There is a function called sws_setColorspaceDetails in swscale. That might be useful.

As far as I can see, it works only for 8-bit YCbCr to RGB conversion. |

Any pictures decoded after an IDR picture should be displayed even if the POC is earlier than the IDR picture. I don't know where the bug is, ffdshow or libavcodec. Not likely in ffdshow, but not sure... |

The point remains that a B-frame is bi-predictive, which means it needs two reference frames. avcodec itself will not decode a B-frame if it doesn't have two references yet, unless you set a special flag to blindly decode everything.

rgb16, i want you back
guys, scary story: i use 2002 via kle133 mobo with trident blade3d 8mb graphics on xp, can only handle 16bit color at 1280x1024. i output rgb from ffdshow to have control over conversion coefficients. after rev3765 even though theres no explicit rgb16 output option, ffdshow still connects normally in rgb16 to vmr7 (with rgb32/24-only checked in settings). but with directvobsub in between ffdshow and vmr7, it outputs rgb32/24, and following conversion rgb32/24->rgb16 in directvobsub produces unwatchable messed up picture. i didnt have much luck using ffdshow's own subtitler either on this computer.
so i need rgb16 option back or i'll be stuck with r3764 foreva -) |

Open directvobsub setitngs, and on the tab with list of preferred colorspaces, move rgb565 all the way up. Maybe that makes directvobsub to negotiate a 16bit connection. Too bad you can't remove colorspaces from the list, to make vsfilter not accept them... |

CODEC_FLAG2_SHOW_ALL, but it is only used in FFmpeg, not in Libav.

Hi.
Is there a way how to force FFDshow installer to deploy quicksync decoder even if my Intel HD Graphics 2000 GPU is disabled right now?

That has nothing to do with QS. PP is skipped when decoding H.264.

But why restricting it to any format and this isn't H.264 but Mpeg-2 and it doesn't work ?
Here it's working when forcing it externaly http://www.mediafire.com/?op1aegifswodc8p
