decoding truly interlaced 1080i VC1

Blue_MiSfit · 10th July 2008, 01:23

Can this be done outside of proprietary players? I'm trying to decode a title into AviSynth for re-encoding, and can't seem to get it working..

Suggestions?

I suggest that you tell us what your input file format is and you tell us exactly what problem you are running into. Your script as well.

Alright.

As the title suggests, my input file format is VC-1 1080i from a BluRay disc, stored in the MKV container. I processed the BluRay with eac3to, and demuxed the audio to ac3, and remuxed the video only to an MKV.

That part works fine, the problem arises when I try to load this MKV into AviSynth.

My usual workflow is to just use directshowsource("movie.mkv", audio=false). This time, I get the following error:

Code:

DirectShowSource: couldn't open file "movie.mkv": 
No combination of filters could be found to render the stream

My script is just DirectShowSource(...)

I tried mucking around in GraphStudio to build a filter graph, but haven't had any success.

It has always worked in the past, but I have never processed true 1080i content before.

I'm running Vista x64 edition, for reference

Your title doesn't suggest that.

I forgot the whole VC1 thing

try to use a ffmpegsource()

Tried that as well, and it bombs out with an explosive error log after about 10 minutes. The source file is large (13 GB), so that may have something to do with it.

I am having a similar problem with a VC-1 encoded blu-ray. I have backed up my main movie (VC1 1080p 23.976) to h.264 mkv with no problems but nothing I have can even read the special features. I can watch them playing the movie as a blu-ray from the disk, but the m2ts seem to be unreadable. Even Nero reads the 1080p streams just fine but can't read the 1080i streams.

What's confusing is that TSMuxer reports them as 1080i 29.97 but eac3to reports them as 1080i60/1.001.

I've tried remuxing them with TSMuxer and VC1conv with no success. Does anyone know of a utility that can read or convert these VC1 streams into something that can be read by avisynth?

Why is interlaced VC-1 being treated any differently than progressive VC-1 by the parsers?

rica · 17th August 2008, 14:21

To my trials VC1 is a little bit complicated than h264.
I think it is not related with the VC1 is interlaced.
If you are extracting video with eac3to and put into the mkv container (BTW eac3to uses Haali muxer which is the source of the issue) you will always live issues.

Extracting to VC1 instead of mkv will solve the problem;

Thanks very much rica. I haven't used GraphEdit or created Avi synth scripts before, but I think I can work out what to do from your posts. I'll give it a try and let you know how I go.

To date I have been using AutoMKV for my conversions...

I would be very interested to get samples of interlaced VC1 for testing DGVC1DecNV. Thank you.
