Problem loading Full HD content [Archive]

As the title says, I cannot correctly load 1088p content in AviSynth scripts...
When I use DirectShowSource (both directly on the m2ts file and on the filtergraph), the script introduces some sort of line-doubling effect, which makes the result look bad...

Comparing the images, you can see that the scripts (actually it's one line of DirectShowSource) modifies the proportions of the frames, it crops the 1088p to 1080p, then it scales back to 1088p, which cause the introduction of new lines...

I don't think it's a problem of decoder, cause the "original" picture was taken with the same one...

How can I fix this?

What decoder are you using?

I was using Cyberlink...
Solved now... using DGAVCIndex

I want to reopen this thread...

DGAVCIndex crashes with some streams, so I need to use DirectShowSource() to import a 1080p AVC stream...

Basically the problem is that the frames are resized from 1080p to 1088p, adding 1 line every 135 (136 * 8 = 1088)...

How can I import 1080p streams correctly?

Surely it's still down to the decoder, not AVIsynth?

Have you tried ffdshow? It works for my m2t files from a camcorder, but I've not tried AVC.

Cheers,

How can I import 1080p streams correctly? You can try making a graph in Graphedit and then attaching to it with your script.

I would also try CoreAVC.

Ok... the issue seems to be decoder-related... Cyberlink output in 1088p, which is wrong...

try another decoder. coreavc is cheap and fast.

Yeah. CoreAVC forced via a GraphEdit .grf and loaded with directshowsource works very well indeed. AFAIK it's also the fastest solution since it's multithreaded.

If only we could get it working (cleanly) with the Cyberlink decoder for DXVA (for us hardware accelerated ppl)
