CX48 - Played via USB using the internal player:
DTDL_FEL_1: "This file cannot be recognised. Do you want to play the next file?"
DTDL_FEL_2: "This file cannot be recognised. Do you want to play the next file?"
DTDL_FEL_3: "This file cannot be recognised. Do you want to play the next file?"
DTDL_FEL_4: "This file cannot be recognised. Do you want to play the next file?"

On my LG C8, via DLNA, they all show the endless spinning wheel and never start playing back.
Same behavior as the latest mp4muxer when creating dual track mp4s.

On LG C7, all 4 files = spinning wheel and never start playing back.

In summary:
- All DTDL MP4 test files triggered DV for x700 - may or may not be buffering issues, files too small
- ..................................
Ok, we are getting closer to emulating the behavior of the latest version of mp4muxer: the new LGs do not recognize files, the "old" LGs recognize files but cannot play them, X700 recognizes and plays the files.

I thought you took inspiration from that code though. Maybe you could find a significant difference between 2018 and now's code.
It takes time (which I don't have
![Sad :(](./images/smilies/icon_sad.gif)
) and it would be like looking for a needle in a haystack
![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)
.
It would be much easier to evaluate the output products of the two versions instead.
I have compared two versions of Terminator - Dark Fate and to my surprise, they are identical. The only differences identified are related to the Bytes of "creation time" and "modification time" of the file as regards the atoms
mvhd (image),
tkhd and
mdhd. Insignificant differences and therefore the two files can be considered the same.
I'm sure you know how to use a hex editor and maybe you could try it too and maybe you're luckier than me.
Just compare the two files (only video, no audio): if you spot a significant difference I might try to modify the behavior of my tool to emulate it!

Zidoo Z9X .... panasonic z1000 oled ....all 4 played hdr pq only ...no stutters
Zidoo Z9X and panasonic z1000 cannot play DTDL files - it is normal to get only HDR.

Indeed! 8.8.1 triggers DV on all of my GAMMA profile 8 and profile 7 MKV files, the Alpha Muxed files and the original TSMuxer method. I just hope that I'm getting DV and not simply showing as triggered. As a result, I intend to use the GAMMA MKV method going forward.
Very impressive Yusesope!
In the end you succeeded...
At this point, update your previous post (regarding the results on the Shield 2019) and to be sure check again the DTDL mp4 files with the X700 following the instructions of the wise @RESET_9999

the x700 OSD will show ''Dolby Vision HDR'' for real DV and ''HDR'' only for fake DV.

Maybe in all these files we are just getting HDR10 with dynamic metadata.
HDR10 with dynamic metadata is HDR10+.
The only Android device capable of "playing" FEL files is the new Shield.
There remains the problem of the "red push".
However, the problem also occurs with MEL files.
MEL files (original or converted with my tool) play perfectly on the FireStick 4K.
I'm not an electrical engineer but Dolby would have no interest in building different chips for different devices! It is cheaper to distribute the same specifications to make the various manufacturers realize the same hardware decoder (FPGAs, SoCs, etc ...). What changes is the firmware implementation that must take into account the other characteristics of the device: CPU power, RAM quantity, etc ...
The FireStick 4K plays MEL files correctly, the Shield does not. The FireStick therefore has a better software implementation.
If you remember, the "red color problem" also plagued the DV profile 5 on the new Shield. The problem has been corrected with a software update.
The Fire Stick 4K cannot play FEL files due to hardware limitations (CPU, RAM, etc.)
stupid example: take a new nVidia RTX 3090 and use it on a system with an Intel i9-10900K and on a system with an older Pentium 4. The GPU is the same: will you have the same FPS in game? Will you be able to play a 4K video on both PCs?

Hi Yusesope, can you explain why you think FEL titles created with Gamma 004 don’t trigger DV on Zidoo Z9X regardless of which conversion to MEL or profile is used?
I don't know the device at all, so I don't have a clue ...
