VC-1 Encoder SDK - Professional released

[lazyn00b]

http://www.microsoft.com/downloads/d...playlang=en&tm

"The Microsoft VC-1 Encoder SDK - Professional is designed to provide file-based and/or real-time encoding capability to general content creation toolsets or dedicated encoding software applications.

Optimizations and features include:

• Can output VC-1 Elementary Streams for delivery in HD Optical Disc applications
• Performance improvements over the Windows Media FSDK11 for the latest generation of processors from Intel and AMD
• Perceptual quality improvements over the Windows Media FSDK11
• Ability to control all advanced settings programmatically through the API (no registry key settings required)
• Native Hardware Acceleration API support"

Does this mean someone can finally design a free GUI to encode HD DVD/Blu-Ray compatible VC-1 streams?

[mahsah]

Woo, finally an ES encoder!

[Sagittaire]

Well ... someone can compile RAW2ES and AVI2ASF (Visual Studio) for make test ... ???

[crypto]

Well, I tried, but the samples do not link:

fatal error C1900: Il mismatch between 'P1' version '20060201' and 'P2' version '20050411'
1>LINK : fatal error LNK1257: code generation failed

Edit: Seems to require SP1, I am currently downloading
Edit 2: That did the trick. SP1 update for Vista was also needed:

Here are the compiled VC-1 sample encoders: VC1ProSDK-samples.zip

I've modified the AVI2ASF sample to include:

• Avisynth (.avs) YV12 file support
• Encoding to both .vc1 ES streams and .asf files

There's more information in the Readme.txt. Source included.

Cheers,

Nic, damn you're fast. I was just adding compressed AVI support, but your mod is better.

[Kurtnoise]

which splitter/decoder is required to play those files ?

[Nic]

Very little seems to be able to play .vc1 files. VideoLan can't nor can anything I've currently got installed. However, Nero 8's Showtime with the HDDVD plugin would be able to play it.

[crypto]

Splitters for VC-1 ES files:
- Sonic HD Demuxer
- V9E Parser (included in the SDK)

Decoders:
- WMVideo Decoder DMO (WMP 11 or WMF 11)
- Sonic Cinemaster Video Decoder >= 4.1
- FFDShow
- Cyberlink VC-1 Decoder (PowerDVD)

[Sagittaire]

Well this VC1 encoder is not able to produce HDDVD compliant stream (no telecine for pulldown flags).

[Nic]

It should be able to produce HDDVD compliant streams - what do you mean exactly by "no telecine for pulldown flags"? Maybe I can add whatever you need to the sample.

How are you checking compliance?

-Nic

[buzzqw]

would be possible to include support for audio ? (wma std/pro)

so will have a command line application able to encode video AND/OR audio and outputting asf (only video), asf (audio and video), wma (only audio).. and what about WMV output ?

and remove the "press input" final...

thanks!

BHH

EDIT: -threads is broken
feeding audiodubbed avs will produce biiiig files (must ctrl+c...)
EDIT2: even feeding audidubbed and specifing -pr audio profile will not close the encoding

• Can output VC-1 Elementary Streams for delivery in HD Optical Disc applications

How do i get a HD compatible vc1 output from this?
I tried with a 1 minute sample.evo avs

DirectShowSource ("sample.evo",audio=false)
ConvertFPS(24000, 1001)
spline36resize(1280,720)
ConvertToYV12()

I used this command...

AVS2ASF -i sample.avs -o output.vc1 -framerate 23.976 -rate 8000 -ratecontrol 3 -profiletype 2 -bframes 2 -maxkeydist 6 -vbv 300000 -peakrate 28000

Encode took more then 10 minutes

Cinevision(Mui Generator) does not accept this stream, getting error...

No Sequence-Layer just before Entry-Point ??

Well I have a special VC1 encoder (command line from pep) and you must add telecine flag for produce HDDVD NTSC compliant stream. These flags simulate 1080i30 interlaced stream with internal 1080p24 progressive stream.


Here command line for "HDDVD stream" without pulldown 3:2 flag

AVS2ASF.exe -i HDDVD.avs -o ElementryStream.vc1 -framerate 23.976 -ratecontrol 3 -rate 6000 -peakrate 20000 -vbv 1843200 -complexity 5 -profiletype 2 -bframes 1 -maxkeydist 14 -inloop 1 -motionsearchlevel 3 -mesearchmethod 2 -mbcost 1 -mvcost 1 -mvrange 4 -adaptiveGOP -videotype 0

http://nic.dnsalias.com/AVS2ASF.zip <-- new v0.2

@lance79: Please try the new version. Should solve that issue. (I was creating ES rather than ES_SH streams (ES_SH is needed for HDDVD compatability).

@buzzqw: Did you provide a .prx (Windows Media Profile) file for audio encoding? That should solve it. I'll try to make some and provide them in the .zip file for future versions. For -threads you also need to provide an -affinity switch to state the processor layout. Try -threads 2 -affinity 3 (or 1). Can't test here as I don't have a 2 processor machine handy.

@Sagittaire: Hmm quite specific. I can specify specifc TFF and RFF flags for every frame. Could that help?

-Nic

[buzzqw]

when setting -threads 2 -affinity 3 (or 1)

got this error

Encoding in ASF mode

Failure in CVC1EncASF::set_advancedProps
error = -20
Failure in CVC1EncASF::Init
hr = 0
VC1 SDK Error = -20

Final error code: -20
Total elapsed time in seconds = 0.031000

and even if providing a prx audio file (namely d6_qvbr_75_audio.prx , taken from program files\windows media components\encoder\settings) the encoding will not conclude. fyi i am using nicac3source feeding 2 channel ac3

[lance79]

Thx Nic, gonna give it another try...

[Nic]

http://nic.dnsalias.com/AVS2ASF.zip <-- v0.3

AviSynth (2.56 at least) doesn't seem to report no more audio frames even if requesting a sample beyond the total number. Hence the audio would encode forever. Hopefully this quick fix to avs2asf should workaround the problem.

The threads issue I cannot debug now - but it should be using the maximum number of CPUs it can by default anyway.

-Nic

[buzzqw]

Audio is FIXED!!!

... about cpu.. not a big problem.. but just 1 core is used

thanks again!

dumb question: from asf to wmv.. it's just a matter of renaming file ?

EDIT: no 5.1 audio support...

"but just 1 core is used" <--- Not much I can probably do to fix that even when I get on a dual core machine

from asf to wmv.. it's just a matter of renaming file ?

Yup, and you can use .wmv (instead of .asf) as the file extension too with avs2asf to save time renaming later
