Slight difference in audio output delay

I've added it in my local build. But there is an issue with accuracy of the marks versus the displayed GOPs (for TS), i.e, if you navigate on the timeline to a chapter mark it is close to but not exactly at the intended video. The reason for this is that the chapter marks specify times and they are ...

Try checking skip first M2TS in the options.

I knew you'd ask for that.

Re-download again and update DGIndexNV. Fixed another MKV 'GOP back' bug that led to a very busy tight loop for some unlucky streams. :oops:

Seems real good now.

Please re-download again to get chapter marks on the timeline for MKV.

May add that for other containers in the future. Also, may support XML chapters file for the other containers. I'd like to get this version released first.

Slight difference in audio output delay

Please re-download for the next test version. It eliminates the need for mkvextract to extract chapters by doing it internally. The old MKV parser library previously did not parse chapters and that's why I used mkvextract. So I bit the bullet and added chapters parsing to the library. Gonna need it ...

HEVC 4:4:4 support

Not supported but there's no reason it couldn't be supported if NVDec is happy with it. All I need is a sample. ;)

In general right now, we have AVC, HEVC, MPEG2, and VC1 all in 4:2:0.

Maybe we could do lossless now too.

Cool, thank you.

I encoded Baywatch without issues. Well, there was one issue but not mine. Apparently x265.exe wants mod 8.

Also put Reverse() at the end of several scripts to test random access on every frame. No issues.

I might do chapter marks on the timeline next.

You lost me on that one. I'm gonna assume you meant that the test build is OK (so far). Squirrels are not good at reading between the lines. We are very literal, if not very literate.

Update both components and don't try to re-use existing DGI files.

Let's see how much stuff got broken. ;)

GOP step error for some MKV streams

After I got forward stepping working reliably I found that backward stepping was hosed. Reliable GOP navigation is important to set accurate project ranges, of course. Anyway, I just got that fixed this morning and as I mentioned in another post will release a candidate version very soon, maybe today.

I've got the new generation indexing completed (I hope). It all stemmed from this MKV delay issue that got me investigating. I found that the MKV support was a gigantic kludge and so decided to revamp it. That had implications outside the MKV code so it became a massive testing effort. Think about i...

GOP step error for some MKV streams

Turns out this is not related to successive IDRs with the same idr_pic_id, and I imagined that it was fixed. Nevertheless that should be fixed. The real reason was very complex and difficult to find but I found it!

GOP step error for some MKV streams

For some MKV streams a GOP step produces a corrupted picture. We have a workaround for streams with successive IDR frames with the same idr_pic_id, but this was being applied only for ES streams. When applying it to all container types, the problem is fixed. I will release this along with the MKV re...

Slowness on pure decoding

I ran a test with pools 12:

no prefetch: 31.92 fps
prefetch 2: 29.5 fps

Hoping for clarification from your side on the 100% claim.

EDIT: OK, just saw your post above.

Will mark resolved.

MKV re-design is proceeding well, BTW.

Slowness on pure decoding

You initially wrote: "I have found, strangely, that adding a simple prefetch (2) at the end of the AVS script increases my fps by almost 100%." But the table you subsequently gave shows (for pools 12) an increase from 7.66 fps to 8.56 fps. How is that 100%? Such a small difference can be accounted f...

Great info, thank you. Will try to duplicate it.

You can try also with a different decoder to see if the same thing is seen. If so, it's unlikely we can do anything about it.
