Frame drop every ~34 seconds with himediaplayer

[eruo1]

I experienced frame drop only when using 1.0.5 Custom software . No frame drop in the official 1.0.5 firmware without the  patch.

It's a weird bug to see now. There have been many Q5/Q10 Pro sold and a huge amount of testing done. It can't be a general problem experienced by all users.

Anyway, I've reported it to HiMedia together with samples. They will be able to test it more thoroughly.

In 60Hz mode you wouldn't see them.

So say I don't see drops because I use 1080p/60Hz as my Display setting?

Yes. It appears to be caused by 23.976fps video being output at 24.000hz rather than 23.976hz when in 24p mode (24p mode is actually 23.976hz or 24hz output depending on input).

If you're in 60Hz mode then everything gets output at 60Hz.

Do we know why do we have a frame jump/shutter at all? I mean if it's a rounding error between 23.976 and 24 we should get the same framejump with 60 as well because we have the same rounding problem there as well.

This is where it gets complicated!

HiMedia are aware of this problem and will fix it.

In the meantime, installing the pcristi/looun autoswitch patch fixes the problem completely (as well as adding auto framerate switching output matching input frame rate for all fraemrates): http://www.futeko.com/newforum/index.php?topic=1043.0

It doesn't fix the problem for me. I've tested:
1. Firmware 1.0.3 with and without patch, 24p setting ON and OFF, Imprex Engine N and OFF.
2. Firmware 1.0.5 with and without patch, 24p setting ON and OFF, Imprex Engine N and OFF.

Jump occurs in any cases.

Hi

me too have same issue. I notice with mkv movie 1080p (or less) 23.976 fps.
Also it seems (when it happens) go backward by a frame then forward by a frame. The result is a strange effect as "go-back-go frame" .
Q5 Pro with Firmware 1.0.5 and no patch at all.

I'll try with test suggested by futeko.
However it's singular when it appears. it seems appears every 30 sec (more or less), that match with other collegues.

Also (i have same issue with different old mediaplayer "xtreamer"), when it tend to play a 23.976 fps source by 24 fps output, mediaplayer must drop a frame every 42 sec (not every 34-26-60 sec).

But... how can it happens with a new/advanced media player as himedia claims.

Hope in a quick solution

After more pendulum watching I agree.

So only kodi add-on with Kodi dvdplayer works as it should.

I have fed this back to Himedia and am pushing them as hard as I can for a quick fix.

@Futeko
Do you mean in your last post, that kodi with his own player and the "Kodi ADDON- Frequency Switcher" can handle 23.976 fps without microstutters?
Because i have Kodi 16.1 with "Kodi ADDON- Frequency Switcher 3.3.3" and i have stutters with 23.976 files every 50sec (more or less). Wrapper is off.
Perhaps i make something wrong in Kodi?

Thank you Futeko

Yes. At least with the test samples mentioned in this thread playback appears perfect with dvdplayer and the kodi switcher addon. I've just watched them again and no stutter 9perceptable to me at least), not at 26 seconds or 50. The stutter problem with himediaplayer doesn't appear to be Q5/Q10 Pro hardware, which has HDMI output set to 23.976Hz, it's the himediaplayer app.

Can you point me to a testing sample (e.g. one of the Kodi wiki sample files) where you see stuttering every 50 seconds with Kodi dvdplayer + Kodi autoswitch add-on?

Microstutter at 54sec, 104sec, 154sec and so on.
