Video playback problem (not that it's slow). Garbled screen.

So it seems that I'm unable to play back any video format besides WMV.
WMV's play back fine while other formats (e.g. xvid, divx) do not play back at all. Coreplayer crashes to today screen or shows me a green garbled screen with vertical lines.
WMP just freezes and does nothing.
Is this a known issue (I didn't find anything using search)?
Any format of audio plays back perfectly fine (as long as it is not embedded in a video).

I had this, you need to change the Video driver to Raw frame buffer and all will be well. I use TCPMP and this was what I had to do for it to work.

I had done this at first initially too, but simdeo (fellow member) suggested Imageon setting, but NOT Imageon Hardware decoder. This has massively improved speed and visual quality, but you will get intermittent lines across the interface, but not in full screen mode. Settings should be:
TCPMP:
Video Driver = ATI IMAGEON
Buffering = Microdrive (ticked)
Advanced = Tick only: D-Pad, Use System Vol, Benchmark (none od these settings affect performance, just my preference - but selecting other options may adversly affect performance)
Direct Draw = YV12 and tick 'Overlay with colorkey' only.
That's it. Best performance to date and can play torrent or own DVD rips perfectly, providing they were not encoded as high as 640x480.

I'm having the same problems but cannot for the life of me find any settings on Coreplayer that will let me change the buffer settings or the driver.
I'm sure I'm missing something here.
Coreplayer version =1.0.4 build 716
It's the latest version afaik.

Ok, I found the settings in Coreplayer (yeah, I know, should have looked harder..) and all is now well.

Ok, so I've got really decent playback from standard 350mb XVid TV programs but I'm still having what appear to be buffering problems.
Does anyone know what the ideal buffer settings are?

I have found that overclocking the CPU yields in much better playback (although not perfect).
If I want to view a 640x480 video I run the CPU at 728 Mhz (what program would allow higher?), but still the fps is not up to par. I would say the playback is around 90-95%.

Hi Calavaro. What app are you using to o/c the CPU? & exactly what settings do you use? Oh and lastly what's the power consumtion like if left on 728 Mhz all the time?
Cheers.

we use PHM to overclock our device, if you set to 728 and push mail and bluetooth all the time, you won't last for whole day, maybe just about 7 hours. But really you don't need your device on 728 all the time, and personally i think 728 is a bit unstable, so i use 662 when my device is on, otherwise 228 the rest of the time to save battery.
You MUST disable the internal scale from the PHM setting, otherwise it won't work

just wanted to say thanks for this thread. was going nuts with the same problem re: vertical lines, pink screen, etc. almost made a post to ask you guys what kind of parameters or settings you used for your video players. i use core and i confirm that the "raw frame buffer" works well.
cheers

About TCPMP with the best settings applied as mentioned in this thread, is there something else we can do to further improve the playback quality?
I have some clips that feature "fast moving action" e.g. action scenes in movies. These clips will actually play, but when the "fast moving action" is there, you can see that it isn't going really that smooth/fast enough, resulting in noticeable, fast upcoming blocks/lines when you look closely. I'm not sure how to describe this effect best, but I guess pretty much everyone knows what I mean here.
Thanks!!

Hi.
Try playing any 3 minute segment of the video you have then click on File/Media Info and check the resolution of your video. If its below 640x480, then the problem is most likely a low bit rate used to encode the video, hence the pixelated blocks in high speed.
You can get away with less, but I encode now only at 480x320 @850kbps and get superb results each time...DVD quality and High definition quality too when I encode from HD source.
Can't say anymore than that. Click on my name and look through my posts, there will be a recent one entitled something like 'Excellent playback via Coreplayer & TCPMP'. This should help a bit if you have the time to read.

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
- Normal Buffer Size: 2400KB
- Preload at underrun: 70%
- 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
QTv
TyTN II driver mode - Yes

Coreplayer 1.3.6 Judder - stock ROM 1.48 (SOLVED)

I've done a search and read many posts about coreplayer performance on the HD2. Most have no problems but some do and i'm one of them.
I have no problem playing the files using these settings from member Shasarak (thanks mate):
Options/Video and activate Dither, then "smooth zoom always" rather than "smooth zoom 50%". You will get substantially better performance if you then go into the DirectDraw settings page, choose "YUY2" as your overlay format, leave "use device stretching" checked, and uncheck the other two boxes.
I have tried all other settings and combinations but i agree the above gives the best performance.
However, i am still experiencing occassional judder and it's annoying me.
1). would upgrading to stock ROM 1.66 make a difference?
2). is there ANYTHING else i can do to stop the judder? i've already tried disabling background tasks, wifi etc
3). The audio is also very slightly out of sync, it's delayed, it's minor but i notice it. It happens on all videos, they are all .avi I've not seen anyone complain of this before.
Thanks

With regards to uadio sync:
Menu --> Tools --> Settings
Select the 'Advanced' page
Manual A/V offset let's you adjust the audio sync

The judder is most likely due to the format the videos are encoded in just eating too much CPU. How do you encode them?

I don't encode them, just downloaded movies in the common divx/xvid format. I played movies on my old N96but re-encoded them to mp4 as it didn't play avi and i never tried coreplayer on it.
Perhaps i should try re-encoding, but don't see why this phone couldn't handle a standard 700mb divx avi.

cheers mate, you are the man! putting a -0.300 has made it much better, not sure why it would be out like that on all movies? I'm very happy with that What do the other 2 settings do - soft drop tolerance & hard drop tolerance?
now just to fix the juddering.
I've found, and i think someone else suggested this in another thread, that if you pause it for a moment it sorts itself out. Would rather not have to do that but i don't see a way around it

The standard ~1h30 700MB divx movies I've tried to play all worked nicely. But sorter ones of the same size (meaning more bitrate) could start being too much load. Just try and do a benchmark in coreplayer with a video that causes problems, if you have less than about 150% average playing speed you might start getting drops.

It may help to put the phone in "Airplane Mode"; if it's checking for email messages in the background while playing it will judder like crazy. Use the task manager to kill off any other running applications as well....

I come to the conclusion that this phone just can not handle playing divx/xvid in avi very well, and i'm not sure why it can't.
I have gone back to my old ways of converting the video to mp4 using winavi mp4 converter, this also cures the problem of any files that have ac3 audio as it converts that as well.
On my 8 year old computer it would take 30 mins to convert a 700mb film, i have since bought a quad core Dell running 64 bit windows 7 and it converts in less than 10 mins!!
Smooth as butter now but a shame i have to go back to doing this. But at least the files will play in coreplayer, windows media and htc's player so plenty of choice
If anyone wants the settings i use for winavi mp4 converter then just ask away. It's not free but mine was if you get what i mean
EDIT:
I HAVE FOUND THE REAL PROBLEM, IT'S MY COREPLAYER! IT STARTED STUTTERING THE MP4 FILE THIS MORNING, WHEN I SWITCHED TO WINDOWS MEDIA OR HTC PLAYER IT WAS FINE 9OBVIOUSLY COULDN'T DO THIS BEFORE AS NEITHER OF THOSE PLAYERS SUPPORT AVI)
I JUST TRIED COREPLAYER AGAIN AND IT'S PLAYINNG THE SAME MP4 FILE FINE NOW, MUST BE SOMETHING WRONG WITH MY COREPLAYER, WILL GET ANOTHER VERSION.
WHAT A DRAMA AND SORRY FOR BORING YOU ALL WITH IT LOL

Coreplayer, Smooth than laggy, and perfect in benches??

Hey guys just got a slick HD2 from Tmobile, and I wanted to check out Coreplayer. I started playing a few WVGA videos with decent bitrate, and towards the first 10seconds video played fine than started to lag and drop frames, then when I skip to a different part, it plays smooth for another 10secs than lags. When I run benchmarks, the video scores 120%.
I am using these settings for optimal playback.
Tools:
>Settings:
>Video:
Video Output: DirectDraw
Video Quality: High
Smooth Zoom: On
Dither: Checked
--
>Direct Draw:
Uncheck Both “Overlay with colorkey” and “Use blitting instead of overlay”
Check “Use device stretching for blitting”
Overlay format: YUY2 (or RGB to enable Dither)
--
These settings give me best visual quality, tell me if there are better settings.
However, the above problem occurs, in many different configurations.
I believe the process priority is the concern here, I think Coreplayer auto ranks up the priority during benches but doesent seem to do so while playing, most likely to conserve battery life.
I was reading a long time ago about a program that increases process priority in Windows Mobile, and was hoping that it may do the trick. So can anyone lead me to the rite softwares???
---Edit: I tryed to change the priority but it is always set to highest, in benchmark mode and in normal playback. Does anyone know what could be the problem.

I think those are pretty much optimal. (RGB overlays are definitely slower than YUY2).
Try putting the phone in "airplane mode" and then rebooting it; that sometimes helps. If it's doing something like checking for emails in the background it starts to judder badly.

if core player has a buffer size setting try setting it higher try setting it to 32864kb. or do what i do and use TCPMP for videos. it has that setting and it works great for all vids. oh and its free! search the forums for TCPMP if core player ends up not working for you.

I've found that CP benches don't mean Sh*t, I can get 175% in a bench but play it back normally and it still drops frames

Yeah, the benchmark obviously displays average frame-rate; what you need to know is the time taken to render the single slowest, most complicated frame.

If I choose DirectDraw my device.exe locks up. I have had to stick to GDI. I only drop 1 frame every 300 to 500

That is probably because you are not using the other settings correctly: YUY2 overlays, etc.

Selecting DirectDraw alone will make CorePlayer crash. You need to make sure you set all the other settings in the 1st post too and then it runs much smoother than GDI.

[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!
