I’m having a problem playing the dolby vision files on an external hdd connected to lg oled c7 via usb. The video stutters heavily at certain parts. The hdr10 version runs fine though. Movies tested are Jigsaw (2017), Jurassic World Fallen Kingdom (2018) and Overlord (2018). I’m pretty sure the bandwidth of usb 3.0 on the c7 should be more than enough for this right? Not sure what causes the stuttering.
were you getting framerate errors during the creation of your mp4s? if it's a remux sometimes they need to be repaired with mkvtoolnix. I haven't seen this happen with m2ts files.
No I got no errors (I used your program. Does it notify framerate error if there is any?). And I used m2ts files.

My TV is a Roku TV and Plex doesn't natively support the DVHE but will play if you force it to. When trying to seek forward or backward though always results in the file starting from the beginning no matter where your at. I haven't tried using the USB media player.
Ah I see. Yea every model has their own unique struggles. The usb media player may play better than forcing unsupported media in plex. you might just be out of luck though unless you grab an x700 or something similar to play them on

Sorry to hijack your post but is the x700 the "best" non-Oppo player to play full DV rips currently? Some of the reviews I see for it are a bit worrisome. I've started ripping but actually don't have a 4k tv yet but plan to soon. Will need a player if I can't play DV via htpc.

My X700 is stable. Wish it had gigabit ethernet, but other than that it works. You also have to manually enabled DV in the menu which can be annoying.

the x700 is just a quick cheap fix to play dv mp4s. it won't play full rips in dv, only hdr10. Oppo and its clones are the only external devices that will play full rips in dv properly.

enabling the dv option it has just essentially forces fake dv from the base hdr10 layer without seeing the actual dv Metadata. the tv might say dv, but check the player info - it will only be hdr10. I thought the same thing at first too. (see pg. 9)

That is lame. I would want the full rip quality. Oppo or clone it is I guess. Thanks for the feedback.

Hi folks !

Yesterday night i tried my first DV movie on my new LG C8 and it worked like a charm ! Im very impressed by the quality of DV and the TV in general. Everything works great, just some little issues, a few seconds of video lag (due to usb low rpm hd maybe ?) and just 2 seconds of some visible artifacts. Maybe due to some errors during encoding, i dont know. Btw nothing much at all, the movie was very enjoyable. Thanks again !

Hi. Which movie did you watch and what kind of artifacts did you notice? As for the lag I discovered that it could be very likely caused by the hard drive itself. I once encountered terrible lag using on hdd but when I changed it to another it was fine.

I watched Mortal Engines. I create the .mp4 from .iso
Artifacts like a large green strip in the middle of the screen for a few seconds. Yeah, tonight i will use another HD (7200rpm) and i will see.

I have LG C7 and I also have these artifacts in some movies. It is not because of DV or a HDD, but because of the player in TV. It cause artifacts also on the remuxes or on the m2ts files from ISO. It's too bad that LG didn't fix it on new model (also someone should try it on C7). I fixed this by buying Sony X700 where it works fine.
I just have an issue there with DV. Sometimes, when there is a change of the shot in the movie, the screen flashes for a 1 frame. If someone know how to fix this, it would be awesome. I have this problem just with DV.

I figured out what was going on, because I have so many 4k blu-rays (over 300) storing these directly ripped from the disc is unreasonable. The total size would be roughly over 15TB, Yikes!. So I have been re-encoding the 4K track and leaving the DV track the same, since I can't really do anything with this track. The problem is the mp4muxer only likes the re-ecoded file if I pass it through ffmpeg with a copy filter -bsf hevc_mp4toannexb. I even tried muxing the encoded track only using this: mp4muxer --input-file video.265 -o video.mp4. even this results in the mp4 being unseekable. I'm not sure what do with handbrake to change settings that would result in an encoded file that would work. I'm currently trying samples to see if I can come up with a solutions.

If any one else out there has the same problem and might have a solution, I'm up for trying it.

Thanks

Found some more interesting info that might help.

I did find out that seeking is working but it is very cpu intensive and on my 6 core 12 thread machine, it maxes the cpus to 100% and takes over a minute for the seek to happen. The TV is probably giving up after a short period and just starts over from the beginning.

I tried doing some research around 10bit 265 and mp4's and it turns out that mp4muxer does not write the file correctly that would build a resulted file that is seeable under a normal conditions.

For clarification here are the commands I ran to build comparison files, NOTE: these are all without dv files.

Code: Select all

mp4muxer -i video.265 -i audio.ac3 -o temp_mp4muxer.mp4

Code: Select all

mp4box -add video.265 -add audio.ac3 -new temp_mp4box.mp4

Code: Select all

ffmpeg -i video.265 -i audio.ac3 -c copy -map 0:0 -map 1:0 temp_ffmpeg.mp4
ffmpeg and mp4box produce a seekable file whereas mp4muxer does not.

I would also like to note that all three of these command produce different byte codes.

I just tried few movies more and i can't play them well. "The gladiator" and "A queit place" stutter like hell ! (i make the mux with the latest grencola app). Maybe later i try to mux with the instructions in page 1 (Mortal Engines worked with that).
