Can't look at it until tonight as my firewall blocks media sites. Can you put it on an FTP?

Found and fixed the problem. Will be in the release. Thank you for your test results.

don: Do you still plan to release the source code for DGAVCIndex in the future? I seem to remember you saying it would be released when more stable versions were out, but that was back in the "alpha" days.

Just curious about this since it would be interesting to modify DGAVCIndex to output details similar to those in D2V files such as field-related flags. That would make it possible detect pulldown patterns and pattern transitions, and ultimately convert 1080i to 1080p for a lot of source material, using an external application to analyze the picture/field info. This method works very well for MPEG-2 and would probably work nicely for H.264 video as well.

That information is in the DGA file already. I've no plans at this time to release the source code.

Blind I am. Thanks for the help.

Looks like I'm dealing with highly inefficient encodings since the data in the DGA file indicates each and every field is coded separately (PIC 1 and PIC 2 only), even if the source material (MPEG-2) made use of the RFF flag. D'oh!

@neuron2,
I ran into some errors with a tile. I've put the clip here for you if you have time to look at it please.
http://rapidshare.com/files/177250361/clip.h264.html (IF YOU'RE NOT NEURON2, PLEASE DON'T DOWNLOAD THIS AS THERE IS A 10-DOWNLOAD LIMIT).

Plays clean in MPC HC and via directshow, but causes errors to pop up and then garbage in the image. I'm using 1.0.7.

It plays clean in DGAVCDecNV, so I conclude that it's a problem in the version of libavcodec that is used in DGAVCDec. The same problems appear in VLC.

Aha. Thanks for checking it out so quick. I have an ATI card in my system so I assume I can't use the nVidia version right?

That's right, it runs only on the Nvidia cards.

Neuron2:
ffdshow_tryouts project just released a new beta (23 dec 2008). Would an update of DGAVCIndex using libavcodec from that new beta6 be worthwhile ?

Not until the regressions for random access are fixed.

I've made some changes to improve audio delay detection and to properly detect and demux the new audio on BD, i.e., DTS Master Audio, TrueHD, EAC3. I would appreciate testing of this DGAVCIndex build:

http://neuron2.net/misc/dgavcindex108test.zip

Note that I ignore DTS Express audio because I cannot find anything that will play it, and it is never used for the main audio tracks.

I will port this to the NV tools when it is stabilized.

DTS express can be decoded by nero dts decoder. eac3to uses it to decode such tracks.

Version 1.0.8

* Added support for the new audio types found on BluRay disks.

* Improved the audio delay calculation.

* Removed the Treat I as IDR option as it is now always enabled.

Hi!

I have a problem concerning my Canon HF100 AVCHD camcorder.

I can set it to 24p recording, but too bad, it puts the 24p stream somehow into a 29,97 fps stream. There is no good way to retrieve the original frames, at least no that I know of.

Here are some details on this:
http://forum.corecodec.com/viewtopic...3&p=6947#p6793
http://forum.corecodec.com/viewtopic.php?t=817.0#p5007

Is there a way to sole this problem with DGAVCDec(NV) and AVISynth?

Best regards
