DGAVCDec 1.0.9

ok, thankyou for answer

[Guest]

Out of interest, have you actually verified that any version of ffdshow-tryout or ffmpeg actually fixes these PAFF errors.

I just tried ffdshow-tryout rev 2060 and there are regressions all over the place. And the PAFF errors are still there. I haven't tried latest ffmpeg yet, because it won't compile for me.

I've also sent an email to Michael Niedermayer asking him what he knows about it.

@neuron2

i didn't try it, i just searched here http://svn.mplayerhq.hu/ffmpeg/trunk...odec/?view=log for PAFF and in previous month mailing list her http://lists.mplayerhq.hu/pipermail/...ly/thread.html (also search for paff)

i compiled using this guide http://arrozcru.no-ip.org/ffmpeg_wik...?page=HomePage

[Guest]

Please give me a link to your ffmpeg.exe and libavcode.dll compiled from the latest ffmpeg SVN. As I said, it won't compile for me and I'm well aware of the wiki you linked.

[canTsTop]

here is my compile http://www.mediafire.com/?44tmqrmejvr

for some reason libavcodec.dll is named avcodec.dll

Huh. Strangely enough, FAAD decodes this AAC encode successfully.
Previously, I had files which foobar2000 would not play, saying "Decoder produced garbage" and DirectShowSource() would fail to open (they came from Japanese TS files, and this would happen about half the time).

FAAD would also error on each of those files, but muxing these files into a mp4 and then doing whatever on them would work.
Only this time, FAAD *does* work and it seems that remuxing to mp4 ate a small chunk from the start (the "decoder produced garbage" part).

The world of A/V is a weird one x_x

Sorry for bothering you :X

OK, I have the latest ffmpeg compiled now.

The first PAFF stream I tried with ffmpeg.exe that was broken before now plays well. That's a good sign. I will test all my bad PAFF streams and report back.

Michael informs me that he right this moment is still fixing PAFF bugs. We may want to wait until he completes that effort before making an update to DGAVCDec.

could you upload your latest ffmpeg build?

Static build:

[Atak_Snajpera]

Why revision number is missing? Which revision did you compile?

Thanks!

[Guest]

Don't know why the number is missing. Probably a result of the build problems I had. I compiled the version I retrieved from trunk today. Can't remember the number, sorry.

Hi,

i've got following problem:
I used DGAVCDecIndex 1.0.0. alpha 33 to index a h264 file...
so it created a XX.dga file.
Then I installed Avisynth 2.5.7 copied the "DGAVCDecode.dll" into the Plugin folder and then I created following avs-script:

loadplugin("C:\Program Files\AviSynth 2.5\plugins\DGAVCDecode.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll")
avcsource("D:\xx.dga")

Indexing and anything else went fine...but then I wanted to use this .AVS in TMPGenc Plus V.2.524.63.181. There I tried to load thi AVSscript as Video Source but then there comes up this error message:

File: "d:\xx.avs" can not open, or unsupported

Where is the mistake ?

Thanks in advance for your help!

[Guest]

Remove the loadplugin lines. If they are in the plugins directory, those lines are not needed.

If it still fails, try to open the script in VirtualDub. What happens?

I have the same version of TMPGEnc and everything works fine for me.

Hi Guys,

I´m having some problems converting HDTV h264 1080i material to 720p x264 material.
Usually this works like a charm. But PremiereHD changes their video-stream.
They OBVIOUSLY reduced the bitrate massively and try to keep the picture stable
by using h264-codec features. "tsMuxer" tells me (for example) they are using
bPyramid Level1 + bPyramid Level 2. So far no matter for me, but now I get unuseable ugly
pictures in the converted Video.

See this screenshot:

It´s clearly visible that it comes with movement in the picture (over the Frames).
When the picture is still...there are no artifacts.

I´d say it´s the fault of DGAVCIndex, maybe the decoder from DGAVCindex...that would be "libavcodec.dll".

I´d like to repeat..the problem comes with the new "type" of videostream PremiereHD is broadcasting.
I converted older material from PremiereHD with the 100% same software (MeGui, rel. of x264, ect)
with absolutely no errors/artifacts in the pictures of the transcoded video.
Of course the picture in the original stream is okay, when played.

Any hint that to do?

What do you have in your avs script when converting it?

Wait patiently for a while. PAFF bugs are currently being fixed by the ffmpeg team, and I will be updating DGAVCDec soon with the fixes.

I don´t know what interest you seek here, but here you are:

program --bitrate 5500 --level 4.1 --keyint 125 --min-keyint 1 --ref 2 --mixed-refs --bframes 2 --bime --weightb --nf
--partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --ipratio 1.1 --pbratio 1.1 --vbv-bufsize 18000 --vbv-maxrate 26000 --qcomp 0.5
--merange 12 --threads auto --thread-input --progress --no-psnr --no-ssim --output "output" "input" --mvrange 511 --aud --nal-hrd

So I take it, I was right...it´s "libavcodec.dll" and I need to wait to get it fixed by them, so you can Update yourself.
Thanks for the info! @neuron

/EDIT: @neuron: You´d like a sample of that video-stream for future reference, or own testing?

/EDIT2: whoops...you asked for the avs-script

Loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\DGAVCDecode.dll")
AVCSource("Trennung mit Hindernissen.dga")
#LeakKernelDeint(order=-1)
#Crop(0,0,-0,-8)
LanczosResize(1280,720)

You might wonder why there is no Deinterlace made...since I learned from neuron what any why video needs to be deinterlaced
I decide NOT to deinterlace here, because PremiereHD usually (to me always) broadcasts material which doesn´t need any deinterlacing.

[Guest]

Yes, I would like the stream sample, please. Thank you for offering it.

[Rodger]

No prob!

Here it is:

[JediNight]

I've been trying for a few hours now to make a TS workable, and I just can't seem to do it. I can get it to open in MPC-HC, but any seeking crashes it. Any attempt to demux it with Xport, TSconverter, mplayer, etc. has failed to result in a file recognizable to either X264, DGAVCindex, or Vdub.

It's a 720p H264 TS file. I would cut a clip, but if I can't open it other than MPC-HC, I don't know how to actually do that.

Any ideas or what more info would you like from me?
