Occasional jerky/choppy playback

Well thats easy. Can we follow these steps or are other/extra steps needed: http://forum.zidoo.tv/index.php?threads/how-to-create-a-debug-log-rtd-1619bpd-players.96242/

 

What are your full settings?

Mine are:

HDMI cable: Original cable in box
Connection: Directly connected to HDMI 2 port of Samsung TV

Playback/Automatic frame rate/Frame rate mode: Match frame rate and resolution
Playback/Automatic frame rate/Frame rate pause: No Pause

Display/Resolution: Lock resolution (3840x2160p 60Hz) toggled on
Display/Resolution: Auto (3840x2160p 60Hz)
Display/Color Settings/4K 50~60Hz: Priority YUV420 12BIT
Display/Color Settings/4K 23~30Hz: Priority YUV444 12BIT
Display/Color Settings/Non-4K: Priority YUV444 12BIT
Display/Color Settings/Deep Colour compatibility mode: Open
Display/Color Settings/HDMI Signal format: Enhanced format
Display/HDR: Mapping HDR10

Audio/HDMI Audio: RAW
Audio/SPDIF audio: OFF
Audio/Downmix HD Audio output: Toggled OFF

 

I have that every tenth start or after pausing. I wrote that 2 weeks ago in the beta chat.
some seconds back and it's gone. impossible to reproduce for me. what I can say is I have it also on very small files / qualities, I'm currently looking into old star trek episodes, worst quality ever

with my set up here I can def rule out network / bandwidth issues, receiver or TV issues or the temperature topic.

of course match frame rate is always on.

 

Had the issue this evening watching a TV ep. Just skipped back a few seconds and all OK.

 

Hi Guys
just let you know
I think there is a bug in the system and i just managed to sort out my framerate issue (maybe temporary). I did not have a correct framerate all this time.
All i did
Factory reset after that turned on HDCP and select 3840 x 2160 @ 24hz in the android settings then turned on the developer mode and just selected the framerate in zidoo settings. This setting really upscaled 1080P for me first time since i bought zidoo.
Finally experience a smooth playback after months of buying Z2600. Now it does not drop any framrate for me.
I think Zidoo has some conflict with android settings may be cause by some bug .

 

HDMI cable: self bought one
Connection: connected to receiver, receiver connected to tv

Tv doesn't support dolby vision, only hdr10 and hdr10 plus

 

Yes absolutely.

The thing to remember about a debug log is it's hugely verbose set of files so we need it as tight as possible.

The best debug logs are:

1. Start Debugger
2. Immediately reproduce issue
3. Immediately stop debugger

If the issue doesn't manifest until sometime later, we need a timestamp to see the right area.

 

I checked some 1080p mkvs using direct on my Panasonic L1500Z OLEd vs the X9Z Pro VS10 for upscaling etc and definitely felt the Z9X with vs10 was better

Thats my setup , and getting no noticable stutter jerky choppy playback on anything

How many ppl getting the choppy etc issues used the Wizard to set up box ?

Someone on main .65 f/w thread had issues using that till they reset box and entered it all manually (if i read it right )

 

So, as crazy as this sounds i have to say that the framedrop bug has been mostly eliminated in my tests so far by raising the Zidoo 1cm.

I want to reiterate that my zidoo never felt hot or even warm to the touch...ever. HOWEVER, since raising it one centimeter using some lego pieces, i have watched Fellowship of the ring 3h48 minutes and another 2 hour movie and i haven't had the Framedrop happen ONCE. This is the first time after 3 months that i have been able to watch a movie without this issue.

I don't know what kind of chinese black magic is this, but could the people who experience the bug on every movie like me, try this little trick as well? Just raise your box with something and see the results.
I will leave mine like this and see if the issue has completely disappeared or it has just reduced in frequency.

The idea of raising the box is not mine, i picked it up from another user (can't find his post now) that said that he raised the zidoo and didn't have the bug.

Edit: nope bug appeared on 4K hdr atmos "Risen" on the 34 minute mark. Raising box does not eliminate the bug.

 

Quick note - if you set your resolution to 3840x230 23Hz you'll reduce your HDMI resyncs dramatically since most content is 23 not 24Hz.

Wizard? LOL. No, never

 

i know thats the logic Mark ,but honest im not getting any chop stutter etc ,hence im wondering if 24 rather than 23 (since most stuff is 23.976) is why thats happening ,hence why i posted above
seen one person post they changed from 23 to 24 and not seeing it now

 

It's really weird, we have just watched 2 x 45 minutes in a row, I couldn't see a single stutter. But sometimes it will be several in 45 minutes (series, simple DD+ audio tracks). Of course this makes it very difficult to diagnose.

 

That's the problem.

This issue may not manifest for days at a time.

 

Ok - interesting - if you see it again with frame rate set to 24, can you let me know?

Sometimes my frame rate is set to Auto, sometimes to 23, depending what I've been doing.

I've not seen it for a few days now - infuriating.

 

Its unbelievable....since I started to enable debug log I didn't experience it even once...grrr
Had mine at 23 as well. Changed to 60 and see if it changes anything.

 

Great news folks!!

@Sledgehamma has managed to catch this in a debug log so we've sent this to the devs

 

That very good news.
Any info on the video file played. Resolution, audio format, etc?

 

1080p VC-1 at 23.976 with DD 5.1 (BD remux).

 

Thanks for the info and that you could catch it.

 

I wonder if this will now delay the firmware that was due this week so they try and incorporate a fix.
