First, config : NVIDIA GTX 1060 3GB Driver 461.40 Windows 7 x64 I've encounter an unexpected issue on my process. The odd thing is the sudden part of it, as it's something i'm doing now for years without any issue, and suddenly, something happens when doing the same thing i've done for years. For no...

Ouua ! Thanks for all these improvements.

BTW, I'm a bit confused about modulo. What is 256 mod 0?

It is not what they call a singularity in quantum mechanical...?

If i understand properly. You have an m2ts file, you demux audio and video and have, for exemple, an .264 video file, and .ac3 audio file. You want then to work with the .264 video file instead, and not the .m2ts file anymore. Am i correct ? If i am, correct, one possibility, but i don't know if it'...

I have no idea, i want to experiment several things, when you see fig.37 of BT.2390, it seems that white point scaling is a possibilty, so that's why i'm trying to figure out what is the formula. BT.709 define a fixed white point, in HDR, there is a white point information, so maybe it can be useful...

Very nice result (and "fun" movie also). I've been looking out for formula of how tweaking white point : converting (R0,G0,B0) with white point at (x0,y0) to (R1,G1,B1) with a white point at (x1,y1), but without success for now... :? As you're talking about it, do you know where i can find it, or is...

i would like a 10/12/16 bit HDR->SDR... :D More seriously, i also agree with gonca on the part "you choose" if finaly one feature request is not more asked than another. My request was more for curiosity to see what it gives, than a real immediate needs. Also, i'm sorry, it seems i've badly asked my...

HDR -> SDR... :D You're talking about a specific tone maping, does it mean you've made tests with several and thought this one is "the best" ? Are you interested (even if you're not doing this feature right now) in an 50GB HDR movie, and in a 25GB file of the exact same movie in SDR ? It seems also ...

Ok, got a very interesting answer and information about HDR. I had no idea it was in a such mess state...
Seeing this, i gave up the idea of trying to do an HDR to SDR convertion.

Thanks. Very interesting result, this experiment confirm my thoughts, that the display device needs these metadata to properly display HDR content. I'm still having trouble with what kolak said that device use high complex method algorith just to display HDR. And for now, i can't get rid of the idea...

Otherwise, drives appart, any comment on my post @gonca Is it possible for you to do a little experiment for me ? In the first page of this thread, it seems that you're doing your own H265 HDR encode. If possible, could you trim 20s of a video, and make 2 encodes of it : - With the proper mastering ...

Usualy, i use AnyDVD for all my BR. But, for this title, i've encounter an issue for the 1rst time, AnyDVD wanted to connect to its database. As my PC video is totaly offline, i had to found something else. Finaly, makemkv did the job. I didn't create an mkv, but just save the disc. Didn't realize t...

Going back to HDR... ;) I've posted on another forum a long post, about my still struggling issues and thoughts i have about HDR. If you have time to read it, and eventually share your thoughts also here. It's of course absolutely not related to the fact that yesterday i got in my hand my first UHD ...

I didn't know you can open mpls in DGIndexNV... So, as i said, you can beat me...

Ah... you replied while i was editing my post...

For what i know : I don't think the 1) 2)... are relevant to anything, it's just an enumeration, and i don't think you can use them. I don't think eac3to output directly raw PID values (and i don't think it can), it translate them into the information displayed. For the workflow, i let the others de...

I don't know if this will answer your question :
Personnaly, i just run "eac3to > file.txt". But you have to run it on the root of the Blu-Ray.
Then, in the text file, you'll see langage informations. It probably take them from the mpls file.

I'm afraid It requires to know the specs of mpls, and maybe only those who have acces to Blu-Ray specs may have it...

Personnaly to have these informations i run eac3to in the full Blu-Ray root directory (after rip, of course... ).

I've asked this question on a well know forum, but i thought i may ask also here : From what i've understood, UHD BR can be HDR, but it's not mandatory. 4k/UHD doesn't always mean content is HDR, these are two different things. So my question is (even if UHD BR not HDR may be very unlikey), i bought...

Nice work.
And reading this i just discover gMKVExtractGUI...

It would be useful to have the correct fonts demuxed according to selected ass sub(s). Ouch ! Don't you think it's begining to be a little too much difficult ? Because when you mux an mkv, nothing technicaly links the fonts to the ass file (except maybe when the font are included within the ass fil...

No big deal, it was just in case it could be of use. I don't realy understand the fact that you don't (for now) work with uncompressed PGS. Now that you've included zlib, didn't you "just" check if the stream (whatever stream it could be : video, audio, subtitles and any kind/version of each) is com...

For zlib, i personnaly use it for writing PNG, but directly put the C files in the project, not a dll. I'll tell you how i've done it, in case you would be interested. Go to zlib official site, get the zlib1211.zip source files. The needed files (to add in your project) are : adler32.c compress.c cr...

Probably not. The two deleted probably existed only for a short time, and i've seen them during this short time. At least my memory is still working properly... for now...
Thanks for all your work.

Yes, I need to honor whether the streams are compressed or not, it's signaled in the MKV obviously. Do you know by any chance if it's only zlib, or if there is also others compression format that can legaly be used ? The fact that i remember (properly or not...?) once a gui where you can choose com...
