No decompressor for x264

[varunb]

Whenever i try to play x264 encoded videos using avisynth ( using avisource ), i get an error saying "Couldn't locate a decompressor for x264............" something like this. When i replace avisource wiht directshowsource, it plays smoothly. I dont understand y i am getting this error even though i have set H264 option to libavcodec in VFW decoder window in FFdshow. I even switched from 'ffdshow_rev598_20061127_clsid' to 'ffdshow_rev610_20061201_clsid' but it still didn't solv the prob. I hav noticed that the avi file plays fine on MPC & also opens in graphedit without any prob but when i open it in virtualdub, it says 'since there is no decompressor, so only direct stream copy option will b available'. Can u help guyz ??

Install ffdshow.

Personally I would just stick to directshowsource. But others more informed might provide a more usefull answer.

Did you even read the post? :confused:

it seems you try to open an avi format file containing x264 encoded content... I don't know why you can't open the file even though you have set the H264 option to libavcodec in ffdshow VFW decoder but another thing you can try is installing an x264 VfW build.

x264 has no decoder, so installing it won't help.

Maybe ffdshow VfW isn't installed properly? Certainly if it is installed and enabled for the fourCC, then it should be used to decode. Try configuring via VDub rather than the startup menu shortcut.

Thanx for looking into my prob guyz but i hav solved the problem now. I just restarted my pc, installed ffdshow rev610(generic) again & its working now. Even the avisource option is working. dunno y it didn't work before rebooting.

Probably a buggy version of ffdshow or it was just screwed.
