Dolby Vision now possible through MP4 Mux.

Just bought an X800m2 ...

- High bitrate movie via 5GHZ wifi works flawlessly (tested Dead Heat 92mbps avg bitrate and peak over 100mbps all the time)
- This player is not affected by the tsmuxer dual-track dual-layer bug, no green/purple screen issue.. WOW!!!
- This player auto-switch from DV, HDR10, and SDR with TS/M2TS files WOW!!! (only via the network)
- FF / RW works for long movies. great!!
- cropped DV content displayed with grey letterbox
- DD+ with an empty core doesn't play but strangely DD+ Atmos works perfectly.

hopefully, it's as stable as the x700 for DV playback, I will watch some movies this weekend.




Dead Heat bitrate:

-how do you play high bitrate movies over wifi? Would like to stream the files directly from my pc instead of copying over to external hard drive every time.
-auto-switch between dv, hdr10, sdr doesn't work via usb?

Just bought an X800m2 ...

- Single Track, Dual Layer FEL working?
- Fast Forwarding with just TS file?

I guess Single Track Dual Layer FEL is not working from MKV right?

Thanks

1- Single Track, Dual Layer FEL working?
2- Fast Forwarding with just TS file?

3-I guess Single Track Dual Layer FEL is not working from MKV right?

Thanks

1- yes but just like the x700 and oppo. Some random ST-DL wont play while all the DT-DL files will play.
2- I don't know, I only watch DV TS files. The x700 has a bug when movies are very long, you cant FF/RW. The x800m2 doesn't have this bug( at least with the 4h30 movie I tested).
3- right, existing bluray players will never support DV in an MKV container.

1- how do you play high bitrate movies over wifi? Would like to stream the files directly from my pc instead of copying over to external hard drive every time.

1- the x800m2 has a 5GHZ wifi chip so it's actually faster than the 100mbps ethernet port. I just watched Dead Heat 92mbps avg bitrate(streamed from my PC) and it didn't buffer one time. My router is in the same room as my player though: the 5ghz range is not as good as 2ghz.
2- nop it doesn't work via USB: only works via the network. Maybe the behavior is the same for the X700, I never used the network, thanks to the slow ethernet/wifi speed.

I can't recommend the x700 anymore when the x800m2 is a LOT superior. Actually better than the oppo too(I hate BD folders/iso storage) because there's no dual track dual-layer TS bug .
keep in mind that I watched hundreds of DV movies with my x700 without a single playback issue (except the known bugs) and watched only one movie with the x800m2 so maybe some other issue will come up.

How do you stream from your pc to the bluray player?

Too bad the x800 is not even sold in my country. Actually the x700 is the only 4k bluray player from a reputable brand sold in my country. The bluray player market is so dead here. Can't find any uhd physical disc either. I have to download 4k hdr films (either the full bmdv folder or remuxed mkv) from shady sites otherwise I won't be able to watch those films at all.

How do you stream from your pc to the bluray player?

my windows videos and music library (DLNA) just show up on my x800m2.
I use classic windows media player to create a playlist of recent movies I have to watch otherwise it can be a pain to find 1 movie out of 1000+
You can also make a windows SERVIIO server which is also detected by the player

Thank you very much for all the info and please do keep us up-to-date with any other issues or good experiences as you watch more. I'm very tempted now to get one and the only thing really holding me back is the thought of transcoding my MKVs back to M2TS!

[sickb]

Muxing, I hope.

[FubbAyH]

Muxing, I hope.

Oh yes, quite right

Can I ask (I promised I searched the thread first, but couldn't find an answer) does the X800M2 handle profile 8.1 DV well? I was looking through my collection to see if I could stomach remuxing the DV titles and noticed that I have more profile 8.1 hybrids than profile 7 rips at this point (thanks Disney!)

[RESET_9999]

does the X800M2 handle profile 8.1 DV well?

yes

[FubbAyH]

Awesome, thank you! I found a X800M2 in stock nearby so I'm gunna go buy it later and finally join the FEL club

transcoding my MKVs back to M2TS!

If all your DV movies are in MKV, you'll have a lot of work to do because you'll have to convert TrueHD to TrueHD+ac3 with eac3to (unless the tsmuxer devs add support soon).
Also, if your profile 7 files are single track dual layer MKV, you'll have(sometimes) to 1- demux the layers and 2- convert trueHD because some ST file gives a black screen.

If you have fast internet, it might be faster just to download the complete ISO and make a new TS.

[FubbAyH]

Thank you, I've just been figuring that out today. I've made a little script now to do most of the conversion and I'm only gunna convert my (~20) DV titles (and keep watching the HDR10 ones on AppleTV) so doesn't look like it'll be too bad. I'm certainly regretting stripping out those AC3 cores, though, now!

[FubbAyH]

Here's what my script looks like, btw, just in case anyone else is in the same position of needing to convert DV MKVs to M2TSs for X800M2 (or X700):

Code: Select all

mkvextract source.mkv tracks 0:stdl.hevc
dovi_tool demux stdl.hevc
# previous command produces BL.hevc and EL.hevc

# if the movie has TrueHD audio (almost all discs) then an AC3 core is required for hardware players to see it as a compliant stream
# the original TrueHD track from a disc will always have it, or:
mkvextract source.mkv tracks 1:source.thd
# a minimal core can be generated with:
#eac3to source.thd audio.thd+ac3 -downStereo -32
# or a decent-sounding core can be transcoded with:
eac3to source.thd audio.thd+ac3
# that runs at about 7.2x real-time, so ~17m for a 2h movie

# use tsMuxeR GUI to mux a M2TS file
# Output: M2TS muxing
# add
#  BL.hevc
#  EL.hevc
#  audio.thd+ac3
#  source.mkv
# set the language of the audio.thd+ac3 track
# uncheck the video stream from source.mkv, and its audio stream if using a transcoded one
# if movie has forced subs then note that in the filename by adding " {Forced Subs}" to remind yourself that you need to turn them on manually, and move the forced sub-only track that MakeMKV creates to be the first subtitle track

here's my script(based on FubbAyH, thanks) to demux ST-DL and convert TrueHD to TrueHd+ac3 (and more)

[FubbAyH]

this seems to take the same processing time as converting the core to regular 640kbps 5.1...
is there a way to generate an ac3 core without re-encoding like they are trying to do in tsmuxer? even if the core is silent, I don't mind as long as TrueHD works.

Yeah, I've been trying to figure out if that's possible too. My guess is that because the TrueHD is based on the AC3 core, when you add the core it needs to re-encode the TrueHD too to match? (which I'm presuming is why it takes a while) So maybe it's possible to create a core that doesn't need the TrueHD data to be re-encoded, but I don't know anywhere near enough about the details of AC3 or TrueHD to know

Thank you for your scripts too!
