:
  
      major_brand     : qt  
  
      minor_version   : 0
  
      compatible_brands: qt  
  
      creation_time   : 2015-12-26 07:45:26
  
    Duration: 00:00:02.75, start: 0.000000, bitrate: 4935 kb/s
  
      Stream #0:0(eng): Video: h264 (Main) (avc1 / 0x31637661), yuvj420p(pc), 1280x720 [SAR 1:1 DAR 16:9], 4775 kb/s, 59.94 fps, 59.94 tbr, 180k tbn, 119.88 tbc (default)
  
      Metadata:
  
        creation_time   : 2015-12-26 07:45:26
  
        handler_name    : Ambarella AVC
  
      Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 48000 Hz, mono, fltp, 64 kb/s (default)
  
      Metadata:
  
        creation_time   : 2015-12-26 07:45:26
  
        handler_name    : Ambarella AAC

  Which command line and version do I need to reproduce those properties ?

  I tried

  ffmpeg -i "test.mp4" -s 1280x720 -vcodec libx264 -c:a libvo_aacenc -q:a 3 -r 59.94 -b:v 4935k -b:a 64k -ac 1 -ar 48000 TEST2.MOV

  But it’s not the same.

  Goal is simple : my actioncam has a hdmi-output. I want to watch movies next to my own footage using my actioncam when I am abroad. Goal is to make the actioncam think, it was it’s own footage to play it back. Currently I only get ’invalid’.
