This is not exactly a bug but I have asked HiMedia to look at implementing it.

How many other people would like this feature added?

[Karl]

Yes please
Thanks.

HiMedia are investigating. If it's possible to implement (which I think it is) then it will be.

with himediaplayer not work 29,970.
on remote control it's nice to be have also 23,976 ,24p selectable on "TV mode" button. 

it very nice to be have same option on kodi interna player, like amolgic rockchip script on SPMC:

Auto-framerate switching for Amlogic (Needs 666 on /sys/class/display/mode)
Auto-framerate switching for Rockchip (Needs 666 on /sys/class/display/display0.HDMI/mode)

himeda q5 is great player ( say from PCH A400 user ), with this option on kodi can be one of the best andorid player.

real 23,976 and auto-switch is the greater deficiency on andorid player.

i have a Q5 Quad which is a really great player. But i have every now an then a "little stutter" (every few minutes) when watchin 1080p23.97fps movies. the 24p option in the player menu is selected

so is this because the player can't display 23.97 correct? only with 24fps?

i watch my movies on a big projector screen in native 24p and i don't think it will be noticeable on a smaller tvs, especially when you have smoothscreen or anything like this with your tv enabled...

is there anything i can do to correct this problem?

from Hi3798M V100 Brief Data Sheet there isn't 23,976 support , but i have done lot of video and test without stuttering or drop frame.

try this test

i think everything looks fine with the 1080p23.97 bar maybe the 2minutes are to short to see it. but when there is the 24fps bug, the stutter should be there every 42 seconds, so it must be something else. or it hast to do with high bitrate (eg. blu ray iso) i think the stutter is there every 3-5 minutes... and it occurs, whether its from usb hard disk or network streaming. maybe it has to do with a buffer cache or something like this...

but most of the time i notice it only if i look for it

but the 720p59fps doesn't work perfekt

right:  video 23,976 -> hdmi out 24,000 is 0,024fps --> 1 sec/ 0,024fps = 41,67 secs.

yes i havo also problem with  29,970, lot of dropframe.

it's helpful test with KODI dug  ( video 23,976 -> hdmi out 23,98 hz no shutter! ) ,but not work option "Adjust display refresh rate to match video" on it.

it's very nice modify Addon Frequency Switcher for himedia hardware.
i have try, but there isn't  "/sys/class/display/mode" himedia firmware.


Himediaplayer don't have dug i think.

looun, I just accidentally deleted your message and can't get it back. Sorry. Early morning..

there is same news? and i don't understand if  Hi3798 support 23,976 (playback without shutter )?
Thanks.

[rikioh]

...is this stuttering every few minutes something, which can be fixed with a newer firmware update?

From HiMedia:

23.987 still not supported. We pushed many times on HiSilicon company. But they still not give us exact date
