Hey all.
So the HTC Touch Diamond has a VGA screen. How can I get it to play VGA quality videos? or is this not possible? I would of thought it would be with its own graphics processor and decent cpu. I have tried .mp4 at 512kbits 640x480, but struggle more than 7 or 8 fps. It works good enough at half the resolution, but is still dropping some frames. Not as good at video playback as some reviews would have me believe.
I am using TCPMP , which has been modified to work with Windows Mobile 6.1
Many thanks.
Gary.
Well, I have played some movies that have higher resolution than 640x480 with -very- smooth framerates in CorePlayer (easily over 20 fps).
Specifically: HellBoy Sword of Storms, Eagle vs. Shark.
No problems at all.
HTC Touch Pro.
Yep, i have high res files playing in coreplayer as well (touch pro). coreplayer doesnt fully support diamond (or touch pro) so it can only get better in the future
Taken from Coreplayers site, this looks good:
GPU support: Intel 2700g, ->ATI Imageon<-, QTv, Marvell Monahan Processors
CPU Support: ARM9, ->ARM11<-, MIPS
Both the processor and gpu will be used really well on our diamonds/touch pros.
coreplayer works fine for me in vids much higher than the screen res, you must be doing something wrong or that "hack" to make the player work in 6.1 really isn't a good idea
Ok, thanks for all your replies. What format are you using to get decent fps with Coreplayer, and what bit rate normally?
Its a shame coreplayer do not have a trial version, so I want to be pretty certain first that it will work.
TCPMP hasnt been developed for a few years i dont think so that might also not help.
Well i splashed for Coreplayer anyway, but I still get rubbish fps
.AVI (xvid) 640x480, 24fps, 748kbits.
Am I using the wrong codec?

24fps!?
That's supposed to be quite good (100% for most movie rips).
Using Coreplayer, VGA .avi videos play very smoothly on my diamond as long as I'm not using A2DP. Once I pop on my Jabra BT8010, the high res vids start to skip a little. I hope Coreplayer fixes that up soon!
Hmmm, could one of you do a favour please?

Download the PSP version of the trailer, and then try to play that on your HTC Touch Diamond. It won't even play that for me Then let me know if it works fine for you or not. I get alot of tearing and skipping. I have gone as low as 640x480 avi at 512kbits and its still jolting around and skipping. I have used all the different types of rendering, and currently have Coreplayer 1.25
Not the good playback I was expecting
Thanks
Gary
After some tweaking around with the bitpool and some searching, I've gotten the A2DP performance hit down to a minimum.
Bitpool: 58
Maximum Bitpool: 80
That seems to reduce the stuttering when playing VGA vids using coreplayer. They still stutter a little during some demanding action scenes when using A2DP, but the stutter is much better and the audio and video are in sync.
Once Coreplayer is optimized for the Diamond, this thing is going to scream!
Overall, I'm pretty impressed with this little phone.

What version include this ?? or is just for a future version ??
And what is the GPU that comes with diamond ?? that "ati Imageon" ??
TY
So there are no video apps that are currently programmed to use HTC Touch Diamonds fancy bits? like the graphics processor etc?
use the divx labs divx player!!! lol

OK, I did what you said and I ran the video in Coreplayer benchmark mode. The best I could get was 70%. Perhaps it's the h264 format that is so demanding?
The more I use the Diamond the more I get dissapointed.
Hi, I'm having the same problem on my Touch Pro (i'd post in the TP forums, but no app/software category there), however I don't have Core Player because I won't pay for something if I can't see if it works first.
My question though is: Are there any similar movie file players like Core Player that are free?
(sorry if this was a bit off-topic, and I've tried searching but did not find anything useful)
If I see correct, madagascar is h.264 coded. It's a codec that is used to prepare hd video(b-r,hd-dvd etc.). It needs a powerfull processor or a hardware acceleration from graphic card. Some of new computers have problem with decoding it (i.e. with embaded video chip) and you're trying to play it on diamond. The 70% you're getting is a great score.
I have Coreplayer v 1.1.0 Build 1408
I get some lag for my music videos I have on my phone.
File Size: 78,924KB
Video Size: 640 * 480
Frame Rate: 29.970
is there a reason why it's laggy?
Why don't you try the latest build which is v1.2.5 I believe.

Just updated and still has the same problem, maybe it's the file that is the issue.
Hi,
I'm not sure who of you is familiar with the GPU accelerated video encoding, but both nVidia and ATi have some tools about that. As an owner of nVidia 8800GT video card I tried the Badaboom Video Converter and it works as a charm. I get like 120fps transcoding a 720p x264 mkv video to 640x360 mp4 h264 in the right format for X1's windows media player.
Of course when playing the converted video on WMP it is hardware accelerated by the videocard of X1, so the playback is very smooth.
In case you own some GeForce 8xxx, 9xxx, gtx 2xx VGA, you can download the trial version of the converter and test it for your own.:
http://www.nvidia.com/content/graphicsplus/us/download.asp
It works much faster than the HTC Video converter. I can tell that my 8800GT is roughly like 3 times faster for transcoding video than my Core 2 Quad Q9550 CPU.
I know Badaboom and have used it till 2 or 3 months.
Badaboom isn't really much faster than different encoders like SUPER. The HTC video converter brings much more quality because there is 2 Pass Encoding in using.
cemetry
Yep, you are right about the 2 Pass encoding by the HTC Encoder, but I can't really see any difference for the same kbps on my X1. In theory there should be, practically it's barely noticeable on such display like the X1's.
I haven't tested SUPER, but if it's not GPU accelerated it should be 2-3 times slower at least than the GPU accelerated encoder, and this is with fast CPU.
Did you use Badaboom with GPU acceleration? On which card? I'm curious how will one GTX 280 compare to the transcoding speed of an old 8800GT.
I would like to try this video converter, but your Link to badaboom doesnt work
Edit googled it, found it, http://www.nzone.com/object/nzone_badaboom_downloads.html
Have you experimented with optimal bitrate, and which device selection is best for the X1 ?
Badaboom can do the quality like the HTC Converter (btw. I've seen that badaboom sometimes draws artifacts), but the size of the video is much larger. Don't know what settings I had used, but I've converted a video with badaboom and the video had about 600 Megabyte while the HTC Converter has made only about 400 Megabyte and the quality was a bit better.
SUPER doesn't support the CUDA Engine and the speed is like Badaboom. Maybe I'm making a comparison between this 3 converter (maybe 2, because SUPER also uses x264 Encoder that the HTC Encoder used)

I'm not gonna worry about that. For Touch HD, I used Total Video Converter, I used Iphone H264 MP4 best settings and play in Windows Media Player, even in Touch HD it is smooth and stunning at full 800 X 480, only that scrolling through time frames or during video startup is sluggish. And for HD2, I believe the loading time will be shortened.
Playing high quality videos have been non issue with these HTC devices, you just need to do it right.

If you don't mind wasting time on conversion, that is.
From HTC website: Video supported formats: .wmv, .asf, .mp4, .3gp, .3g2, .m4v, .avi

Touch Diamond2 specs also mention .avi, but it's a half-truth. I use a Topaz ROM on my Touch HD and can't view regular DivX/XVid videos with anything built-in. Maybe the FullScreen Player from HTC Album (or Windows Media Player) here can play .avis with some weird codecs, but it's absolutely irrelevant to real-life scenarios.

Then we probably have very different HDs because mine reminds me of the era of 200MHz HTC devices. Playback of unconverted is jerky with visibly very low FPS, dynamic scenes are more like slideshows than films, even with 700MB rips, 1.4GB ones are even worse. This is not to mention that CorePlayer doesn't support AC3 audio which means that half of the movies I have are mute. If this is called being "very adept at handling" then I don't know what isn't.
Stock ROMs are exactly the same in terms of video performance, the reason why I mentioned Topaz ROM is simply because that device boasts .avi support, which it is in fact lacking. That said, ".avi support" is pretty much a meaningless phrase since .avi is just a wrapper, there could be a full zoo of codecs inside.

In what way do you imagine that these devices will be superior to the HD2 when it comes to video playback? If the HD2 can play back video at full screen resolution (800x480) with no dropped frames at all and support any wrapper or codec you might want, how much better can any other device really get? That (most likely) is what the HD2 running Coreplayer will deliver.
The only time there's likely to be an issue is if you expect to play back a high-definition (e.g. 1280x720) video downscaled to the screen resolution in real time. But, even if it's only for reasons of storage space, you'd probably want to downscale any clips like that to 800x480 resolution anyway.
It's possible that other devices (the ones that can use GPU acceleration when playing xvid and divx stuff) will offer better battery-life during video playback, I guess, but I doubt it'll be that big a margin.
Shasarak, it's not clear how the downscaling will work performance-wise without GPU support, and CorePlayer doesn't support AC3 sound. Not that I need to listen to AC3 on a phone, but I certainly have movies with it. So at this moment CorePlayer is definitely a mediocre solution as far as I'm concerned.
Shasharak,
Am not arguing that the device hopefully might be able to play, by CPU power 480p, but what about HTC not delivering for once again, what our money worth.
If u search for comparisons of omnia and any htc 528 based model, you will see great differences on video playback. This is unacceptable from me.
And what about gaming or 3d accelerated apps. We are getting to a new age of handheld devices, that should be (MUST BE) able to deliver video, web, audio and entertainment. And should do it with all their power.

Well, as I say, I don't imagine anyone will want to downscale video on it anyway - HD video won't look any worse if it's downscaled off-line, and it will take up far less space on the memory card than the original HD file.
Coreplayer not supporting AC3 is a problem, I'll grant you. It's possible that Coreplayer version 2 will support it. If not, then you'll have to see if you can get TCPMP running on the Leo - I expect there will be a version that does.

Yeah, but that's the point: you won't see those differences on the HD2. I own a Touch Pro2, so I understand how annoyed you are. But the difference with the HD2 is that the CPU is so powerful that it should be able to play back anything with a resolution of 800x480 or less without dropping any frames using the CPU alone - why would you care if it's using the CPU or the GPU if you can't see any difference in the playback? The Snapdragon CPU is nearly three times as powerful as the one in the TP2. Even without GPU acceleration it'll still work just fine.

Well, we know from existing benchmarks that the Leo will deliver hardware-accelerated OpenGL ES, so that's a good start. On some 3D benchmarks it's more than 20 times as fast as a TP2. (I doubt there will be any 3D-accelerated apps for Windows Mobile, anyway - otherwise people who own cheaper, slower WinMo phones will buy them and then complain they can't run them. WinMo apps tend to be written for low-end hardware.) Web should be fine - especially once we have a version of FlashPlayer 10.1 which will be in beta before the end of the year. I wouldn't worry.

I, on the other hand, can't imagine why anyone would want to convert any videos to watch on the phone. I have a notebook with a 60GB SSD and some 1.16GHz processor - it's blazing fast for Office/internet use but it'll take forever to convert any videos. I also store files like videos on a network drive, so using the more powerful desktop is still slow. And I need to watch videos only occasionally - when going on a trip I can copy a movie or two to take with me on a plane. So space isn't a problem really while ability to watch unconverted video is.
In any case, there was a question you asked about how another device may be more powerful in video playback - I guess with proper driver support they can be, and there are use cases when this is important.

As a TP2 owner with a slow desktop PC I feel your pain, I really do. I'm simply pointing out that the HD2 won't suffer from this problem to anywhere near the extent that current-generation HTC phones do. My best guess is that no video clip that runs at 800x480 or lower will require conversion; it's only ones in higher resolutions that will. And the chances are that even your netbook wouldn't be able to play a 720p video smoothly, so what use is it to store the videos in hi-def format in the first place? You might as well download a lower-res version.
If you end having to convert something very occasionally then just leave it running on your desktop PC overnight - it's not that big a deal.
The key difference, here, is that a TP2 can't even get close to playing a 624x351 xvid clip without conversion, while the HD2 will play it perfectly. It'll play anything other than high definition clips perfectly without conversion - so there is exactly one use-case where GPU acceleration is relevant, and it's not an important one.

It's not a netbook, it's a "real" notebook, Thinkpad X300, but anyway - I don't watch movies on my computers - I use a network media server and a network player, they are streamed to my TV. So my phone is the only computer-like device that needs to be able to play videos, actually.

In fact, I try to avoid downloading HD videos whenever I can as I don't care for viewing them in high resolutions even though I have a large Full HD TV. The problem is only that low-res versions aren't always available, and increasingly so. It's not my preference but rather an unfortunate trend.
So you think that the snapdragon "RAW" is enough. Enough for what ? There are no limits for what to expect.
Should HTC, continue to ignore what GPU means, we should not. once again accept it It was like 2 years ago when I complained about my TC performance, without getting any answer. And now Samsung, on their first winmo device (omnia), has really better results, using the same processor. There will be tons of snapdragon devices, or even tegra powered (hopefully) soon enough.
If Qualcomm refuses to give the guys who write CorePlayer access to their intellectual property, that isn't altogether HTC's fault. Any software actually written by HTC does use GPU acceleration - there's a limit to the extent that they can be held responsible for the deficiencies of third party software.

I set down very precise limits in my prediction: CPU-only video decoding will (IMO) be adequate for all videos with a resolution of 800x480 or lower. Any video with higher resolution may require transcoding - but it obviously couldn't look any better than an 800x480 video if it's being played back on an 800x480 screen.

And how exactly should we "not accept it"? I am also pissed off at HTC, but I don't think we can do anything except buying something else, but there are also reasons not to (all of them very individual).

True, with a BUT: they (HTC) could enable their software to play real-life video formats. Samsung's Touch Player does that. And a smaller "but": they could also provide generic driver that would provide DirectX/OpenGL interfaces for Qualcomm's quirky technologies. Both options would cost them money I guess, so they chose not to.
What are the specs of your computers and how long are your average encodes taking ?. I'm looking to buy some new gear soon so I'm just looking to find out how fast the encodes can be.
I have over 100 720p films to convert so its gonna be very time consuming.
they'll probably just work if you use moboplayer
Well. if you have a core i7 then it shouldn't take too long.
I have an i5 750, ati HD5850, and 4GB of RAM. Video encoding is the only thing that maxes out all four cores on my processor, and it takes about one minute per six minutes of video on average using handbrake. However, I don't bother re-encoding videos anymore. I just use plex, but that might not work for your circumstances.
Whatever you do, make sure you encode baseline h264.

@OP
Get a quadcore. Otherwise, it doesn't matter all that much. This, from one who has xcoded thousands of movies & movie clips on a bottom-end dual-core.
It matters more how you're encoding, and what software you're encoding with. x264 has different speeds, and unintuitively, 'fast' speeds can get a smaller size than slower ones.
Resolution makes a big diff. Many think 1280x720 is best for tablets. The truth is, there's very little quality difference between 1280 and 800 on a small screen, and the 800 res is about half the size and xcode twice as fast. It also streams much smoother over wifi.
Ignore the peeps who said you have to encode to baseline profile. The 3.1 update apparently can handle high profile now, although it still doesn't have native MKV/AC3/DTS support. I would try high prof first, then main prof.
Lastly, it only takes a long time if you sit and wait for it. I'm doing a 21-CD miniseries to MKV, and before that a 95-eps series. Each job takes me about 10 mins to set up, and some extra for spot checking. Otherwise, just let it run and ignore it.

I know high profile has worked fine for SD content, but are you actually getting smooth playback on high or main profile 720p?
Edit: I just tried a few that I had that happened to be high profile with aac audio, and I'm still getting pretty choppy playback but it IS better than it was in 3.01. I'm still curious to know whether you or others are getting better results here, though.

I have an Intel i7-2600 with 8GB of RAM and a Intel SSD for my machine, and a 1.33hr 720p rip of Restrepo takes 30mins to encode using the attached Handbreak preset (rename to "xoom 720p.plist" and import). I think I got this from XDA but I can't remember, and it works nicely for HD content.
I also use Moboplayer as it's the only one that seems to work without issue.
I have an i7-950, 12GB DDR3 (XMS3) and GTS450, on an Asus ROG III Gene. Can convert a blueray with handbrake in under 20 minutes and a DVD in under 15. And I always write the output to a different physical hard disk.

Cool, downloading your clips now to see.
I'm looking for an application which supports h.264 encoding on the Tegra 2. My desktop PC is just way too slow at re-encoding and the fans get too loud to leave it running over night.... so I thought I might do my re-encodes on the TF itself, but so far I haven't found an application which supports this. Does anyone know if there is one?
I haven't seen one but I have the feeling it would be horribily slow...

This is Obviously going to be slower than realtime, otherwise you'd play the movie smoothly without the need to reencode.
Not sure why you would think the TF with a 1Ghz mobile chip and 1G ram would be faster than a desktop, unless your desktop is very old.

unless your PC is more than 5 years old, there is a good chance it will still encode h264 faster than the TF...
what numbers in fps you are getting if you use handbrake to encode H264 720p in High Profile? I have a rather beefy desktop with i5 2600k and it encodes about 65-70 fps, and my old dell laptop with T7200 runs about just over 20fps
I have a 2.8GHz Pentium 4 with 1GB RAM. From what I've tried so far my encoding speed hovers between 1-5 fps. So yeah, encoding on the Transformer can't be that much worse, and I wouldn't have to deal with roaring fans.
Tegra2 probably supports hardware encoding of h264 (for the camera for example) but apps won't have access to that unfortunately.
