Poor quality after forcing a golden frame that only refer to an old altref frame #227

Closed GoogleCodeExporter closed 9 years ago

What is the expected behavior? What do you see instead?
Expected no visible degradation of video quality, now I see pixelation  

What version are you using? On what operating system?
Using 0.9.5 Windows7

Can you reproduce using the ivfdec or ivfenc tools? What command line are
you using?
No

Please provide any additional information below.
I'm setting the following flags when calling 
vpx_codec_encode(_encoder, _raw, _timeStamp, VP8_FRAME_DUR, flags, 
VPX_DL_REALTIME)

  flags |= VP8_EFLAG_NO_REF_LAST; // Don't reference the last frame
  flags |= VP8_EFLAG_FORCE_GF;    // Force a golden
  flags |= VP8_EFLAG_NO_UPD_ARF;  // Don't update altref 
  flags |= VP8_EFLAG_NO_REF_GF;   // Don't reference the golden frame

my last altref frame is 30 frames back (old) even without movement from that 
time there is still a clear quality degradation
