1- Yes
2- Yes, the Ugoos is more accurate than the ATV and more practical than the x800m2.
3- 100% stable so far and already watched over 10 movies (FEL P7 & P8)

Big props to @cpm00 for figuring out the fake tv-led bug.
Thanks, just a final additional for DV to the CE team's efforts - the player continues to improve on this fully open source (apart from DoVi library for obvious reasons) platform it's a great elegant solution for the home enthusiast, without the worry of a bloated Android OS and whatever else would be lurking in the corners on such a platform.

I imagine the issue will eventually be twigged by AMLogic and more devices / solutions will benefit overtime, but for now this is the one.

If you still measure a tiny diff in brightness, when you get a spare moment can you give the following a try:

Code: Select all

echo 13 > /sys/module/amdolby_vision/parameters/dolby_vision_flags
It setups the dv engine on the box to follow the sink (TV) luminance values rather than some basic hard coded values of 0.005-4000 nits, I thought his only effected LLDV, but from some comments from quietvoid it may have effect on the FEL 12 bit composition as well.

Personally I cannot see a diff but not got the setup to measure that low level brightness.

to revert can just reboot - or issue this command:

Code: Select all

echo 5 > /sys/module/amdolby_vision/parameters/dolby_vision_flags
thanks.

Sure I can have a look this weekend when I also compare CMV4.0 (and CE-21) but honestly, right now I'm 100% satisfied with the current build ( 20.5) I did all my tests and I'm more in my ''enjoying movies'' phase :)

Been a long time lurker in this thread, just wanted to say thank you to RESET_9999 and all the other folks in here for the helpful information over the years! Have a AM6B+ on the way now and looking forwarding to testing it out with some DV mkvs!

Hi m8, this is a ssh command, right?

Also can you look into a fix for TrueHD/Atmos to PCM conversion on coreelec. Native Android-kodi works fine but on coreelec only upto AC3 5.1 is converted to PCM.

Thanks.

Yes those are commands to issue on a ssh connection to the box, just short hand to change the values in those sys parameter files.

Was just trying some other things out and turns out the 2nd command will not revert fully - will need to reboot to revert fully.

Would not know where to look on the PCM conversion, could ask the CE guys on their forum, I personally use passthrough.

line 59
:: choose the mp4muxer version (OLD or NEW default = NEW) OLD works on (2018) LG TVS but Itunes P8 hybrid wont work if you dont fix the bitstream framerate first. And when input has lossless audio or subs, the old mp4box needed will not properly set the BL compatibility ID which doesnt seem to cause issues though.
set mp4_version=NEW

Thanks RESET_9999, tried that but this old lg c6 is not having it, can you do DV fel mp4 dl (with good image/video highlights that might work on c6 internal ) and drop me a link, trying to compare to minix u22 xj max CE as I think it still using player-led? Of course when you are free, many thanks.

What’s the workflow to inject fixed P7 FEL RPU back into video without converting it to P8 (doing this for avatar the way of water)
