View Full Version : Smart Tee & VirtualVCR & MJPEG Lossless

I am using the following:
-VirtualVCR
-Huffyuv codec (works)
-PICVideo JPEG Lossless codec (does not work)
-nVidia VIVO (GeForce 7800GT)
-my own SVHS VCR (for cable tuning)

I can record fine with no dropped frames with Huffyuv (32.4GB/hour, including WAV 48KHz audio). However, if I use most any other codec, including PICVideo's JPEG Lossless, I get this error:
"Could not render filter
Smart Tee -> Compression Codec -> Flow meter"

Using the Smart Tee filter is the only way I can preview. If I disable Smart Tee for encoding, it still gives the same error messsage. I have all the filters that come with VirtualVCR regsvr'd and still receive the error with PICVideo. I really just want to save some space.

Help is gladly appreciated. I have done some searching however nothing pops up for "flow meter." I understand most of you guys seem to be using VDub but that's just too slow on my system (although I have a Athlon 64 3500+). I guess I have yet to try the VfWWDM thing.

@Tatsh

¿Are your capturing in RGB mode and JPEG expect YUY2 (or viceversa)?

My only option in any app with this card seems to be UYVY. I can't force RGB or anything else (gets error message).

ok i tried what your doing. i set Vvcr color format to yuy2 and tried picvideo jpeg and got the same error. i enabled the compress rgb thing in pcivideo options and still gotthe same error. then i tried rgb24 and it woked. defia.ntly its the color format. try changin it to rgb24 in Vvcr.

edit
well seems likr you tried this.

edit2.
i just tried some compression using hufyuv/picvideo lossless jpeg and huffyux gave 20000 Kbps less than the loessless jpeg (35542 and 59174) this is for 384x288 res. your better of using huffyuv really.

You can always run it through the ffdshow video processor or similar if you want to change colourspace...

I had the same problem, 7900gt instead. See if you have more than one MJPEG choices. I picked "MJPEG Compressor" at first and received the error. Then I noticed "PICVideo 3 DirectShow M-JPEG Compressor" and "PICVideo M-JPEG 3 DirectShow Compressor". Either these works for me. Good luck.
