When encoding an RGB source in VDub using ffdshow's HuffYUV and YV12 colorspace, how does ffdshow perform the colorspace conversion? Is it similar to ConverttoYV12 (using the same matrix, Rec601) in Avisynth?

Hi.
There seems to be a problem with FFDshow DXVA decoder when removing from graph - it will cause Graphstudio (and other software) to crash. It is easy to reproduce - just open any DXVA compatible video in graphstudio then try to remove FFDShow DXVA decoder from graph - Graphstudio will crash. This doesn't happend with normal FFDshow video decoder (and other DXVA decoders like PDVD).

I am unable to reproduce. I can delete the filter without problems in GraphStudio. Which renderer are you using? Here it ffdshow DXVA only works if manually inserted in combination with EVR.

I changed default renderer on my OS, so Graphstudio use EVR by default on my Win7.

Do you have a sample? I only have one mjpeg in avi file and that gives correct colors in VirtualDub.
It is easy to adjust colorspace in VirtualDub. Video -> Color Depth.

Hi Gurus
Quick question: I'm having trouble with my PGS subtitles. They always appear in the *upper left* corner of my screen. I've tried playing with the subtitles settings in ffdshow, and I'm able to change font size etc...but the placement won't change. Have I completely overlooked something basic here...? I'm running the latest version of ffdshow of course. Thanks |

Greetings, just a quick question. Is ffdshow supposed to be able to decode all wmv content without any problems? Cuz I have many .wmv vids (mostly WMV3/9) for which I only get a grey screen when selecting libavcodec for WMV3/9 and a green screen when I select wmv9 (the vids play fine if I use the internal windows wmv decoder). It doesn't matter which renderer I use, the resulting blocky green & grey screens still occur making the vid unwatchable. This has been going on for as long as I have been using ffdshow (7+ years) and even the most recent builds within the past week still have the same problem. Was just wondering if there is something I can do to finally fix this problem...
Thanks for any tips/guidance... |

This is how it can be reproduced (Vista/Win7): Start Graphstudio, look for EVR renderer, then change merit to max. Restart PC Open any DXVA compatible video in graphstudio, graph will be now builded using FFDshow DXVA decoder + EVR renderer (instead of video renderer). Try to remove FFDshow DXVA decoder from graph (click on ffdshow dxva decoder and hit delete key). Graphstudio will crash.

Try the internal subtitle renderer of MPC instead.

Please ignore the apparent "anomaly" in the MJPEG decoder --- it "magically" disappeared after I (re-)installed ReClock Yep, the rootkits are getting more and more evil, their "residual symptoms" are completely "absurd", but they do exist and happen anyway.

@zummi
DirectVobSub has the same capapbilities as the internal subtitle renderer of MPC. @andybkma This is a splitter problem. It does not work properly with the standard MS splitter. The files play properly when forcing LAV Splitter as the source filter. Here is a Registry tweak for that: Code:
Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\Media Type\Extensions\.wmv] "Source Filter"="{B98D13E7-55DB-4385-A33D-09FD1BA26338}"

You are the first to mention such problems.
What exactly do you mean with lag? A sync delay? Stuttering? Does the problem go away if you adjust the number of decoding threads in the decoder options? Does it only happen with M2TS? MKV and MP4 are fine?
