so what i should change in coreplayer to best performance ony my HD ?
[Touch HD General] IceEyz:
Everybody here,

Take a GOOD look, at this thread, linked page, 3rd last post!

He's playing H264 at 1000kbps, in WMP!!.
[Touch HD General] m@rco:
Hi There,

Does this also works on the SE Experia X1?

Best regards, m@rco
[Touch HD General] razorblader:
I have tried a 560x304 h.264 file (from 720p mkv source) encoded with a bitrate of about 1000kbps and it runs amazingly well under WM on the HD. Currently I am encoding to 640x368 with a bitrate of 1200, audio AAC LC 128, let's see, how this file will do. Definitely something to check out, it looks like the algorithms of WM are not as strict as the ones of Coreplayer, I would not say it is totally smooth but very watchable. If the higher encoded file runs without problems there might be some hardware acceleration involved...but I kind of doubt it.

Hi Tnyynt ,

Top work my man.

I have a quick question if someone doesn't mind helping me out.

I've downloaded the SUPER video converter as you have suggested, however, there seems to be no sign of the FLV codec listed in the dropdown list. There is an FFV1, but I'm not convinced this is the same thing.

Do I need to download the FLV codec separately?

Any help would be much appreciated, cheers
[Touch HD General] jackthekayman:
I'm trying to playback an .flv h264 codec file, but coreplayer says that it doesn't support this codec, is it true?! :confused:
[Touch HD General] IceEyz:
I've encoded a few files myself, and have had others play it back, without succes so far.

To be specific, I'm encoding for the Touch HD since that's going to be my device, and have encoded mp4's at 800x382, under 1000kbps with AAC at a framerate of 23.976.

Soon someone will probably test my .avi version and one with a framerate of 25, and at 640x360, as well as different audio. Hopefully, we'll get to a setup that really works for everyone, everything and everywhere. BTW, How's the Xperia handling videos like these? It should be worse, or, if they have perfect acceleration in their panel, we need that.
[Touch HD General] dwaradzyn:
Good news everyone!

Next release of CorePlayer will have full QTV support! We should expect it to unleash Blacksone (and other Quallcomm based devices) potentials:

[Touch HD General] tnyynt:
No, just select swf or flv (Flash) in the container box and FLV codec.

Nothing new here!

Just don't get your expectations too high!
[Touch HD General] tnyynt:
I still wonder all those negative answer poll voters, what issues are you experiencing or what exact expectations do you have that made you all vote negative?
[Touch HD General] DANEMAN:
hi i,am one of the not just yet due the qualcomm video niggles but that will be sorted my kaiser/diamond had same probs so hoped htc would have fixed them by now but looks like coreplayer will help some of the flaws.other wise it,s the best on the market better than that fruit thing,,lol
[Touch HD General] tnyynt:
I'm not really getting it. Do you experience playback problems with my HD sample clips?
[Touch HD General] DANEMAN:
no play back probs ,but i now run my videos at 640x352 frame rates 29.970 no problems.
[Touch HD General] tnyynt:
That's all I wanted to know!
[Touch HD General] razorblader:
Tested this tonight with different resolutions, here is the result:

800x480 h.264 @ 1250 23.976 AAC 128 runs smoothly under WMP and looks absolutely stunning !! :)

WMP seems to run these h.264 AAC files with hardware acceleration !

Coreplayer without the hardware support absolutely chokes on the higher resolution files.

Resolutions tested were 560x304, 640x338 and 800x480. The biggest one is a bit out of whack as far as the aspect ratio is concerned but I wanted to use the full resolution of the screen.

The HD deserves its name after all, that's almost 480p running smoothly.

Will try to provide a link to the converted file tomorrow so you can see for yourself.
[Touch HD General] JardaBar:
Hi, here is my result for video:

Video: 640 x 352, XVID, 1.557 Mbit/s, 25fps

Audio: MP3, 133kb/s

Benchmark result:

Original playback: 78.19% (19.547 fps)

Tweaked by tnyynt: 86.65% (21.663 fps)

So, it helps, but not enough for tested video. ReEncoding is needed for typical video. :(

One way or another, many thanks to tnyynt!!
[Touch HD General] Philosoma:
I had a quick test with Super encoding that Transformers FLV to 800x480 MP4 and it worked quite well in Media Player. A few stutters though. In coreplayer however it benched 64%. Still, the real goal would be to just copy across any video format for playback.
[Touch HD General] tnyynt:
You can get far more better result with larger resolution and lower bitrate if you follow my finding regarding container and coder.
[Touch HD General] tnyynt:
You will never have that just like you can tune up your car's engine till you drop, it still won't beat a Porsche!

I think most people have a perception problem: it's a PDA not a PC, with more than 3 times slower hardware.
[Touch HD General] losdrivare:
Great find!

I was curios about about how h264 would perform, I had it back in my mind somewhere that the Blackstone would have acceleration for that.

Looking forward to see more results with h264. It would be great if it would be possible to re-encode true HD content to 800 width, proportional height and a suitable bitrate. I'm sure that would look awesome and with 800 width the device wouldn't have to scale and could concentrate on processing the bitrate instead. I used to encode video like this back in the day when I was watching movies on my Palm Tungsten T3... :)
[Touch HD General] IceEyz:
That's great :).

But what container and what specific options did you use?

If you could provide a link for all of us to test, would be fantastic!
[Touch HD General] hassan:
Yeah that would nice, if you could teall us that what baseline profile (1.1, 1.2, 1.3) you've used as well as the contanier. Also what encoder software you've used to encode the files. :)

-----------

Confirmed.

QUANTUM OF SOLACE trailer download from apple and encoded with Quick time H.264 baseline profile 1200kbps @ 800X430 works really well with media player.

Am gona try to encode other clips with Media coder and report back.

http://rapidshare.com/files/165644938/quantum_of_solace-tlr1_720p.mp4

Please only use media player to play the above file.
[Touch HD General] Philosoma:
Had more of a play. I done the first few minutes of 1080p Star Wars using baseline 5.1 (don't know what the differences are) at 1008kbps and 128 AAC LC and it is pretty damn sweet. Still need to work out how to crop it for correct aspect ratio without borders though?
[Touch HD General] hassan:
I've only tried baseline profile upto 1.3, could you please tell me what encoder software you used?
[Touch HD General] Philosoma:
Super. Link is on the very first post.
[Touch HD General] razorblader:
Sure, I used Super for encoding, container mp4, h.264, 800x480, BR 1200 kbps, AR 16:9, 23.976, AAC LC 128 kbps, h.264 profile: Baseline (cabac off) 3

Like I said in my last post, the AR is a bit off, the point was to use the full resolution of the screen. This is the chuck file.

There is a second file, converted to 560x304, 1000kbps, all the other settings are the same as above except this runs at 29.976 and has lots of motion in it. It's the mythbusters file.

The source files are 720p h.264 AC3 Matroska files.

You can find the converted files here:

http://www.mediafire.com/?sharekey=345639a8ffe662bad2db6fb9a8902bda

To play them smoothly watch them with WMP but you can also try Coreplayer, you might notice a 'slight' difference in performance.. :D
[Touch HD General] hassan:
Thanks for all that, atleast we have solved hi def video play back problem.

Now it looks like one killer mashine compare to other smart phones.

:D:D
[Touch HD General] tnyynt:
Isn't BaseLine (Cabac Off) and Main (Cabac On)?

How did you go for Main (Cabac Off)?
[Touch HD General] razorblader:
You're right, that was a typo (already corrected), it is BaseLine (Cabac Off). My bad. :eek:
[Touch HD General] dextergregor:
Please forgive my complete ignorance on this matter. But I'm a complete newby to coreplayer. I just installed it unto my blackstone (which was delivered yesterday). I've got one annoying problem though. The few videos I've tried on the coreplayer work, but there's no audio coming through. I probably have to do something to the settings, but I have no idea what. Can anyone please help?

Edit: False alarm people. Finally got it to work. Feeling pretty dumb right now ;)
[Touch HD General] razorblader:
You're welcome! I will keep tinkering... ;)
[Touch HD General] arfster:
Very nice. With a HD source, that's essentially DVD quality we're getting.

Also nice is that 1.2mbit is a mere 9Mbytes/minute. In 8gbytes we can fit almost 15 hours of this quality.
[Touch HD General] marcel808:
I followed razerbladers advise and tried a file

800x480 h.264 @ 1250 23.976 AAC 128

I downloaded a star trek 720p trailer, reencoded it to 800x480 and it does run very well in WMP. And its very slow in coreplayer.

I don't have tons of bandwidth but if anyone wants a copy to try PM me

Same performance in Coreplayer Benchmark with these settings. Maybe it has impact on other file formats.
[Touch HD General] Bilbo Fraggins:
Wow those trailers look great.

I have to say I was a bit disappointed after the appaling performance I was getting from BBC iPlayer video files but those 2 trailers have cheered me up :)

For those familiar with iplayer. Any ideas why the files it says to download for portable devices run so poorly? DRM perhaps?
[Touch HD General] mrn2012:
I have been trying to follow this, and I have installed Coreplayer and everything else mentioned, but I stll cant get the demos to play? Is there a setting that Im missing? Any help woul be really useful, suich as what files to install and what settings to use. Many thanks in advance..... Love this forum!!
[Touch HD General] razorblader:
If you want to play Tnyynt's files, they will work in Coreplayer, preferably with the QTv video option under preferences. For my files you don't need Coreplayer, Windows Media Player plays them just fine.
[Touch HD General] mrn2012:
Ok, now I understand. I was using Coreplayer to play the MP4 files and it didnt seem to like it. It played AVI's fine though. Many thanks,
[Touch HD General] razorblader:
No problem, at the moment Coreplayer can not make use of the hardware video acceleration of the chipset so it's somewhat CPU limited as far as video performance is concerned, thus this thread to establish what's currently possible. WMP seems to play mp4 h.264 files (and most likely the other video formats it's capable of playing) with hardware acceleration and gives better performance on higher resolution files.

The Coreplayer developers have already stated they will implement full hardware support for the chipset in an upcoming release of their software, it might be a while though.
[Touch HD General] El_Mariachi:
It's not possible to play .avi files in WMP though is it?
[Touch HD General] pzucchel:
Seeing the comment from tnyynt about the impact of cache it is clear that - somehow- our settings already differ, which is good for cookers - right? ;). Or, maybe, the benchmark doesn't tell the all story. Without increasing the cache, i get nominal performances under coreplayer benchmark which are good and confirm tnyynt numbers. But when i move to see the movie at normal speed....it skips every 10 seconds or so. This skipping has disappeared, almost totally, by increasing the cache size in my case.

It must be a non-obvious match between cache and bitrate, in my opinion, or effects of activesync/processes in background accessing the SD.

I get great results in this moment with avi/divx at 1200 kbs, and audio mp3 at 128kb/44100 KHz.

...good that we have some space to play&tune, and to have different opinions. Otherwise our blackstones would be already boring, isn't it?
[Touch HD General] razorblader:
After some more experimenting with h.264 mp4 and WMP here's my final verdict:

The best overall quality/performance ratio award goes to this format:

640x338 1200kbps mp4 h.264 23.976 112 or 128 kbps AAC for 16:9 content.

You can encode to 800x448 1250kbps but the quality difference on the HD screen is not really worth it, for (barely) noticable better quality the bitrate has to be higher which affects performance in fast sequences negatively.

560x304 1000kbps works great too and is a surefire way for encoding material that has lots of action in it, it even works very smoothly with 29,976 frames.

For resolutions higher than 560x304 I recommend to convert to 23.976 frames/sec even if the source is 29,976.

Apart from the settings above I have used the following parameters:

Aspect: 16:9, Options: Hi Quality, 48k Audio, H264 Profile: Baseline 3

Audio 48k, 2 Channels

For Audio you can use 44k as well of course.

I have uploaded three more sample files with 560x304 1000kbps, 640x338 1200 and 800x448 1250kbps so you can see the difference between the different resolutions.

You can find the additional files (entouragexxxxxx.mp4) here:

[Touch HD General] jyod24:
I agree in unison, so to all readers.. The solution is

1. Wait for HTC to come up with a update that allows its WMP to support more video format. Or even allow other 3rd party software to use its video acc. on its chipset

2. Wait for Coreplayer to come up with a update, probably 1.3, that allows CP to use the video acc. of blackstone

Either which we just have to wait with our finger cross. What if both situation, do not happen. Blackstone with be definitely do not live up its name as a MULTIMEDIA PHONE.Which i will want it to watch unconverted video files on the go.
[Touch HD General] Rizlo:
I tried both your 560 and 640 files and they both perform quite badly in wmp, and simply unwatchable in coreplayer... I have an unconverted video in 624x352, xvid, which performs WAY better, with core... and still unacceptable. We are far from an effective workaround IMHO.
[Touch HD General] tnyynt:
You never will!
[Touch HD General] Eraser85:
I'm unable to convert any video with SUPER. Everytime I try it gives me an error (very generic like try to change aspect ratio, check if you have the codecs and so on...)

Anything I should do or check before trying to convert a video?
[Touch HD General] JardaBar:
Aspect ratio 16:10

Recommended settings for video encoding is not optimal, I thing. Aspect ration of Touch HD screen is 16:10. Which means, that recommended video by tnyynt will be not played on full screen and using all pixels available on the LCD display.

I think, it's better to use 520x312 pixels, to get video player using all pixels of the screen.

Question: Have some one any exprerience about playing full 800x480 video?
[Touch HD General] hassan:
If you go back few pages on this thread, you will find every thing regard playing videos @ 800x480.
[Touch HD General] m2te:
I had fun and games with Super also such as virus warnings and a long start up time so I downloaded Media Coder 0.6.2 and I am very impressed with it-

http://mediacoder.sourceforge.net/

I have attached two profiles I have been using and have got good results with. They are basically the same (one bodged to supresses subtitles)-

MP4 H264/ACC

800x480

Baseline level 30

1000kbps video

128kbps stereo sound
[Touch HD General] Rizlo:
How can you be so sure? with this specs and hardware acceleration support from Core (although obtained by reverse-engineering) there is still hope I think. 1.2.5 with Qtv, native colors is already delivering a result similar if not better than re-encoded files on WMP! I also tried medium quality on CP and all the skipping is gone. Too bad the image gets almost destroyed....
[Touch HD General] kisstom:
wmp does not play your sample files at all...

????

Any idea
[Touch HD General] Rizlo:
What do you mean it doesn't play... do you have an error message?
[Touch HD General] Insaneboy:
HD files you probably won't.

But SD files are playable even now, and they can only get better with hardware support, that's enough for me.
[Touch HD General] dcoales:
I have a problem with these files too. I downloaded the entourage files, opened media player, selected "open file" navigated to my storage card, selected one of the files, hit play and nothing happens. Media player freezes completely. If I go to the task manager media player is then not even shown in the list of running tasks. The only way to then get media player to even start up again is to soft reset. What am I missing here - are people renaming the files or changing any media player settings before running them ? Interestingly, although I have copies all three files to my storage card, only two of them show up in the media player "open file" dialogue.
[Touch HD General] Rizlo:
If they all have the same extension they should show up.... don't know what to say, sorry.

@Insaneboy: SD files are playable but still skip a lot... I just can't live with that! For true HD files, there's no point in exceeding your device's native resolution, which is already incredibly higher than your PC's screen. Have you tried looking at a sceen capture from the Blackstone on a monitor? It looks huuuge :D
[Touch HD General] kisstom:
Yes, it says cannot play the file (mythbusters_sample)
[Touch HD General] jackthekayman:
I think this way too, maybe it will not never possible to play 720p file
[Touch HD General] Rizlo:
Our goal should be 480p, anything above is totally OTT.
[Touch HD General] frustin:
Why do my files after being encoded (using SUPER) end up bigger than the original?

Can you post a screen grab of your SUPER dialogue please tnyynt?
[Touch HD General] benolit23:
Well, that's possible. If you reencode your file with higher bitrate

than the original, you got bigger file.:D
[Touch HD General] Insaneboy:
Depends which file.

I got two at 624x352 24fps 1100 KBit/s and they play ok.

I also have some at 1700 which stutter, that's what i'm hoping will get fixed with Core Player 1.3/2
[Touch HD General] Rizlo:
"Standard" 350 megabytes tv episodes? That's what I'd need to watch without re-encoding...
[Touch HD General] jyod24:
When i mean unconverted videos, i simply means videos of such stats:

624x352,

Framerate: 23/s

Data rate: 1131kbps

video compression: DIVX

If Blackstone cant even play this smoothly, i don't think it is worth our money on this phone anymore.
[Touch HD General] tnyynt:
Just to make it clear: it's not a hardware problem when referring to this specific issue. HD will play back those videos a bit choppy while it would play back even higher res videos in other formats just fine (i.e.: FLV). It's got something to do with decoding them. It's just the same as the decoder issue in Coreplayer playing back choppy MP4 while WMP plays back just fine.
[Touch HD General] frustin:
Can you post a screen grab of your SUPER screen please, tnyynt?
[Touch HD General] tnyynt:
Here you go!

​
[Touch HD General] dcoales:
Just out of interest I tried encoding at 800x480, 500Kbps video, 128Kbps audio, h.264 encoding inside an mp4 container, 25fps (ripped direct from a DVD using a shareware package called DVD Catalyst).

The result is better than the divx encoding I was using at 700Kbps when played back in Windows Media Player and the file is about 200Mb smaller of course.

I was interested to note that if you double tap the mp4 file in file explorer then the movie opens in the same player that is used in the youtube application. The playback is as smooth as with media player but I prefer the UI (it automatically launches in landscape mode and stays in landscape mode when you tap to bring up the controls). I think this is the Album application player.

Cheers,

Content of TNYYNT SD cab

Hello Tnyynt - nice to see you again (your trinity roms are still in my heart!).

Could you please comment on the cab you attached in the first entry of the thread - i understand you are somewhat increasing the cache size (4096Kb) but i didn't compare the other keys with a standard configuration. What's the actual modification? What's the actual improvement you expect? should it appear only for "high" classes or is it a general improvement? most of the HD users have a class II, at least this is the microSD which i found in the box.

thanks indeed,
[Touch HD General] tnyynt:
Nice to see you too, pzucchel!

Keys added are not present in stock ROMs, afaik. It basically enables DMA and sets caches.

It should work on any type of card.

Results expected and proved: 3-4x faster card access and transfer rate.

As I always said: run an SD Card speed test benchmark, install my cab, run it again and compare. :D

P.S.: Users from other devices may not benefit from speed improvement if they run cooked roms, since Chefs already set these values in their ROMs, so target devices are stock devices, just as our Blackstones for now.

Hope I cleared everything!
[Touch HD General] rovex:
Im using super to encode, but different settings.

MP4, MP4/AVC, ACC LC

800x480, 23.97FPS 912kbps

Audio bitrate 64kbps.

These settings play nice and smooth and quality is fine. If im encoding a 4x3 video i'll use 640x480.
[Touch HD General] tnyynt:
To be completely honest, you can't see any difference in quality from 640 pixels up.
[Touch HD General] rovex:
Im more concerned with the 480 than the 640 or 800. I want to maintain the native resolution as much as possible thats why i see 800x480 for windscreen or HDTV movies and 640x480 for SDTV sources.
[Touch HD General] tnyynt:
Instead of 800x480 use 640x384 and instead of 640x480 use 560x420.

You won't see any difference but you will gain space and performance.
[Touch HD General] rovex:
If you're converting lower quality sources yeah thats true, but if you are converting high definition sources then you really can see the difference.
[Touch HD General] tnyynt:
No you can't but I'm not going to argue!
[Touch HD General] pzucchel:
Hi Tnyynt - in fact i was too lazy to run it before, now i have it installed by default and so i was wondering its actual impact (it works very well and i have nothing to complain - actually TotalCommander looks to have a faster access. In addition, i am keeping a very large cache (32Mb) and i made the system smooth by removing one replog activating activesync on time changes. If you see the thread on the "freezes", i am afraid that the same effect has of course an obvious effect during playback. I see a noticeable difference in smoothness....I tell you this for your next ROM ;)
[Touch HD General] rovex:
Lets just say you cant, i can..
[Touch HD General] frustin:
