Correct color: Letterbox 16:9 unchecked and default output colorspaces settings checked. FFdshow output says YUY2
Bad color (too yellow): Letterbox 16:9 checked and default output colorspaces settings checked. FFdshow output says YUY2 Bad color (too yellow): Letterbox 16:9 checked and all output colorspaces unchecked except 'RGB32' and 'High YV12 to RGB conversion'. FFdshow output says RGB32 Bad color (too yellow): Letterbox 16:9 unchecked and all output colorspaces unchecked except 'RGB32' and 'High YV12 to RGB conversion'. FFdshow output says RGB32 Changing 'YCbCr' specification to 'ITU-R BT.709' also didn't help to get correct color with the last 3. I'm using ffdshow 3533 and the Latest ATI Catalyst 10.7 with default settings. I had installed a previous of Catalyst before. I uninstalled it completely, then installed the newest one made sure all settings were set to default (I only unchecked the noise filtering). Last edited by Alexander01; 21st August 2010 at 18:58. |

Hey,
while developing my new media splitter, i noticed that the ffdshow subtitle renderer doesn't properly deal with subs that are UTF-8 encoded. I have a sample here thats a UTF-8 encoded ASS sub, and it shows broken characters for the unicode chars. It works fine with DirectVobSub. I can provide the sample if required, but any non-english subs should eventually show the problem. How does ffdshow expect the character data? I realize it works with other splitters, so i'm mostly wondering if you could fix that more easily then i can. Any feedback on how to resolve this issue would be appreciated. Thanks! |

I also sent you a pm with the sample, but yeah, thats the one.
Using LAVFSplitter i get corrupted glyphs in the first sub (Sub für Jap-dub [ger]). It works with DirectVobSub, but it also works with other splitters and ffdshow. So i guess it could be fixed on either end. I would just need some insight on how to fix it, as i don't really have the time to dive into the ffdshow or directvobsub code. |

Build: http://www.mediafire.com/?41clo6a849c3bld BTW I've found something that may help you with the SSA fonts issue. Go to "SetMediaType" in TtextInputPin.cpp, line 78. What's this "extradata" stuff about? Setting it to 601 or 709 will just force one or another, your problem is that without lettebox it's using 601, and with letterbox 709 because of the new resolution. Either way I can't fix it since I can't reproduce it |

Hi,
I have a bug to report: When calling QueryInterface for "IID_IAMStreamSelect" on FFDShow's video decoder, subsequent calls to "IStreamSelect.Count(DWord variable)" raises an "EStackOverflow" exception. Tested with subtitles and without, makes no difference. Tested with 32bit clsid build #3529 |

Thanks Tom, in this sample CCs can be turned on and off with the CCs option in the subs section. People reported that CCs were always shown regardless of the option, so I thought it happened on all sources. Any CC samples that have this bug?

The CC option itself works ok as far as I can remember. The problem/confusion was that it functions independently from the state of the global subtitle filter option.

Hi all,
I am back from holidays I have just added support for cook audio decoding, let me know if there are issues. The decoder might not be as good as the one used by MPC : FFDshow uses ffmpeg, MPC uses Real's dlls Quote:
For now I can't see how we would fall on an overflow |

Great work Albain!
I have noticed one problem. The audio is messed up after seeking in a RealMedia video. It sounds like the audio samples are decoded in the wrong order. Without performing a seek the audio plays fine.
