Hmmm, it's right in the DGAVCDec package--and you have read the included docs, yes?

[Guest]

The docs don't (currently) specify the source code version I used, so his was a quite reasonable question, given that he is trying to rebuild the DLL I ship.

Ah, sorry komisar I misunderstood your intentions.

[komisar]

neuron2, ok. I grab all for my need but:

I have made a small modification to return a different version string to
manage compatibility issues. This modification is available on request.

Can I "request" this modification?

Here is my modified src/ffmpeg directory:

http://neuron2.net/misc/ffmpeg1837dg.zip

Please coordinate any release of a new libavcodec.dll with me please, as it is quite easy to break DGAVCDec functionality if you upgrade to more recent ffmpeg code.

neuron2, THNX.
Ok. No problem. If I successfully build what i need -- i am post patch here.

neuron2, latest version of ffdshow-tryout not work correctly. Version of 1837 with h264_predictive_lossless2.diff non-lossless open correctly, lossless -- open with message

show first frame correctly, but crash with save .dga or play [F5]
tested with dgavcdec107.zip

P.S. latest ffdshow-tryout and dgavcdec100a35.zip work (without h264_predictive_lossless2.diff).

@neuron
Could you check this sample http://www.mediafire.com/?ymugtm4zhnj

DGAVCindex reports insane audio delay (CANALplus.FILM.HD.Nordic.Thor.0.8W.10jul.2007 PID 281 3_2ch 384Kbps DELAY -45759574ms.ac3).
eac3to reports -241ms

I've been working on audio delay for the last two days and found quite a few bugs. It's now working well in my private build, which fixes your stream.

The canTsTop stream is a different matter. It has the AVC equivalent of the problem we sometimes saw with DGIndex where you have to start your project in by a GOP. It's a pathologic stream and I wrote a timestamps analysis tool to prove it. For that stream, starting in by a GOP together with the fixes I mentioned produces a good result. I'll explain it all in detail when I make the release. I just have to do some regression testing.

BTW, I am removing the Treat I as IDR option. There's no reason not to have it on always. Speak up now if you disagree.

[Sagekilla]

is h264_predictive_lossless2.diff the one that changes the lossless mode from intra --> inter frame based?

If it is, that's why ffdshow-tryouts won't open it. No decoder except CoreAVC (I think) supports predictive lossless.

If you give me the changes I can try to debug it for you.

It may appear to work for simple streams but random access is broken with many of my test streams. Anyway, why use such an old version of DGAVCDec?

I am forgot to update the version...

[Guest]

As the changes were extensive, I'd like to get some testing on this before a release.

@Atak_Snajpera

It fixes your bug.

@canTsTop

Your stream has an issue at the beginning. After loading your file, hit the > button and then the [ button to start the project in by one GOP. Then Save project.

Test results will be appreciated. Thank you.

This way i get correct a/v synchronization

And with this new version i can see difference in other video, now i get perfect synchronization. i made samples if anyone interest, difference is small but exist:
with old DGAVCIndex: http://www.mediafire.com/file/ulgogijzmnu/old.avi
with new DGAVCIndex: http://www.mediafire.com/file/2j231mdmtz1/new.avi

Thank You neuron2 very much

p.s. with this new version dgavcindex108test, i get this warning then i save project, is it normal?

with dgavcdec107 there is no such warning

[Guest]

For the error popup, can you give me a stream? Thank you.
