x264 development: reference list reordering testing
http://mirror05.x264.nl/Dark/test_old.mkv
http://mirror05.x264.nl/Dark/test_new.mkv Before I commit a change I have locally, I'd like to make sure no decoders barf on it. In short, is there a decoder out there that plays one of these without problems, but not the other? libavcodec, JM, and Elecard Streameye have no issues. CMA1820 whines and whines but decodes it correctly anyways. Challenge: find one that does have issues. Bonus points: decode to raw YUV and diff against a correct decode (e.g. from ffmpeg).

I've encountered a strange problem so I think it's useful to report here. When playing back both "old" and "new" through DXVA (media player is "media player classic (latest rev.)", videocard is an ATI 5770 and drivers are Catalyst 10.3a) this is what I see:
As you can see, there are noticeable macroblocks on the rays, and few other macroblocks around in the picture. These macroblocks, during the playback, goes away for an instant when there is an I-frame, but then they come back. Maybe it's non-DXVA compliant? Or is it a DVXA-ATI bug?

Sounds like an ATI bug... |

MPC-HC r1788 x86 (EVR Custom, optimal renderer settings, internal matroska splitter)
- internal ffmpeg & DXVA work perfectly, no errors or dropped frames on both clips - CoreAVC 2.0 software & CUDA drop 1 frame in the very beginning and 1 more frame at second 9 with CUDA, same on both clips |

Both seem to work fine on (S)MPlayer git20100415 using VDPAU on nVidia driver 195.36.15 and a GeForce 8400GS (G98 chip).
I don't know how to check for dropped frames, though. Any tips? Last edited by creamyhorror; 20th April 2010 at 11:46. |

I could imagine that re-ordering the references in a way that a "usefull" ref-frame is kept longer in DPB while a "less usefull" one is dropped earlier, may be helpful in certain situations...
