Strangely, code compiled on my home system didn't compile in other systems. A function refused to inline causing a warning that turned into an error.
Fixed at 4222. No ffdshow code change.

Yes, look here:
http://forum.doom9.org/showthread.php?t=163110 I also ran the 10 clips on my own PC (i7-2600) with a newer version of ffdhsow-quicksync: http://forum.doom9.org/showthread.ph...92#post1548192

AMD CPU (without SSE2): QuickSync DLL: not found (ffdshow -> About page -> Version details) Intel CPU (without Intel GPU): QuickSync DLL: Version properly shown (ffdshow -> About page -> Version details) Why is the DLL not "found" on AMD system? I know it doesn't work on AMD but the DLL itself should be listed under About page -> Version details! Last edited by Dstruct; 4th January 2012 at 11:48. |

Is there any way for ffdshow to honor the full range flag in H.264 videos if it's specifically set? I encoded a few videos and specifically set the full range flag but regardless of whether I choose Auto or Standard for the output range, it's still outputting limited range. I'm hoping there's an alternative to selecting Full Range each time those videos are played.
The more I think about it, the more certain I am that the tooltip for Auto is unclear whether the H.264 full range flag is honored or not. |

I have a FFDshow feature request
Can ffdshow render subtitles to a secondary pin ? Like this If it acted as a pass through filter for the video we could support DXVA this way, which is a big plus. The secondary pin can just output RGBA no need to worry about all the hundreds of different colour spaces. Can be more efficient too since only need to update the subtitle image when the text needs to change, rather than composite it every frame. |

I can't see it being a huge amount of work, although I've not really studied the FFDShow source.
I might be able to assist. I am actually a c++ programmer. Specialise in opengl, but I know directshow. Written an opengl renderer in dshow ;p Im guessing you would need a new pin type for pass through, since it would be reading the sample type, for video size but not altering it. |

Subtitles rendering is not pass through nor just alpha blending bitmaps. The input pin accepts text or coded bitmap and rasterize/decode them. And finally blend to the video. The output stage may be issued to a video renderer. It is not easy. None the less, you can do it . I hope you have patience huge enough to deal with the messy existing code. |
