It's just hard 3:2 pulldown. You can use this script:

AVCSource("20080817152150.dga")
assumetff()
telecide()
decimate()

Further discussion about undoing pulldown should be taken to the Avisynth forum.

Watch out using clips from that camera in DGAVCDecode. I know from personal experience that you're likely to run into some known artifact issues with the PAFF streams produced by it. The NV version does not have this problem, but requires a donation and an Nvidia card to use.

Thx for pointing this out. Donated already since I also need it for BluRay.

I don't understand all the issue(s) with libavcodec, but it seems from a casual look at the ffdshow changelogs that a lot of changes have been made since the date of the file you made for DGAVCDec. Might it be possible there's a better/newer version to use with DGAVCDec?

Feel free to shoot me if I'm completely off-base somehow.

BANG! I've answered that several times.

There are regressions in functionality needed for random access that the developers appear to be uninterested in fixing, or which they consider to be too low in priority to ever get worked on.

I'll look again this evening at the status of the critical bug reports.

OWWWW! Yeah, I know--I read your many posts about this but I'm not smart enough to correlate ffdshow's change log entries to your issue (and didn't know how to seek the bug reports). Anyway thanks for looking again.

If no progress can be made I will try to be patient til my Nvidia system is done, after which you will be hearing from my banker, er, I mean PayPal, for the NV versions of your tools.

The ffmpeg issue tracker appears to be down. Does anyone know anything about that?

Nah, I need the tracker to see if the known bugs have been addressed. Can't remember the bug numbers.

EDIT: I just built and tested ffmpeg16456. The bugs are still present.

neuron2, can you describe ffmpeg-bug more detail?

Maybe we can solve this problem through joint efforts? ("we" -- Those who are interested in using dgavcdec; "solve" -- do make correct patch)

P.S. Oh, sorry for my bad English. I check translate.google.com

When the issue tracker comes back up we can discuss it.

Can you translate this into understandable English, please? Who is "we"? What does "are solve" mean?

He made a mistake so what? I understand what he meant! Is that difficult to replace 'are' with 'can'???

Thank you for notifying us.

The killer for me is Issue 475.

https://roundup.mplayerhq.hu/roundup/ffmpeg/issue475

I have several files that do this. As upgrading is a big effort, I prefer to wait until this major issue in PAFF support is fixed. Note that after more than 6 months it is still unassigned.

you mention regressions for random access, is it only for this kind of files (AVCHD) or is it an other issue ?

Remaining PAFF bugs are the main issue. I don't know if it is just AVCHD.

The decoder is now returning orphaned B frames at the start, which it doesn't do in the older version I use. That's not strictly a regression and I can re-architect around that, as that is the way that the CUDA version works.

i am not expert , but if i understand correctly Issue 475 (https://roundup.mplayerhq.hu/roundup/ffmpeg/issue475) have problems with ffmpeg but not libavcodec. i had same problem with ffmpeg, Issue 721 (https://roundup.mplayerhq.hu/roundup/ffmpeg/issue721), but if play that sample in mpc+ffdshow there is no problems.

is there are any samples that current version of ffdshow cant decode correctly?

That's very interesting!

I'll see if they play correctly using ffdshow. Is it ffdshow-tryout? Please tell me the exact version you are using.

If things are OK, I will upgrade from that code base.
