DGAVCDec 1.0.9

@Kurth

Thank you for the problematic streams. That is just what I need to iron out the wrinkles. I have only x264-generated streams to work with until now. They all worked fine. I will fix this for future releases.

Great work.
But i don't have real index as your demo with sonic cinevision.


Just that:

DGAVCIndexFile1

C:\Documents and Settings\Administrateur\Mes documents\CineVision Encodes\untitled1.264

SPS 6
FPS 50000 / 2000
PPS 67
SIZ 720 x 576
IDR 117 0
PPS 749843
PPS 1499831 and etc..........

Thanks.

Seems to do not work with mbaff streams :

The playback simply doesn't begin.

I can play this streams with mplayer.

To help you, I need the 264 stream. Thank you.

[tomos]

is there a way to check if the video is mbaff or not?

the first i have tried doesnt work for me. (raw 264 demuxed via mplayer from TS)

i tried the test file supplied with dgavc and the raw file. both are accepted and indexed with no probs at all.

i have 2 files, raw.dga and test.dga

with the same avs script:

AVCSource("whatever.dga")

the test works fine in vdub, but the demuxed video gives errors saying it cant load the dll file - DGAVCDecode.dll

then i try again and all of a sudden it loads in vdub. but if i move forward one frame forward then vdub closed itself down instantly. no errors, just gone. same if i drop the avs onto mpc.

i will try other files and test them

@tomos

We are in a mode of fixing support for different streams. So you have to give me the streams if you want them to be supported. I can't wave a magic wand; I have to analyze the stream to see what features I am missing.

Regarding the DLL loading, please take them (but not DGAVCDecode.dll!) out of your Avisynth plugins folder (or whatever) and put them into /Windows/System32 as I said in an earlier post.

Fantastic works!

Well btw, is it about to support index and read avc-in-mp4?

[tomos]

sample 1 (this indexes ok but crashes MPC/vdub etc)

http://www.mytempdir.com/1229927

sample 2 (this also indexes fine but shows as 0 frames in vdub - there's over a 1000 in the sample)

I did some poking around. DGAVCDEC was able to index the raw AVC stream of a full length movie encode just fine. I muxed the same stream into different containers and tried those next. The AVI one also got indexed fine, but I faced problems with the MP4 and the MKV one. For MKV, I get an 'undefined level' and the MP4 just crashes DGAVCDEC kicking off the Dr. Watson debugger. Not sure if you wanted a sample?

Looks like the SPS, PPS, IDR values are container dependent because they are different in the dga files of the raw AVC and the AVC in AVI one. But both decoded just fine.

http://x264.nl/h.264.samples/

Many different satellite streams, all H.264.
If all those work, we are finally getting somewhere with H.264

Hopefully, unlike mkvtoolnix, 10+GB files are not a problem with this filter.


Time i have not, bandwidth i have..... enjoy testing

i dont think its necessary to index mp4, as mp4 has an index

[Guest]

@MeteorRain

Of course! But you have to walk before you can run.

@bond

The idea is to support the container so that demuxing is not required.

@tomos

Thank you. Your streams are in the hopper for analysis.

@unskinnyoby

As stated in the help file, only ES is currently supported.

@bob0r

Thank you. I will test those streams.

@all

I have enough streams to fix for now. Please defer further reports until the next beta.

[leiming2006]

This filter didn't work well here.

this is avs script:

fs="F:\11.dga"
loadplugin("d:\avs\DGAVCDecode.dll")
avcsource(fs)

and this is the error:

[Guest]

It's not finding the DLLs. Please read this thread carefully.

If that can help you

@neuron2:

Thanks for the effort.
I don't know whether you have already received any samples from BBC HD, but the fact is, there is no IDR frame in BBC HD at all. I'll send sample if you want.

[Guest]

Thank you. I'll ask for it later. I have my hands full right now fixing issues with libavcodec.

[Blue_MiSfit]

Thanks neuron2!

Amazing results, I get between 80fps (for complex scenes) and 130fps (for black and credits etc) decoding speed, compared to 60-110fps for directshowsource("F:\Movies\The Departed.mkv", fps=23.976, convertfps=true), which uses haali's splitter, and ffdshow for decoding.

Note that my source was made by x264, it's high profile with CABAC, 704x352, 4 references, default matrix. [ot] My most recent backup actually, which I was very VERY happy with the results... I was able to improve image quality over the source with some gentle denoising and sharpening - AND reduce the file size by about 75% (2.2 GB vs ~9GB) [/ot]

Impressive results! Of course, the added time to demux and index sort of negates any advantage this might present, but I'm always happy to not use DirectShow!

A welcome addition to our swiss army frameserver

Please excuse my stupidity, but what is this filter for?

DGAVCIndex will of course have a preview like DGIndex and it will accept the container formats directly. Right now, I am getting the decoding correct. There are some problems with the interface to libavcodec, but Michael and I are working them out.

Thank you for your test results.
