How to demux VC1 elementary stream from WMV file?

[mixja]

I didn't forget about this; it is indeed a "special case" in the spec that's complex enough where I'd need a sample file to update my program reliably. And it took me until now (well, I wasn't exactly working full time;) to get such a sample. Now I can start on the actual fix, maybe add a few other things too (e.g. PAR and frame rate command line override switches). It'll probably be another week before I actually finish the update, though.

Any further updates/progress on this yet?

Thanks a lot stegre for ASF2VC1.

I've never ever succeded with VC_1 ES writer v.0.2 on GraphEdit before.

Now the VC1 files demuxed by this command utility work very well with modern muxers which means i can get WVC1 files as wmv via MS Expression Encoder2 and demux encoded wmv files to VC1 .

So i'm ready to make my own BluRay Disks in VC1 anymore :)

:thanks:

OK. The first trial:

http://rapidshare.com/files/130507856/BD_VC1.rar.html

Original was h264 1440*1088i HDTV broadcast.

Encoded to 720p wmv (WVC1) with MS Expression Encoder2.(just video)

(method: graph based avs was the source file-without audio- and mpc source(gabest) and Cyberlink h264 decoder(PDVD7) has been used in this graph)

Demuxed to VC1 via ASF2VC1. (video)

Audio demuxed with "dump" filter from the original ts file as "mpa" with graphedit.

Both files remuxed to BD with TSMuxer.

EDIT: Sorry, i've just awared i left the video as "letter box" while encoding.

I tried to demux a VC1 stream from a WMV file and also came across this
"Warning: ASF ReplicatedLen of '1' not handled yet; ignoring." issue. Are there any solutions or workarounds for this yet?

I get around that issue by muxing to mkv first with dsmux (or gdsmux if you want a gui) included with Haali's mkv splitter package, and then muxing it into a m2ts container with tsMuxer. If you must have a raw stream, you should be able to demux it directly from the mkv using tsMuxer.

Hi,
I used the tool for demuxing the WMV streams with multiple slices to VC1 stream. The demuxing seems to be going on well but the reference decoder terminates early with out any message. I tried to debug with out much success. For files without multiple slice the decoder works properly. I am wondering if the slices SCP
(0x0e) are missed while demuxing . I used trail version of mindigo analyser it seems to analyze the stream properly but I am clueless why it fails with ref decoder.
Any pointers??
Do you think this is limitation with demuxer?
