Ive placed the .dll into plugins folder. Any advice?

Thanks in advance.

Why not keep the .dll file in the original installation directory? It works perfectly fine here with Megui for MANY encodings.

loadplugin("D:\utils\encoding\dgavcdec\DGAVCDecode.dll")
#loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\decomb.dll")
avcsource("__vid__")

Thanks for a great program Neuron2, didn't fail me yet for Sky HD broadcasts :-)

@neuron2

Since the absense of Haali, due to real life issues, i'll have to ask you:
Can you make a fix for itv.h.264.1440x1080.ts its detected as MPEG2, forcing -demuxer h264es with mplayer.exe got me the proper raw file.
Demuxing with dgavcdec gets me a wrong .avc file.

And if you are in the mood for fixing:

04-13_18-59-45_CANALPLUS_FILM_HD_(AC3)_Sentinel_The.ts has no audio stream detected, also Haali's gdsmux.exe creates a choppy .mkv using that file, so something is wrong with that .ts also.

+ i have some old swiss hd capture aswell, which crashes with dgavcdec, can you check it out and see what the errors in this .ts file is?

Everything worked fine for me with this one (using alpha 23). The demuxed AVC file opened again fine in DGAVCIndex. Why do you think it is "wrong"?

Just to let you know... All ITV HDTV streams are "experimental". So there PID's are all over the place!

Currently ITV does not have an HDTV broadcast platform in the UK. Only BBC, C4, Discovery, Sky and some other misc channels do

@Neuron2

When i remux the .avc and .ac3 in .mkv, its all slowed down, MPC reports 4fps or so.

When i demux the .ts with mplayer.exe, the .264 file is also much bigger.

Assuming the demuxed .avc and .ac3 file with dgavcdec should be remuxable (Delay doesn't matter, but it should play 25fps, when muxed as 25fps in mkvtoolnix)

My goal: Cut out the DEMO-LOOP as clean .ts or .mkv file, .mkv prefered.

But as of now, Haali cant even open the .ts to begin with.

@SeeMoreDigital
Indeed, but i did managed to capture the .ts file, using the settings a doom9 member gave me.
All i want is a working .mkv cut from the .ts file.

[bob0r]

I solved my issue using http://www.videohelp.com/tools/TsRemux
The remuxed .ts can now be opened with Haali's gdsmux.exe.

Both .avs demuxed are the same, so dgavcdec is correct.
Ill ask Mosu to fix this issue when he is alive, same goes for Haali.

Thanks!

Any luck on the broken swiss hd .ts?

I tried mkvtoolnix 2.2.0 and set the FPS in the Format specific options tab. Everything worked fine and the output was an MKV that played at 25fps and was reported as such by MPC. I don't know if it is relevant but I named the raw AVC file with a '.264' extension.

Alpha 23 detects an AC3 and an MP2 and I can demux both of them.

Hmm indeed i see it also now, weird, thanks for checking them!

mkvtoolnix: 2.1.0: http://files.x264.nl/itv.hd.remux.choppy.mkv
mkvtoolnix: 2.2.0: same result, can you share a sample of your .mkv?

No point, really, because yours plays just fine and smooth for me.

What AVC codec are you using?

[Flaarn]

Ok , I'll jump in here, there will be some oddities if you capture further test streams with itv hd, as they are playing with the parameters right now, in the last few hours they have been playing with the audio channels, ie left/right channel testing.
It reminds me of the very early bbc hd testing, but at least there are some dvb apps out there that can handle it now, basically expect some further strangeness for a few days until it goes "live".

CoreAVC Decoder :O)

Guess we just found another .mkv/coreavc bug (as .ts plays just fine)


I have another question for you Neuron:
Pengvado just told me a little about colorspaces and the matrixes used (tv/pc level) My question: Does dgavcdec (libavcodec) always set the same level as the source is?

"Is dgavcdec "decoding" the video and serving the results to the encoder, or does it work another way"?

DGAVCDec passes the YV12 through as is.

"Is dgavcdec "decoding" the video and serving the results to the encoder, or does it work another way"?

DGAVCDec decodes the video using libavcodec and passes uncompressed video out via Avisynth using DGAVCDecode.dll.

I'm having issues with another movie now... for one thing the # of frames is too short and thus the length doesn't match up with DirectShowSource or the PS3.

Here's a chunk, I'm not sure how much this will help since it doesn't seem to have the same shorter length issue. Here the # of frames appears the same in DGAVCIndex and DirectShowSource but less with AVCSource. The full movie has seeking issues with AVCSource, and so does this clip. "Go to" frame 67 and it's different than if you seek to it from 0. "Go to" frame 100 = Visual C++ runtime error.

Hi neuron,

i'm doing a test and i'm simulating an "avc-intra" compression.
So, to get it, i managed megui to have GOP=1 and minimum i-frame interval to 1, to be sure to have only I-frame encode.

Since i'm calculating some sessions of SSIM and PSNR, i used DGAVC to prepare the comparison script.
but i've noticed that dgavc sees only one frame of my clip. (i tried to play it in mpc and it is ok).
i hope to have explained myself...

pls let me know if there is a solution.

thanks!
ciao

@Gannjunior

I need a stream that allows me to duplicate your issue.

[Gannjunior]

here it is neuron. thanks!
