Hello, i quoted you on a random post to "ping you", i was wondering, can you see a reason why i cannot encode/shrink the BL only and then try to use -mode2 with your tool? It goes to 100% but i get no prompt like "enter to finish", and when i later try to mp4muxer it all together, it just stands there for hours.
Abit niche scenario, just wondered if you have an idea.
Cheers for amazing work
Hi, are you using the 0.0.4 ALFA version of my program?
If not, you can download it from my original post (
HERE).
I also invite you to read "Instructions and considerations".
thank you, i was not using 0.0.4 ALFA i will try that, the AUs are the same on BL and EL, and as i was typing this, it seems to work with 0.0.4!

i have lyp-sync problems with profile 7 with the movie escapre from new york. whats the solution? profile 4? (LG C9 internal)
i have now used the tool of grencola and the problem is gone. but if i first demux te files and convert to mp4, i get lyp-sync issue...

You are probably demuxing the AC3 track with Atmos, which will cause audio issues. Grencola's tool converts the Atmos AC3 track into a regular AC3.

i have that already done with eac334

after i extensively tested my M9702 DV vs DV profile 7 mp4, i saw there was no difference. first i thought there was a difference but that was a placebo effect i think. now i sold my unit. it was wasted money to keep it only for DV.

Odd results with War of the Worlds MKV and Grencola's tool. I can produce the MP4, it plays on my E6 and triggers DV, but it's half the size it should be and it's obviously missing something as very stuttery. Is there something I should have done that I missed?
I've also tried MP4 muxer profile 7 (profile 4 fails to build) and , and bl_el_rpu_builder in mode 1 and 2 with TSmux4.06 and I can't get anything to work. The enhancement layer is FEL if that makes a difference.
It would be great to have a FAQ along the lines of - if your el from media info is A (MEL/FEL, max luminance or whatever parameters are important) - do B (MP4mux, Grencola or bl_el_rpu_builder+TSMux) with the associated arguments like profile/mode and program builds if it's important (like TSmux4.06 and MP464bit). Probably too complicated because of the permutations but there doesn't seem to be one method that just seems to work. I've got lucky a few times but other times it takes hours of attempts. Still feels like great progress though and it's a real achievement so far.

There really aren't that many different permutations as it largely depends on your playback device. For LG Internal players, demux from decrypted backup (eac3to/ffmpeg) and mux using mp4muxer. Keep the BL and EL tracks separate and use the ac3 core of the truehd audio track. For the 2019 Shield, use the newest version of makemkv or yusecope's tool to merge the BL/EL tracks and mux with tsmuxer.
If you are making mp4s for your E6, you really have no need to go near mkvs, tsmuxer (unless you're using it to demux), or yusecope's tool.

So I made some color comparison tests with my HDfury Vertex on the Shield and the Sony x700 which accurately play DV.
Using the Vertex scaler, I removed the BT2020 flag from the RGB 8BIT Dolby vision signal and bingo!! the red push is gone.
No doubt in my mind this is the problem.
Shield RGB 8 BIT VERTEX FIX VS Shield RGB 8bit BT2020 DEFAULT mode

Nice comparisons! have you been able to do any additional comparisons with the shield+vertex vs x700 on FEL titles?

No, but I will now that I can get accurate colors with the Shield.

fingers crossed for incidental FEL support on the Shield

Very nice work! BTW, do you have a chromecast ultra to try the same thing on? It also triggers BT2020 on my E6 when outputting DV.

Maybe I missed it so apologies for being lazy and not searching right now, but what did you do on the vertex to remove the bt2020 flag? I'd like to try that with my integral 2. Thanks!!

No, I don't own a Chromecast Ultra.

in the scaler tab, you select ''RGB FULL'' for colorspace and ''follow'' for deep color.

Awesome, thanks. Will try that when I get a free minute.
EDIT: Brilliant! I just tried it out on a few videos, and it seems to work. This makes the shield usable for DV until they provide a proper fix.
