Windows 7 + VC-1
Windows 7 supports decoding of various formats out of the box. H.264 playback is there and it decodes fine through DirectShow. VC-1 playback is there, but when AviSynth tells it to decode through DirectShow it does not work.
I can use libavcodec for VC-1 decoding (with a little fiddling around), but playback shows artifacts when jumping and so does the compression tests I make. http://i25.tinypic.com/21188so.jpg I would guess it does not make for a good compression test then. Is there any way to get Microsoft's decoder to work through DirectShow or get rid of the libavcodec artifacts? |

That worked, but playback and the compression test still shows the those artifacts.
It's not a problem when encoding a full film, but when doing the compression test every 4-5 skips there are some artificats. I guess it shouldn't be a big deal. Thanks anyways |

I had the same problem on Windows Server 2008 64-bit.
I couldn't get wmvideo dmo decoder to work at all. Then I tried ffdshow in combination with wmv9 decoder, but in Vdub there were artefacts that you described as well. I figured it's a decoding issue. Are you sure the glitches aren't present in your encoding, despite them showing up in Vdub? |
