HD2 Poor performance. CPU or GPU Slowdown with battery. - HD2 General

Well, I have evidence that the phone slowdown the CPU or the GPU or both when the power is only the battery. You can try it...
Download the 480p Avatar Trailer: http://www.megaupload.com/?d=NORWI55K
Open the video with Coreplayer. You'll see that there're lag.
Now Plug-in the phone to the charger and Open the video again with Coreplayer. The Video plays smoothly without lag.
How we can make that the phone don't slowdown???
I'll wait your opinions.
Cheers!

Strictly no difference here.
It lags just a little in high motion, but it's actually pretty good given the format. And great quality.

First of all, you must see the video in full screen.
Look at time 00:38 seconds when the head of the robot closes. With battery there´s a lot of lag, but when you plug-in to the charger is really smooth and no lag.
Cheers!

Nope, smooth both with and without for me.

ok, what rom/radio do you use?
Anyone more test it?

Maybe you're using some sort of old stock rom that for some ungodly reason has this "feature" enabled?

Artemis 3.7

Anyone more test it?

wtf is .mov format?
i have laggy to...
but i think its format problem

Coreplayer can play it.
Try it with your phone plug with the charger and tell me if lag go out and video plays smoothly.

Touch HD Video Playback Performance Concerns

So here's my story:
I recently bought Samsung Omnia on which I did extensive tests on video playback
with CorePlayer 1.2.5 and TCPMP and with various video formats such as:
H264 Baseline 3 480x272 (originally encoded for playback in iPod Touch)
Various XviD encoded videos with resolutions varying from 640x360 to 720x400
Using DirectDraw as video output in both CorePlayer and TCPMP
the result was awful, dropped frames, awful motion and distorted colors.
However since the Omnia has the fastest CPU I know in WM Device so far,
the Marvell PXA312, 624MHz with IntelXScale acceleration,
the CorePlayer and TCPMP gives this as an option for video output the IntelXScale acceleration.
So when using this setting the video playback of any type of encoding was absolutely beautiful.
Colors were correct, performance was amazing (even in double playback speed) it was in general as smooth as it gets.
For a powerfull (hardware-wise) device such as omnia, I was very disappointed
in the resolution of the screen (240x400 - wqvga) and its size 2.8".
For this kind of device which has literally everything one would expect it
to have same screen size and resolution as the touch hd.
I rushed to buy this device I must admit and so I sold it to a friend after experimenting with it for one week.
The reason that I gave away so fast the Omnia was simply the Blackstone.
Since I am kind of perfectionist as far as it concerns screen resolutions, the touch hd is no match with any other phone/ppc device out there.
So here comes the real concern, how is the performance on video playback on the blackstone?
For a multimedia device like this one would expect that the performance
would be excellent (much like the omnia or even better if it can).
But what concerns me is the Qualcomm cpu at 528Mhz which as far as I can tell
doesn't have IntelXScale acceleration (plz correct me if i'm wrong on this)
So if it uses only DirectDraw and the results are crappy, then this would be such a turn off.
Can this CPU give a smooth video playback performance on a 640x360 XviD avi video
with "Smooth zoom: ON" and "Zoom: Fill Screen" settings on either CorePlayer or TCPMP?
And keep in mind that we are talking about realtime upsizing of the video to 800x480
which IMHO requires quite a lot of cpu power for such device.
Because really I am not willing to spend 700 euro on a multimedia phone
that can't actually perform well on multimedia.
I'd love to hear someone that has it and tested it on that matter.
Thanks for reading!
We really want to know the answer for your question, And I think that we have to wait until we see the phone on the market and get some benchmarks.
Also I think that SE in their xperia phone did what you are asking for ..! In the same beautiful screen resolution 800x480
Thank you,
Mohammed

More like SE said to HTC "We want an awesome phone, but we don't want you to tell us what's in it, and we'll just make Magnus make up stuff as we go, also we suck at marketing."
touch HD has a slower cpu, without xscale acceleration. but it has a dedicated graphics chip, which matters more in video play back. at the resolution you have mentioned, i have full confidence it will do just as well if not better than omnia.

I sure hope so, because I would say I'm not so satisfied with the Touch Diamond performance. Let me explain:
Since this matter is really killing me, I need to be sure it can perform well on video (not extreme stuff, the standard-like video formats we all use).
So I decided to make a test, since i don't own a Touch Diamond (which has the same hardware), I went to a local retail store that had the device on display for ppl to see and experiment with, I installed coreplayer and sent a 40" 608x400 xvid video with ~900kbps bitrate to test it.
CorePlayer was set automatically with video mode QTv and with TytnII Driver mode enabled (which i suppose is the accelerator driver)
I made sure nothing else was running in the background and the results was not so ok. I was playing just ok, I noticed some frame skips and some "lag" in fast motion.
I just hope the Touch HD has revised hardware (if that's possible) and better drivers maybe?
I really would like to hear an answer from someone that has already his hands on the touch hd

No, i'm saying that coreplayer/TCPMP will only be able to use the default qualcomm chip, its exactly like having a graphic card in your pc with no drivers and no in built support
Thats sux
I hope Touch HD has better driver ... because the hardware is the same.
Quite a downer ...

If that is the case, then I dont understand it. I mean why HTC would go through all this trouble to have an extra graphics chip in their devices when no other than their own app could ever use? So they put a graphic chip with 3d capabilities and video acceleration for just their own apps like touchflo 3d ?
Isn't it just stupid?
Yes, that would be stupid. Fortunately though, there is quite some talk about the HD having an optimized chipset compared to the Diamond, even though this does not include the processor. It is already evident by the many movies that the device performs faster than the diamond even with the same processor, so I doubt you'd have exactly the same performance issues as with the diamond. Though there is only one way to be sure: wait 2 more weeks and everybody will own one.

Thanks to johnkorver who own the device, create the video review, and upload it to youtube.
looks promising even though we don't have any other info on the video file except the codec used (xvid).. anyway upscaling works nice and that says much..

Xperia performance

Hi all,
what others thing about Xperia's performance? I have it with original En ROM and it seems like not good performance, because when im playing some videos from youtube i can see missong frames, or some another videos with for ex. played in CorePlayer then it is slow like on an old PC, in CorePlayer it has to be set on medium quality to get videos playable 25fps
Help me please...

I see dropped frames on YouTube on my 3GHz PC too, so this is not hardware limitataion, could be streaming error.
Coreplayer is being developed, a new version is said to have the hardware acceleration for Qualcomm chipset, we just have to wait
But those movies on youtube are ok, on PC no error, streaming ok
to the coreplayer, on my old FSC N560 the same movie gets about 3mbps in bench. in high quality, on Xperia it gets about 2mbps on medium quality
Now i tryied on N560 some MKV video with 5mbit datarate, it is quite slow, but watchable on medium quality, on xperia not at all...

change settings to h.264 medium quality for youtube movies. the playback is great. I just experience the problem at the end of the movie when it trys to reload and that crashes my phone. I have to take the battery out. Try it, it might work for you.

I don't know because I could never get it to work properly (to be honest I do not even know what to install and what not - i am having problems with landscape mode). You really should try the coreplayer settings. apparently what i am experiencing is not a common bug, perhaps i have something installed or sth, will have to do a hard reset when i have more time and try again.
Settings in CorePlayer offcourse hepled, thanx a lot for that...Now it will be nice if some CorePanel is lol...

youtube on X1 is slower than my 240mhz wizard

I have tested youtube on several x1 Roms and i am extremely annoyed with how pathetic the situation is. The only way to play the videos at full framerate is to drop the quality to "fast download". Otherwise its just too choppy
Roms with new ati drivers are a bit better but are still slower than my 3year old overclocked wizard.

Can you say what ati drivers did you upadated and where did you get them?
EDGE or HSDPA ??
The internet speed difference is brutal...
You gotta compare the resolution between the two. The Xperia has much more pixel to render. So yeah if we put a QVGA LCD on the Xperia things will be fast as hell.
Anyway I can still watch Youtube videos smoothly with the high quality chosen without any problem.
for updated drivers i used jockeys rom 1.08
for both devices i used wifi and the demo version of core player and htc's youtube player
the x1 has 5x the resolution but the videos are only slightly higher than qvga for the standard video
nktpro, what Rom are you using (i want to test it)can you test this video: just search "gears of war mad world" you will get 1 minute that plays perfectly on my overclocked wizard but not on X1. thw x1 pic quality is *slightly* better due to its screen. overall the experiance is still better on the wizard due to the full frame rate
I watched the gears of war trailer and it run smooth on my x1, no lag at all. I thinki the internet connection might be your problem.
youtube by wifi is working fine. but use the htc youtube player NOT core player.
the core player is a very good program, but not the includet youtube browser.
the video quality is very poor. the same movies with htc youtube player, with high quali option set, is much better. its different like qvga to vga. and the picture is much clearer at all.
Use HTC youtube player. I watch youtube HD videos in full screen with max frame rate. No lags/slow downs whats so ever. Core player sucks at playing youtube videos.
i am using the htc you tube player.
if its playing perfectly (30fps) on many people machines then it must be my problem. im using rom (chalid 0.03) now.
what rom are you using i need to flash to something else to see if it helps

Leo Video Performance

Hi there,
A couple of questions from a HD owner about the Leo.
Can anyone comment on the video performance on the phone if you drop a non converted avi file/movie. HD used to stutter and get out of synch... Can you use VLC or CorePlayer with any file? Is it smooth?
Also anyone notice lag in the interface?
Love the phone, but I want it to run ABSOLUTELY smoothly... While the HD is fantastic, it's still get frustrating to use at time.
Lots of people have already commented on it. There are threads for those questions, give them a read.
What a waste of a response... It feels like the assumption on this forum is that everyone has time to go and read EVERYTHING and/or that search engines are so developed, brain usage should become irrelevant...
Pathetic...
Depends on the size and bitrate of the avi file, as well as the background programs running. I tried running a 848x480 882kbps(video) avi file and sometimes it stutters every minute or so, sometimes it just runs smoothly. Let's just say that... it's perfectly watchable. Not any moments where I can see the video being tremendously out of sync with the audio. Also tried a 704x400 826kbps(video) XviD file as well... and that runs fine.
I was using CorePlayer.
I don't have any HD avi files, but trying to play HD mkv files fail. (just manages to play 400px-height mkv files)
Using Coreplayer, video's have screen tearing when using directdraw but the performance of playback is good.
What I did was switch to GDI, no more screen tearing but the benchmark score is lower than directdraw. Also changed the smooth zoom to always be on and not only at 50%. This help reduce pixellation.
A standard tv episode avi file (624x352, 350MB) that can be found on various sites runs perfectly fine.
I think the developers at Coreplayer need to add some sort of hardware acceleration for the HD2. Maybe QTV or something along those lines...

How hard is it to look down the list of posts on the first page even? The thread is there. Perhaps you really do have a problem with brain usage.

just wanted to know how you where able to play xvid file? I got some strange green lines on coreplayer and huge lagging on mobile divx player, and it was a standard 700X400 clip.
Here's a nice sample I've made for the HD2.
http://gamesquare.co.uk/leo/toystory3-tlr1_h720p.mp4
Play in the album, this video shows the HD2 screen off quite nicely!
(800x480, 1500kbps x264, 128kbps AAC-LC, 1-pass)
Encoding was done in xvid4psp with custom settings.

Handbrake: encoding 720p video that isnt jittery

Ive searched for various recommended settings and tried the ones from this thread:
http://forum.xda-developers.com/showthread.php?t=1060825
And, for the most part, the videos are fine but what gets me is in situations where the camera is panning there is a noticeable jitter to the movement. Its consistent. Its only happening on the TF. I can play the encoded MP4s/M4Vs in VLC on the laptop and no jitter.
Id really love to get rid of this, it kind of kills the experience of watching videos because I like to watch shows like Top Gear on it and they pan a lot like that, although it does impact other shows. Its just more noticeable because it only happens when the entire camera is panning around subjects in way that most of the image on the screen is moving.
Im playing in the gallery BTW.
Hi,
this is a well known problem with the google libaries for hardware decoding. Until we get a update, there are only two solutions:
Use software decoding. Apps like Rockplayer, Moboplayer... have this option.
Use a Flash-Player. There is no stuttering with the flash libaries.
Does software decoding drain more battery?
And upcoming HB3.2 is supposed to improve hardware decoding of video files ...

I hope because I have not had good luck with rock/mobo and HD content. Right now playing with the stock gallery is the best option I have seen. I was just hoping maybe there is something I could do to drop the compression or quality (without sacrificing HD) to get rid of this odd jitter.
Its a shame too because its the only thing that lets down the media experience. I have had multiple people interrrupt me on the plane to ask about it the screen is that good (well, than and after seeing me snap my netbook in half and put it back together ). Heck, even ipad guys have complimented how things look on it (and their screen uses the same tech IIRC).
I builded a very simple html site in the last few days which has the jwplayer flash player. This is the best way to watch hd content with less than 29,xx fps without the stuttering. Maybe i will put it online later today.
If you want to hard telecine the material you can remove most of the judder.
It's an unfortunate side effect of the GPU decoding that we haven't yet pinned down.

Is there any way to load MKV files with JWPlayer without naming them and their location in HTML? I'd prefer a browse option myself. Otherwise it's pretty useless to me.
I tried using Handbrake to encode to "Apple TV 2" preset. which is basically 720p in mp4 file type. It plays back very smoothly with rockplayer lite, mVideoplayer or moboplayer.

actually its not smooth at all, there's still a minor lag which is obvious to my eyes..so far even with the very latest 3.1 update (the one with the new tegra bootup logo), the lag is still there..i am hoping 3.2 would address this...it sucks that you cant really play 1080p or even 720p smoothly

You're either doing it wrong (possible) or confusing judder for 'smoothness'. Files encoded at sane bitrates play back fine in 720p and are completely smooth. Unfortunately, as described by sontin earlier in this thread, there is some poor telecining going on in the hardware decoding and panning shots tend to create the effect of judder which can be somewhat distracting.
It's unfortunately probably a result of the lack of a NEON MPE core in the Tegra 2 chip that causes this.
But for the record, judder ≠ lack of smooth playback.

well i guess you're right, its a judder then, but if that's the case, is there any way to solve it? i want a perfect playback like what i get on a pc
I do feel though that playback has improved considerably with the last update. I have downloaded some files that were encoded specifically for the Apple TV and other such devices. Basically mp4 with [email protected] encoding with bitrates around 3000 kbps and stereo AAC sound. Before this update, every now and again they would freeze for five seconds or so, especially in high action scenes. Now they seem much smoother. Judder is still there, but it's definitely watchable.

You're either doing it wrong (possible) or confusing judder for 'smoothness'. Files encoded at sane bitrates play back fine in 720p and are completely smooth. Unfortunately, as described by sontin earlier in this thread, there is some poor telecining going on in the hardware decoding and panning shots tend to create the effect of judder which can be somewhat distracting.
It's unfortunately probably a result of the lack of a NEON MPE core in the Tegra 2 chip that causes this.
But for the record, judder ≠ lack of smooth playback.

Nothing to do with telecine. It only occurs when there is audio in the file. Mux a video with no soundfile embedded and it plays buttery smooth. Something occurs when sound is added which causes a weird juddering effect. It's been suggested it's hardware acceleration not being enabled causing it but I'm not so sure. Jitter can happen when the audio framerate does not match up with the video framerate to the refresh rate of the display or somesuch (Not sure on the technicalities). It's why tools like ReClock are used on PC's.
I can only repeat what i said a few times: The only way to get nearly smooth playback with hardware decoding is using a flash player. There is no other solution.
And there is a positive sideeffect: Using the browser filesystem (file:///) makes video streaming over the network more useable than using a file manager app. Even over HTTP (thx to drivedav and co) it's much better.

yes, you're right. with jwplayer it works perfectly, smooth and no judder!
Interesting
for those of you that are interest!
This is what i have decided to do and its quite amazing results for its purpose!
Previously i had ben encoding mp4's with x264, @ 1280x544 or 600 whatever the video wanted to strech too, i was finding amazing quality even at fullscreen! I was amazinly happy with respectable file sizes
The dark knight 2.3gb
Saving private ryan 3.5gb
Quantam of solice 2.6 CB
However, after my huge success! I wanted to accomplish more! I need more videos on my transformer! I felt ripped off, i could not put more videos then what i had becuasw of the file sizes!
After some trial and error i found an amazing discovery but it comes with some sacrifice,
Let me talk about the file sizes first!
The dark knight 1.1gb
Saving private ryan 1.6gb
Quantam of solice 1.2gb
The hangover 880mb
Some of my movies are under 1 gb wow
I have 27 movies on my sdcard alone! Which is great!
Ok so this is how i managed such small files with mp4,x264. First off i started my encodes by dropping the resoltion from 1280 to 800 and then letting handbreak decide how to strech it
800x544 is what it normally looks like, the quality is set to 21! This is an inferior resolution for filesize with mp4! In some cases 60% filesize drop!!
This comes with a small drawback! I run my videos in the stock player anyways, so they will not be fullscreen movies! Myself i dont mind the bars on top and bottom!
If this bothers you, then this discovery is not for you!!
MKV FANS!!
STOP!! , before you start to lecture me, about mkv ,doing higher res, with 500mb encode's ! just stop!
I undersand, and know how as well , but its not supported properly right now ,and thats not what im discussing
I hope someone finds this useful
Thanks
I don't want to reencode anything. I just want it to play my existing MKV's without juddering. How do I use file:///??? to play my existing MKV's with the Flash player?

Where can you get jwplayer - I looked in the market place and found what I am quite sure was not the tool that you meant...
