[RESOLVED] No Index

Post by Sharc » Fri Oct 25, 2019 11:20 am

I have a source which DGDecNV decodes, demuxes and plays correctly, but fails to create the full index.
The .dgi is just:

Code: Select all

DGAVCIndexFileNV22 DGIndexNV 2053.0.0.190 X32
C:\Program Files Video\DGDecNV\x32 Binaries\

D:\Temp\mer.ts 331482164

DISP 0,1920,0,1080 
FPS 60000 / 1001

Is something odd with the file? A sample is uploaded here (sorry it is 300MB, I could not trim it to less)

I downloaded your file and got the same results with an older version
Tried remuxing with TsMuxer, and that error-ed out, could not figure out video codec stream
Tried remuxing with MKVToolNix and it could not identify the video within the .ts container
I would say that at least your sample is corrupt
MediaInfo does recognize it though

DGIndexNV was not accepting profile_idc = 244 as valid. I have fixed that and everything works fine after that. Fix will be in the next slipstream. Thank you for pointing this out, Sharc.

Probably the other apps that fail with this stream also do not handle profile_idc = 244. 244 stands for High 4:4:4 Predictive, however, that profile also allows for 4:2:0. Perhaps this is the reason it is rejected by other apps, i.e., lack of 4:4:4 support in NVDEC for AVC. In the linked stream we have a High 4:4:4 Predictive profile, but the colorimetry is 4:2:0.

I'm curious to know where this stream came from. NVENC?

AFAIK the original "meridian" file is from here (scroll down to the bottom).
https://media.xiph.org/video/derf/

A converted HD .mp4 snippet for encoder and metric testing purpose was made available here, see 4th paragraph.
https://forum.videohelp.com/threads/394 ... ost2562157

I wrapped it into a .ts container for trimming by means of DGDecNV, and reporting the indexing issue.

Netflix Meridian. Sneaker converted a sample to 1920x1080 8bit 4:2:0 from the 300GB file for testing

Do we know what sneaker used to convert to HD and what was the command line? I am trying to determine how profile 244 came about. Also, the file in your first link is not 300GB; it says 96GB.

OK, but was profile 244 explicitly requested on the command line?

No idea. I didn't find a post of his commandline.
