DTS-HD MA 7.1 100% processors and jerky picture


#1

Hi All

I have a file 1080p DTS-HD MA 7.1 x264.mkv. The sound plays OK but the video is really jerky. I thought VERO 4K can handle everything and I am hoping it’s just some of my default settings on it are wrong. It’s connected via HDMI to my Pioneer amp which can handle DTS-HD and I have sound set on Vero as passthrough. However it still shows on my amp as PCM and not DTS-HD. Also while playing all processor cores on the Vero go to 98%-100% so clearly it’s struggling.

I had another file with DTS-HD MA 7.1 and it plays OK. That’s the only file which is almost unwatchable.

Also it must be something with settings but recently all files (no matter what audio TrueHD, DTS, DTS-HD they all show on amp as PCM!

Is it possible that something is wrong with Vero itself? I lost front blue led light as well recently (the one that shows the Vero is on) so maybe something is wrong.

Thanks,

Hi,

Its a 10 bit x264, The GPU can’t decode it; so its falling back to the cpu.

Thanks Tom.


#3

That’s a very strange encode for a modern film.
Hi10 has been deprecated for some time, and is usually exclusive to the anime scene.


#4

Thank you guys for this. Can I easily encode it to 8bit so it will play OK?

What about having PCM all the time no matter what audio it’s playing? Any thoughts?

Thanks in advance again.


#5

Need to see a debug log to advise on that.
See https://osmc.tv/wiki/general/how-to-submit-a-useful-support-request/.

Yes – transcoding to 8-bit will do the trick. Hi10 isn’t really a specification that exists outside of the anime communiy.

Why does it exist in the anime community. Does HDR use 10 bit? What 10 bits are we talking about? 10 bit color? I am asking because on some occasions a friend of mine has given me some files and I do get high CPU usage and jerky video on my Vero 4K. However this has never been a problem with bluray rips.

What if I start buying blurays from some animes, how does this affect me or can affect me?


#7

10 bits refers to color. Apparently the reason why anime uses it is because it compresses well with little quality loss (for anime, not for other sources). You will not find it on real bluray releases.


#8

Blu-ray spec is 10-bit HEVC for 4K content
Hi10 (h264) is not a commercial standard; so real world content won’t cause you a problem as you’ve noticed.

Anime on Blu-ray will be in spec and therefore not present a problem.

Just swapped my Vero 4k for my old Popcorn 110 (so same HDMI, same external HDD, same input in the receiver and all movies play with according symbol on the receiver’ s display (Dolby Digital, DTS, DTS-HD Master and so on) so no PCM at all. So it does look like something is wrong with my Hero as it had all the symbols before. Now only PCM no matter what track it plays. And like I’ve said no stand by blue led on the front anymore.

So why should I do? The other file I understand the problem was 10bit colour costing as other dts-hd files are playing OK. But not the sound for all the tracks is a problem.

Thanks.


#10

Well did you see this post?


#11

Oohhh yeah sorry… did that already but not sure if it went OK. The address it gave me at the end is:

Please let me know if the logs are there?

#12

16 days with no reply. So what I should do now? Is there something wrong with my Vero? As per my post my reciever is not picking up anymore any decoding types (DTS, True HD, DTS-HD Master and just showing PCM for all type of files, and no blue standBy/On light on the front).

Can you see something from the logs? Does it have to be replaced?

Thanks again for all the help.

Radek


#13

I can see <usedisplayasclock>true</usedisplayasclock> in your logs…

Please disable “Sync playback to display” under Settings/Player/Videos.


#14

Indeed. That should resolve the issue


#15

Thank you guys.

But there is still something wrong with it. The mentioned change did the trick but only for the none-HD formats! I see DTS and Dolby on my Reciever hovewer any TrueHD and DTS-HD MA doesn’y play at all… No sound coming from the Vero. Switching to my old Popcorn plays is all fine so all is good on the reciever’s end. Everything on Vero is set as Passthrough.

And still no LED light (small cross on the front of the unit) so clearly something went off there.

Issue with the 10bit file with DTS-HD MA audio I put to rest. I understand it’s the specific codec issue so I have no problems with that. As long as I know what exactly is wrong, I’m fine with that.

Please help.

Thanks again

Radek

Hi,

What do you see on the Pioneer amp during playback when you hear no sound?
A fresh log (with debugging) after making the changes @Chillbo suggested would be helpful


#17

On it… Will post it today… On the amp nothing changes. It’s just showing Stereo as before pressing the play button.

Radek


#18

OK, so here we go… latest logs. After enabling it I played ona DTS file (works OK) and one DTS-HD file which used to work, straight after - (no sound, nothing on the recievr’s display.)

Thanks,

#19

Any idea what’s going on?

Much appreciated. it was serving me really well but these days I spend more time investigating and reearching what’s wrong with it than use it really.

It would be good to have it beck to “set and forget” mode.
