• Deprecate avctx.coded_frame

  15 juillet 2015, par Vittorio Giovara

  Deprecate avctx.coded_frame
  The rationale is that coded_frame was only used to communicate key_frame,
  
  pict_type and quality to the caller, as well as a few other random fields,
  
  in a non predictable, let alone consistent way.
  There was agreement that there was no use case for coded_frame, as it is
  
  a full-sized AVFrame container used for just 2-3 int-sized properties,
  
  which shouldn’t even belong into the AVCodecContext in the first place.
  The appropriate AVPacket flag can be used instead of key_frame, while
  
  quality is exported with the new AVPacketSideData quality factor.
  
  There is no replacement for the other fields as they were unreliable,
  
  mishandled or just not used at all.

• Reliably get PTS values in ffmpeg ?

  21 novembre 2013, par karl_

  I'm trying to write a method that will provide the next frame and presentation time stamp when queried. The code currently looks something like this :

  while( getNextFrame(image, pts) )
  
  {
  
      // show current image
  
      drawImage(currentImage);
  
      sleep(pts);
  
      currentImage = image;
  
  }

  I've been following the Dranger tutorials to this point, but have stalled on reliably getting a PTS value for frames (http://www.dranger.com/ffmpeg/tutorial05.html). The PTS values returned are always 0.

  Also, get_buffer() has been deprecated, so I'm now using the get_buffer2() method to set the global pts value. However, the release_buffer method has also been deprecated and I can't seem to find it's replacement. This leads me to believe that the method laid out in the tutorials may no longer be the best way of accomplishing this task.

  In short, using up to date ffmpeg, what's the best way to grab frame pts values reliably ?
