QTV driver problem in core player

it seems that the driver is causing freezes in my X1 while playing and then stopping/pausing and resuming videos using core player
anybody else get the same problem?
any idea how to fix this?

I've not been using the QTV driver in coreplayer.
I've had the best results with the following:
1. Turning off the "TYTN 2 Driver mode" on the Qtv preferences page
2. Selecting "Direct draw" and "high quality" on the Video page.
3. selecting "RGB" as the overlay format on the Direct draw page.

I already hard reset and now it runs at normal speed, still not sure about the freezes problem, need more investigation and time...
but I'm curious as to what is the best config for X1?
Ben, u said u don't use qtv, then what do you use?
anybody else?

direct draw here

i did notice that my benchmark is better when i use Qtv instead of directdraw.

I watch Iron Man (800ish MB DivX) in bed on Sunday using Direct Draw and other than the gun firing scene it seemed to run pretty smoothly.

please, try to use coreplayer 1.2.5 diamond skinned edition.
this will work flawless on my x1. (touch-it hd firmware)

can u upload the cab?

I am facing the same issue too. This is my experience: Actually the X1 did not hang, only the screen hang. You can press the on/off button and you will hear the pop up window to confirm the shutdown. Just "guestimate" where the yes button is and press on the screen. It should shut down.

Using your settings, the video is playing back in slow motion!
Try mine:
Use QTv, set to medium quality, no zoom.

medium quality makes the picture looks bad.....
so we can conclude that core player isn't truly support X1 for now?

@nap007 same problem here, with qtv output.
DirectDraw @ medium quality works fine for me
a 700mb xvid,resolution somewhere round 640x400 played smoothly and
quality is still nice @medium

For me too qTV is the fastest.
qTv with unchecked Tytn II mode does not render any video.
DirectDraw with blitting is 10% slower.
DirectDraw without blitting does not zoom the picture.
All around it's slower 10-20% then TCPMP and my 2 years old Palm T5 ! Sure, it had only 320x480 resolution, but I really expected more in this area.
Only hope is CorePlayer will come with some better Xperia support soon.

here's my setting in Coreplayer that renders the video smooth
Video
- Video Output: QTv display
- Video Quality: High
- Smooth Zoom: Only for 50%
- Dither - Yes
Buffer

- Preload for audio: 64KB
- Microdrive mode: Yes
- Microdrive buffer size: 16000KB
- Microdrive starts at: 1472KB
Advance
Off: No backlight keepalive for video, Slow video memory, Less rotation tearing, High priority music playback, Override AVI timing based on audio, Use system volume, Capture all buttons, Keep screen on when playing audio
On: Prefer lookup tables over arithmetic, D-pad follow screen orientation, Prefer less buffering over framerate, Benchmark from current pos, Pause playback when making phone call, Unpause playback after call, Disable AVC deblocking filter

TyTN II driver mode - Yes

The Ultimate HD2 & coreplayer 1.3.6 setup, 3800kbps wvga (h264) no single frameskip.

The Ultimate HD2 & coreplayer 1.3.6 setup, 3800kbps wvga (h264) no single frameskip.
This isnt a joke, i finally found the problem of coreplayer on our HD2,
this will solve all your problems with coreplayer:
settings:
go to select page then video:
Video Output: DirectDraw (before you change this make sure there is no video running on coreplayer cus it will freeze your device, otherwize,
go to DirectDraw page and change Overlay to YUY2, then change Output to DirectDraw)
DO NOT USE GDI and RAWFRAMEBUFFER- unless you like choppy or framy(lol) videos. (make sure you have 1.3.6 one to get max performance with DirectDraw).
now this is important:
go to select page then DirectDraw:
uncheck Overlay with colorkey
uncheck Use blitting instead of overlay
check Use device streching for blitting.
Overlay: YUY2
go to select page then Advanced:
Soft-Drop tolerance: 0.300 /0.200 /0.250 ( personally i use 0.250 it seems better )
Hard-Drop tolerance: 0.000
check Disable AVC deblocking filter
( EDIT: about AVC deblocking filter:
with h264 you can see some annoying squares on the video sometimes, now i recommend to uncheck this option and use TG01-D3DM drivers from chainfire, although in 3800kbps videos you will receive skips sometimes, but dont use such high bitrate with coreplayer XD tried 2000kbps one and works smooth with deblocking enabled)
after you have done all this coreplayer will run very fast,
BUT we havnt finished yet!!
playback will still have slowdowns, and this isnt related to the settings,
it is related to a bug inside coreplayer, which affects the autoscale feature of the snapdragon.
have you been wondering why benchmark is so high while playback lags a bit?
I explored this thing, i can tell you that when i check "Play movie in backgroung", and watch the cpu speed: it goes down from 768MHZ to 400-300MHZ randomaly then goes back into 768MHZ, interesting isnt it?
when it drops down to 300-400 it has lags, and when it returns to 768, the lags stop.
the final solution:
http://www.netripper.com/leo/cpuspeed/LeoCpuSpeed_v2.zip
this program will allow you to keep the CPU in its position or make it full 1GHZ.
all you have to do is open it then tap "Disable autoscaling" and you will have Full 1ghz speed.
you can explore yourself by re-enabling autoscaling ("(Re)enable autoscaling")
then activate movie playback in background through coreplayer, then go to this software and watch the speed dropdowns.
now the "Disable autoscaling" is perfect for coreplayer, it also use 1ghz instead of 768MHZ, and also does not drop down randomally.
it is recommanded to activate autoscaling after finishing with coreplayer, so you can use more battery, it barely affects the speed of everything else but coreplayer, because it automatically increases to 1ghz when you switch between apps, but does not stay 1ghz inside the app itself.
(im not a native speaker, i hope you could understand this.)
enjoy guys.

Core player does not work anymore!!
Followed these instructions to the letter.
Core player stopped playing videos!
Had to hard reset and restore. Beware.
Edit: I am using (and paying for!) version 1.3.6
I hard resetted because reinstalling did not solve the issue.
Hard resets are almost painless when you backup regularly (I use SPB backup... excellent).

maybe you are not using the 1.3.6 version of coreplayer
thats why it didnt play any video (DirectDraw works only on 1.3.6 and one more version - at the others you get green screen)
anyway why hard reset? you could reinstall coreplayer..

It worked for me though.
The benchmark for video with following properties reads 140%.
Video: MPEG4 Video (H264) 848x480 23.98fps
Audio: MPEG Audio Layer 3 48000Hz stereo 128kbps
It plays smoothly. =)

glad this works for you,
dont forget the fix for the cpu slowdown, cus without this the benchmark is only a number, and the playback will be with lags.
can you post your bit-rate?

Thanks for the tip!
Btw, this might be kinda off topic, but do you know how to get the htc volume slider (volume slider as in HTC music player) to work in coreplayer when I press the volume rocker?
Currently, the video will pause whenever I press on the volume rocker to change the volume.

Umm i have no idea,
maybe you can search google, but i have another solution:
theres an option around coreplayer settings to make the video keep playing when it exits fullscreen, so all you have to do is increase volume, then go back to fullscreen and the video keeps playing..

working
"you are good, you are very good "
No more lost frames, works indeed but now quality is not so good, I see lots of artefacts on my lower framerate videos.
Maybe I messed up some settings ?

i guess you did, go over the color settings etc.. ( i use 0 on brightness )
there is absolutely no drop-down in the quality,
if i play the same video also in album - you cannot tell which is which if i show you both in fullscreen.

I made those brightnes settings and the artefacts are still visible .
???
Thanks for help

ummm i dont completely understand what "artefacts" is lol, (not a native speaker sorry, i used dictionary but the meaning doesnt make sense xD, maybe you should try to explain this better)
i do understand that the quality isnt like before, this means you messed up with the settings somewhere. i do not see any drop-down in the quality of my movies.

Artefacts are little squares on the screen when is lot of movement
Sorry for my poor english

got it, do you say these werent there before? actually this is common with flv files.
one more question: does it happen when the screen goes black?

yes these apear after your settings
I had first part of settings ( yuy2 ) and I guess they apeared after I did the second part of settings ( soft and hard drop )

nope this is defenetly not related to soft and hard drop, im thinking now with my hd2. but tell me if you mean those squares when the screen goes black, cus somehow in the past i solved this.

when the screen is black , the squars are not visible
when I watch any movie, video they are very ugly ( in some grey area )

i cant notice any squares, once i had them left on the black screen, but i solved this, there are no squares!!
try use videos with higher bitrate, usually low-quality videos cause squares, also i would recommend to go back to the default settings to see if theres any difference which i guess there isnt.
EDIT: try unchecking Disable AVC Deblocking filter, and tell me if this helps. (this massivily drops the benchmark)

strange because I did not see them before
How I can reset to the default settings ?
install again ?

Try enabling avc deblocking filter (in the edit last post)
im going to sleep... 2:00AM here, Cya.

when I enable avc deblocking filter those artefacts are not so visible
but now freezes the playback, is not so fluid like before
when I disable avc filter it is smooth but with larger artefacts
I give up and go to sleep, thank you a lot,
to be continued

REMIX OS - Best video player, best settings

Hi all. Been using Remix OS on the MOJO and loving it, but having some issues with media file playback. I usually use SPMC but I can't seem to set it so that that playback is smooth. I'm getting judders and stutters here and there, most noticeable (but not exclusively) on PAL 50Hz content and when the camera pans. Is there a different media player I should try, or what would the optimum settings be for the MOJO to produce smooth playback? I only have a fairly standard Samsung LE32C450. Thanks all.

NVM, I appear to have resolved it. I've had to set sync playback to display and sync to refresh rate on, and also always enable vsync. Never had to do this on previous versions, but the latest SPMC seems to need it. Playback fixed either way.
EDIT: Posting up my settings as I do indeed appear to have resolved the playback issue across all types of content, not just 50Hz PAL stuff. All video was rather juddery, but no more. Very pleased Anyway, maybe this could help someone else with the same issues:
Enable Expert settings within the SPMC menus.
1. Switch off Mediacodec (Surface) in Acceleration, leaving just default Mediacodec on
2. Set Vertical Blank sync to always enabled
3. Sync display to refresh rate - on
4. Adjust display refresh - always
Then when playing a file, go to the video options:
5. Switch Deinterlace off. Now you may have some files that need it on. You will have to set this to on for those files as you play them. Do not set it to auto either way. Auto seems to screw up playback.
6. Deinterlace method - Bob inverted (probably already set to this)
7. Video scaling - Bilinear (see above)
Then click to set as default for all media.
Let me know if any of this helped you or not.
EDIT 2: Please delete this thread mods, as this is no longer working for me.

[SM-G9750] [SOFTWARE BUG] Video playback being throttled or not utilizing CPU / GPU?

For owners of the SM-G9750 (S10+ CN / HK model), I'm trying to get some verification here on a possible software issue. I'm trying to play a 4K video file locally (specifically a 4K HDR H.265 / HEVC MKV @ 24fps video, but I believe this bug may apply to all UHD video playback - I'm not sure as I haven't done enough testing) and it seems to be dropping frames and stuttering throughout. I cannot get it to play smoothly despite trying all of the following:
Setting the phone to Performance mode.
Trying different players - in this case, the default video player, MX Player Pro and VLC.
Moving the video player app to Game Launcher and optimizing them for performance.
Forced 2D GPU Rendering in Developer Options.
Changing display resolution from WQHD to FHD.
Moving the video file from SD card to internal storage.
Disabling / uninstalling all apps which use Accessibility Services.
Clearing cache.
Factory reset.
None of these worked. ---UNTIL--- I tried using the screen recorder, from the Game Launcher settings, whilst watching the video. Playback was then perfect! No dropped frames, completely smooth, like it should be. The other alternative was to use software decoding but then colours would appear muted and battery life takes a huge hit.
So what's the deal here? Is the CPU or GPU not kicking in / being throttled whenever I launch a video player app? I'm assuming this is the case as the screen recorder seems to boost playback performance once I activate it. I'm on the June update and I'm not sure if this bug was introduced recently (I never tested 4K playback until now).
Owners of this particular model, could you please confirm if you are having this issue? Try watching a 4K video with lots of action and camera panning movements - that's where you can detect dropped frames or stuttering easily. I could provide the file I'm using for reference but it's a clip from a movie and I'm not sure if I'm allowed to share it here.

Okay since no one has replied and moderators on the Samsung forums are busy removing my posts - try this clip for example, it's 4K HDR encoded in H.265 / HEVC, I don't know if that makes a difference:
http://www.mediafire.com/file/m83ftn7n8d8le2s/Plane_Crash_Scene.mp4/file
Stutters in the default video player app for me. One thing to note is that it's smooth in portrait mode, but the moment you rotate into landscape fullscreen, it starts dropping frames. Now, turn on the screen recorder from within game tools and the stutters are mostly eliminated. What gives?
Another way to compare would be with a video player that lets you switch between hardware and software decoding, like MX Player. Watch the clip in HW mode and then switch to SW - it's choppier in HW mode for whatever reason. Using SW is not an option as the colours are not displayed properly and battery drain is much higher.
Regarding the clip - if it's against the rules to post such content, let me know and I'll remove it. There's a whole YouTube channel full of this stuff, I don't want to link to those as the problem I'm encountering is related to local video playback.

One last try before I sign off Here's another example if anyone has YouTube Vanced (google vanced.app for those unaware). I'm suggesting Vanced because the original YouTube app doesn't let you view at 4K resolution.
Firstly, open Vanced and tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Now open Game Launcher, tap the three dots in the upper right > Add apps and add YouTube Vanced to the list. We're doing this for the screen recording function which I'll mention later.
Once that's done, here's a 4K 60fps clip for you to try. It should be easier to perceive any hiccups with the higher frame rate. And of course, please set the resolution to 2160p (tap the three dots in the upper right) and watch in landscape orientation, since this is what the test is all about:
https://www.youtube.com/watch?v=LXb3EKWsInQ
Panning shots work best. For reference, see the one of the step trail at 2:42 in the video. Does it look like it's stuttering or dropping frames intermittently?
Now, swipe up from the bottom of the screen to show the navigation bar (you need the navigation bar enabled to use the recording function) and tap on Game Tools, which is the leftmost button. Tap Record.
While the screen is recording, are the stutters now gone? To my eyes, the video is definitely smoother while the recorder is active. Appreciate any feedback from those willing to try (and confirm if I'm insane or not!) - cheers!
