Looks like from the article here,
https://www.xda-developers.com/xiaomi-t ... 1-support/, it sports an Amlogic SOC. Hopefully like some of the previous Amlogic devices, it'll still have the dual video decoders necessary for FEL playback.

Good news! There's been an update to TS-Muxer which now allows the importing of TrueHD tracks directly from MKVs!

If it is using the AMLOGIC S905Y4 as that article suggests, I found some specs that say that SOC can simultaneously decode 4 x 1080p60 streams, so
maybe the one 2160p23.976 stream plus one 1080p23.976 stream required for FEL DV isn't out of question. I would guess that the big problem would be software support, though? I haven't followed the Android player app scene, but are there any Android player apps can that can handle FEL on
any device? I'm guessing not otherwise we all would have bought that device, right?
I suppose the built-in player could have unofficial FEL support if there's an engineer at Xiaomi who is a DV enthusiast.

yes, and soon it will also work on the x700 because right now tsmuxer doesn't add an ac3 core which the x700(and bluray players) need to be able to play TrueHD.
really a time-saver...

Ah, forgive me. I hadn't yet tested it out with my Oppo before posting. I didn't realize it was missing the ac3 core.

Thanks, although I only tried out with one, but it the AVR didn't recognised it as TruHD, there were no sound playing back from Oppo. I used the 2022-01-26 version.
Does it work for you? If so, with which nightly exactly?

has anyone had this error with dovi tool?
Code: Select all
Error: Condition failed: `self.max_display_mastering_luminance <= MAX_PQ_LUMINANCE` (38528 vs 10000)
Did you use a JSON file to edit the L6 metadata in your dovi_tool workflow?
Something like:
"level6": {
"max_display_mastering_luminance": 4000,
"min_display_mastering_luminance": 50,
"max_content_light_level": 1272,
"max_frame_average_light_level": 823
}
If so, it looks like you (or something) set max_display_mastering_luminance to 38528 rather than the usual values of 1000 or 4000. The error is saying the max value is 10000.
If you're editing L6, dovi_tool needs all L6 values to be integers, not floating point values, so you need to multiply the typical min_display_mastering_luminance value of 0.0050 cd/m2 by 10000, so using the value 50 instead.
But you don't multiple the max_display_mastering_luminance. So if something set that to 38528, that would be a problem.

Single Track Dual Layer
Dual Track Dual Layer
Those are terms primarily for DoVi Profile 7, used with UHD BDs.
STDL is used in some formats, e.g., mkv files, where a single HEVC video track can contain the BL+EL+RPU (that is: the 2160p or 1080p Base Layer video substream + the 1080p Enhancement Layer video substream that may carry additional video data + the Reference Picture Unit (RPU) substream that holds the DoVi dynamic metadata).
DTDL is used in some formats, e.g., m2ts files on UHD BD, where the BL video stream is stored in one video track and the EL+RPU substreams are stored in a second EL video track.
MakeMKV can take in DTDL from UHD BD or mkv files, or STDL from mkv files, and output STDL mkv files.

Yep, I had this issue with Amores perros iTunes web-dl. typical apple , they often do stupid things like that.
original rpu:
Code: Select all
"Level6": {
"max_display_mastering_luminance": 23040,
"min_display_mastering_luminance": 50,
"max_content_light_level": 1033,
"max_frame_average_light_level": 272
}

Hey guys, many of the streaming versions contain e-ac-3+atmos, which doesn‘t exists on blu-rays. Blu-rays have usually a TrueHD Atmos and an E-AC-3 tracks. Unfortunately Truhd isn‘t supported by my tv, but e-ac3+atmos plays very well and sounds better that just e-ac3 or even dts-he master audio. Is there a way to take the atmos information from the TruHD Atmos track and embed ist into the e-ac-3, so we get the same as in streaming versions or even just downconvert truhd but keep the atmos?
My goal is to get from TrueHD Atrmos to E-AC-3 JOC (Dolby Digital Plus with Dolby Atmos)

you need DEE for that. The best you can get right now is e-AC3 1536kbps with ffmpeg.
