Horrible CorepPlayer performance

Dear friends,
I really hope someone can help me with my never-ending struggle with CorePlayer 1.1.1.
It pauses every few seconds, for buffering I guess.
The video (DivX AVI) is stored on the MicroDrive. Now what are the setting I need in the preferences - buffering menu? I tried a lot of different values, some of them work better than others, but the lags remain.
Right now it's:
Normal buffer size: 2400 KB
Preload at underrun: 70.0%
Preload for audio: 64 KB
Microdrive mode: ENABLED
Microdrive buffer size: 24000 KB
Microdrive starts at: 1472 KB
The file details are:
DivX AVI
940063 KB in size
Video: MPEG-4 video
Core: CoreASP
Video Size: 640 x 362
Frame Rate: 25.0
Audio: MP3
Codec: CoreMP3
Audio Format: 44100 Hz 2 Ch
Data Bit Rate: 192 kbit/s
---
Something else that's strange:
CorePlayer doesn't remember my zoom setting in options - zoom.
E.g. when I set "Fill Screen" it's back to "Fit Best" after closing CorePlayer.
Didn't have that with TCPMP. Is that a known thing or is there a trick?
Thanks people!!

Update: some of the video's play FINE when I mute the audio!!
How to work with that?
CorePlayer still doesn't remember the zoom setting though.....

hey mate
i had the same issue with coreplayer some time ago. i found a thread somewhere in the athena section about this. i can't find it anymore but here's the settings that i did based on that thread. basically it was the recommended settings...
=============================
buffering page
Normal buffer size: 2400 KB (same)
Preload at underrun: 70.0% (same)
Preload for audio: 64 KB (same)
Microdrive mode: ENABLED (same)
Microdrive buffer size: 24000 KB (set at 16000)
Microdrive starts at: 1472 KB (same)
============================
video page
video output "raw frame buffer"
video quality high
============================
advanced page
d-pad follow screen (enabled)
use system volume (enabled)
benchmark from current position (enabled)
manual a/v offset 0.00
soft-drop tolerance 0.055
hard-drop tolerance 0.700
=============================
ati imageon page
enable all of them (6 items)
=============================
============================
hope that helps. for me those settings give me the best video quality while at the same time in sync with the sound. i used to have the same issues you have where the video stops while the sound is still there. but after switching to the settings above, i've had no issues ever since. i can even watch direct dvd rips on the sd card and there are no issues whatsover.
cheers

That direct dvd rips you play, at what resolution are those?

not sure, but these are avi files that i downloaded straight from the internet. average size is around 700+ mb. when you play them on your laptop they take up the whole screen. with coreplayer, i guess it fits itself in the screen as well.
part of that post i mentioned (the one where i got the settings) also had an attachment that you can use. it's an avi converter which optimizes a present dvd rip (avi) to fit best in a pda screen. i'll see if i can find that thread.
cheers

Best settings for CorePlayer?

I am trying to get the best video using CorePlayer, mostly for YouTube now. I will start watching DVD's in the near future as well.
What are people seeing as good settings?

after installing coreplayer set the buffer size to 2400 and the preload underrun to 70 and that should give you perfect playback

Where are these settings? I just bought and installed the latest CorePlayer for Windows Mobile (1.2.5 build 4506 for ARM) and I don't see these settings anywhere under Options or Preferences.

Menu, Tools, Preferenfes - then click Select Page and pick what you want to adjust. There are some other pages that people recommend settings, but I haven't found one that really sticks out yet.

Thanks, Ryan; I never would have found it--"Select Page"--that's a new one on me.
"Preload at underrun" is located on the Buffering page. Interestingly, both the buffer and the preload at underrun came preset to the values that Dominican706 recommended.

i to would like to know if there are any optimal settings for watching .avi on my mogul in TCMP. i looks very nice with stock settings and for the most part plays well but it does tend to skip every now and then. i was watching a file on my SD card if that makes a differnce

Please, anybody knows what Microdrive mode does from the Buffering page in CorePlayer?

CorePlayer stutters on video playback - HTC Album not?

Hello, I'm new @ xda-developers and got my touch hd last week.
While playing around with different video-encoding-settings to get optimal results I found the "HTC Touch HD Video Converter" in this forum.
I used it (v. 1.18) to encode a video from a 1080p source file.
I chose "HD input" and maximum resolution "WVGA 800x480".
My "problem" now as follows:
Using CorePlayer 1.30 results in heavy-stuttering video-playback whereas the HTC Album plays it very smooth, even in fast-motion scenes.
I already played around with some settings in the CorePlayer preferences menu but I can't make the video run as smooth as it runs in HTC album.
The "tnyynt SD TuneUP.cab" is already installed by the way.
I want to make CorePlayer work as intended Does anybody have an idea what I could do in order to solve this video-playback-stuttering?
Thank you for possible answers

This is already known. WMP (or HTC album) have some hardware acceleration, whereas CorePlayer doesn't provide this yet. Future releases of CorePlayer are supposed to have the hardware acceleration as well.

Okay, thanks a lot

Reduce buffer size
i've solve this problem via reducing buffer size:
Menu --> Tools -->Preferences --> Select Page -->Buffering
my new settings are:
~ Normal Buffer size 1184 KB
~ Preload at underrun 70.0 %
~ Preload for audio 0 KB
but this aajustment is for an internet radio, let me know if it has helped to solve your problem please!

Is there still no hardware support in CorePlayer ?

Coreplayer Configuration

Since changing my Rom and upgrading to coreplayer 1.3.6 the video quality has degraded so that now even media player is better.
When watching a video, sometimes the video freezes, but the audio carries on. I usually change from fullscreen to normal mode and back to full screen and the video carries on as normal
I used to be able to read the text in a video, its now degraded and barely legible. I checked the video in media player and it looks better.
I was going to post this query in the coreplayer forums, but I noticed how many of the treads actually had replies.
I've tried googling for configuration settings, but all I found was HD2 config settings, some of those settings arent listed in my configuration.
Does anyone have any suggestions on how to improve the quality of coreplayer video?

What was your coreplayer settings before you changed rom? If your settings worked before you changed rom then just set it to what it was before.
Anyways, my coreplayer settings are;
set everything to default then in tools-settings-advanced
tick disable avc deblocking filter
set soft drop tolerance to 1.000
set hard drop tolerance to 1.100
these configurations work best for me
I hope it solves your problem

Thanks for your reply.
My settings were probably default before I had to flash a new rom, it seemed to work fine, so I didnt muck around with them.
Just to confirm I have Coreplayer 1.3.6 build 7427.
I have Tools => Settings => Select Page where I can select VIDEO, BUFFER, etc. I dont have an advanced option.
I couldnt find any of the options you mentioned either.
Is there a way to reset the settings to default? I cant find any options.

The only way i know to set everything back to default is to install it again.
tools-settings-select page-advanced. you have to press select page then go to the advanced page
I have the same version coreplayer as you

Lol, you're right. Sorry.
I didnt realise that I was able to scroll that screen up.
I did some more searching and managed to find this link:
http://forum.xda-developers.com/archive/index.php/t-481714.html
It had the following setting suggestions:
Htc Touch Hd
Select Page ---
BUFFERING:
Normal buffer size = 992 KB
Preload at underrun = 70.0 %
Preload for audio = 0 KB
Microdrive mode = checked
Microdriver buffer size = 16000 KB
Microdriver starts at 1472 KB
VIDEO:
Video output = QTv Display
Video quality = High
Smooth Zoom = On
Dither = Uncheck
ADVANCE:
Slow video memory = Check
I entered the above settings (except the ADVANCE).
On Testing I found that coreplayer played fullscreen video for 10 mins without a problem.
I havent tested the clarity yet (ie being able to read text), but will do so this evening
Thanks for your help.

If you read further down that thread, you can see that I also participated in that discussion. I believe it was barisahmet that suggested playing with some of the advanced settings. I have since stuck with the current settings that I mentioned above because it works best for me.
Glad to be of help!

I found coreplayer was still having problems. My audio wasnt syncing with video.
Despite mucking about with the settings some more, things didnt improve.
I tried uninstalling and reinstalling to wipe the settings, but that didnt help.
I eventually found the settings were stored in Application Data\Coreplayer\Config.xml.
After renaming the file, things went back to default.
EDIT: Just thought I would add that this is also where coreplayer keeps the serial number. Really secure
If you're comfortable editting xml files a better option would be to delete everything between the <CONFIG></CONFIG> tags.

[Q] Video - got conversions right but new problem

So I must admit, from a video playback issue, I've never owned a more frustrating device. That being said, because I love everything else about the XOOM, I've been willing to work to achieve good results. I have achieved great video quality with encoding times similar to what I saw when targeting my iPad, and file sizes that are totally manageable. I have attached the Handbrake profile I'm using. I hope everyone achieves similarly satisfying results. I am using Rockplayer.
OK, on to my new problem. Whenever I adjust the volume and it brings up the volume slider, the video slows though the audio continues, dropping the video out of sync. I have to jump ahead or back to bring the video back into sync. It is similar to the lag in video playback that happens when I first launch the video, but in this case, the playback corrects itself within seconds. Can anyone help with this issue?
I've messed with my XOOM like crazy since getting it, constantly installing and uninstalling applications and files. Could this be an issue?
Thanks in advance for your help!

While using RockPlayer are you using software or hardware decoding? Go to settings, scroll to the bottom and see if hardware decoding mode is checked. If not then check it, but please note you will have to uncheck the box when you want to decode non converted formats like Divx, Xvid, and MKV.
P.S. If all of your video files are properly converted H.264 videos with .mp4 containers you should be able to use use the gallery application to play all your videos, and if you don't like the gallery application for videos you can just use a file manager like astro or IO to select the videos from their folder and play them with the built in video player.

I personally use Total video converter & I have no problems with my video or audio.handbrake just wasn't what I was looking for.total video converter works flawlessly.

Some people have reported similar issues when using HB for various Droid models.
Personally I use the build-in Gallery for video playback, because it makes use of the hardware acceleration.
If you are interested, I have a few samples of 720p and 1080p video files on my website that play perfectly on the Xoom. Links on the site will stream as well.

Yes, I'm using hardware decoding in Rockplayer and I always used Handbrake for my iPad and Epic without issue. When I use the native gallery video player, the problem is worse, as the video starts to lag just from bringing up the playback controls. This is very frustrating. I will try some different converters and see how that goes.
Dvdcatalyst, I will give a few of your videos a try and report back.
Thanks everyone for your thoughts.

DVD Catalyst works great. I use the stock player and haven't had a single problem.
(Change the video quality to 1750 kbs in the Xoom preset).

i have no problem switching to DVD Catalyst but have one question...does it have the ability to monitor a folder? One thing that is so attractive to me about Handbrake is the ability to use Dropfolders to monitor my DVR folder, automatically convert recordings and dump them into my Dropbox. This makes all my recordings instantly available when I'm on the road.
Thanks

I tried RockPlayer a couple of months ago, and when it was still in beta, but I always come back to the default Gallery. I have never experienced sync or playback issues on the Augen Gentouch, Nookcolor, Droid X and the Xoom, but have heard numerous reports from people for all of these devices (and others) regarding other methods.
For the settings I use in my own software, for all devices it has profiles for) I make sure it plays as it should without the need of installing a different video player. Only for a few older iPaqs and Palm devices do I recommend the install of something else (TCPMP), but for Android, Gallery (or a player like Act1 which acts as a layer around the Gallery player to add new functionality) never gave me playback issues.

Sorry, when I use DVD Catalyst with the XOOM profile, the video comes out a stuttering mess. Here's the info on the files I'm looking to convert...

It looks liek for some reason the framerate of the created file isn't processed correctly.
I noticed you used a SageTV Recording, could you create a small recording and email it to me, or maybe PM me a download link for a small (1-2 minute) clip?

Additional detail
Additional detail regarding my problem - what I've discovered is that the video plays fine but it's only when the controls from Honeycomb are overlaid that the video playback begins to lag. In Rockplayer, bringing up the playback controls don't cause the video to lag, only the volume controls which are native to Honeycomb. Any additional thoughts? I'm thinking about wiping the system and starting from scratch to see if that makes a difference.
Thanks

thanks, I'll have a look at it in the morning. I am working on a small update that includes new Xoom profiles (the settings mentioned on my website) and will take this along in the process as well.

Shocked but I think I figured it out
OK, I'm shocked that I've actually figured out where I was going wrong. The files I was converting and having issues with were recorded using SageTV from a cable box set at 720p. 720p is 60 frames per second and Handbrake was set for FPS to be same as source. When I changed it to 29.97 FPS, I no longer experience issues with video lagging the audio when I adjust the volume or bring up the playback controls. I don't know if this is an important find, but I don't think it's a limitation limited to the XOOM, as I noticed my conversions using the iPad preset are also limited to 29.97 FPS.
I think I can go to sleep now
