So I've done pretty thorough research into the ins and outs of the video problems with the tilt(kaiser). I get that the inadequate drivers slow everything down (the time it takes for my tilt to go from portrait to landscape is ridiculous). But I have an question that I can't seem to find an answer to:
The videos rendered using youtube, or really streamed from any website, do not suffer from any kind of lag, buffering (unless I'm out of range), or any other ill effects. The clearest and sharpest videos I get are from online streaming. Why is that?!? Whereas videos I upload from my laptop, or especially videos I record on the phone are completely, absolutely, so awfully unwatchable!
Is it just a matter of video size and quality? If i reduce the video recording resolution would that help? (the answer is no, i've tried).
More importantly, is there a way to replicate the streaming videos a la youtube with the videos uploaded or recorded on the phone?!
While I don't have any hard facts to prove it. I belive the issue lies in the resolution and audio quality of the youtube videos. I Watch youtube on my phone with no problems. but the quality is Vastly lower than the videos I upload from my laptop. If you reduce the quality of the videos you upload you'll notice a similar speed boost. but you'll be reducing the quality quite a bit.
At least thats my experience. I notice a better playback when I reduce audio and video quality of my files. But considering I need subtitles for what I watch. Quality reduction isn't an option for me.
What programs are you using to play each of these? Also, streaming videos will almost always be a lower resolution thatn files from your computer. A streaming file can have a large enough resolution that it looks very sharp on your 320x240 screen, but not sharp on a desktop monitor. Now, the file that looks good on your desktop monitor at a resolution of 512x348 or so, requires a lot more CPU to render, thus looking like poop.
It makes sense that youtube etc videos are of lower resolution and everything. But I would honestly take the lower resolution if I could have not-jumpy streaming of the videos i record. Is it possible to tweak my cam in some way to make that happen? I've tried setting it to the lowest resolution but that doesn't work. Any other thoughts on this?
while resolution is important matter ...
stored medias can have different bit rates (kbps) this applied to both streams and stored/recorded media...etc and don't confused this "KBPS" with the rate of internet speed ... 2 different things ... too high a rate will choke your device
select one stored media and choose properties ... click on the summary tab ...check it and see !!
you can have 2 videos with the same resolution ( X by Y ) ... but concentrate on bit rates ( kbps ) as well as frame/sec ( fps )
out of the 3 above ... resolution is the least important ... as our device is QVGA ( 240x320 ) ... if your media is higher res ... it will shrink to fit ... likewise, if it's lower res. ...it will stretch to fit ..etc
ie ... try playing a 640 x 480 video on a modern desktop monitor ( which is averaging 1280 x 800 ) ... and it will still play fine ... but stretched ....therefore, that is the LEAST of your problem
Is anyone having problems with video playback?
WMV files they are played very slow (loosing a lot of frames). With MP4 I got best results but not the best. Any suggestions??
Thanks
WMV
I can't even get the above files to play
are you using Media Player? as video playback has always been awful on Medial Player on every pocket pc or smartphone ive everhad.
install TCPMP and video playback will be perfect, and will play any file you throw at it

Thanks for the tip keyz86. I'll try it.
no problem, glad to help a fellow Dimondarian
won't play
loaded the TCPMP but everytime I try and start it i get the attached error, using diamond help

Dimondarian Cool hehehe
Has anyone been able to play a full resolution file without skipping?
I am using CorePlayer now but if another player works better, please say so.
With Coreplayer I benchmark about 85%, which is not good enough.
I believe the Diamond should be able to get 100%.
I found that an encoded mp4 file would play about the same as the original avi xvid file...
What do you use to encode videos specifically for the Diamond?
Come on!! Post your results!

What video settings do you use with coreplayer ?
DirectDraw, GDI or what ?
This is what i get:
With these configs.:
But with some other videos i have i get only 88% speed and some frame drops and tearing.
Doesnt the Diamond has a good video hardware.
Imo, it shouldnt lag at all.
Ive read somewhere that it doesnt use the hardware correctly since the drivers were not fully implemented. Not sure if its true.
Still looking for a good solution... any more help?
Coreplayer is still choppy ...
Yeah, I wasn't able to get WMVs to play using this, either.
I think what we need to have a look at is which encoding, resolution, bitrate, fps, etc are optimal for the diamond using core player.
I'm experimenting a bit. Will report back in a bit...
I've just got my Ignito (diamond) a couple of days ago, but I've got a long history of video playback on hand helds. Since this is my first time post, and I happen to have a bit of time on my hands.... I'm going to convert a file into a series of different resolutions and settings to see which one will perform the best. I know the objective is to get a full res one to play, but I'll see what I can come up with.
Also, I'm using the default ROM at this time.
With Coreplayer you should use the 'QTv' display option - this is hardware accelerated and beats 100% benchmark on every AVI I have tried. If you get a blank display using this mode, you are using an old version and need to update.
Alright. After trying a bunch of different codecs, encoders, video and audio formats at various resolutions I came the conclusion that for now, full resolution video is just not possible without jerky movements during continuous motion or fast action scenes.
My eyes are very sensitive and I get really irritated if playback is not perfectly smooth.
So far what works the best in achieving this kind of natural playback is AVI as the output container with XviD video codec at 480 x 360 resolution, and mp3 audio. I set the video and audio bitrates to match whatever the source video was (min 864 kbps and max 1008 kbps for video and 192 kbps for audio).
Even then, CorePlayer is a must with the following settigns: QTv On, TytnII driver mode On and Smooth Zoom On.
Every now and again CorePlayer will show only a purple screen during playback when QTv mode on. At that point I usually do a soft reset and it starts working again.
This issue may be resolved with an upcoming release of CorePlayer (1.3) but until then, the solution above works exceptionally well.
I'd be very interested in anyone else is having success in other ways...
320 by 240 versus 640 by 480
I have done some playing with conversion and have found that the Diamond (currently) does not support the 640 by 480 settings with a good bitrate. The BEST conversion I have found (using Coreplayer to play back the files) is using the BETA Version of the Pocket Divx Encoder (http://www.pocketdivxencoder.net/EN_index.htm) and using the HTC Diamond Template (NON VGA!!!!, there is a VGA and non VGA) that team has developed. They have done an excellent job!
The output settings -
Dimensions 320 by 240
Video Quaility - "36" ... 584 kb bitrate
Hopefully an update by HTC or coreplayer will be released to fully utilize the resolution that the Diamond SHOULD be able to support, but for a clear, non jerky playback, this is my 2 cents
im able to play those axxo dvdripson using coreplayer without any sort of convertion....
I want to share my experience. I am using core player and trying to recode unprotected high-definition TV shows (original resolution of 1920x1080) that I've recorded on Windows Media Center (.dvr-ms files) to watch on my Sprint Diamond. Unfortunately .dvr-ms are poorly supported, and the only program I've found to recode is TMPGEnc 4.0 Xpress.
I am using Core Player version 1.2.5 build 4506, and my video output is QTv Display with the Tytn II driver mode enabled.
Like everyone else here, I have had horrible results when converting the shows to DivX at 640x360 at any usuable bitrate (above 500 kbps). Benchmarking in Core Player yielded a playback speed of 66% or so (completely unacceptable, obviously). So I played around with the resolution and bitrate, and finally settled on the following:
Format: DivX
resolution: 512x288 (maintains the 16:9 aspect ratio of the original)
Video bitrate: 850 kbps
Frame rate: 29.97 fps (progressive)
Audio: MP3
Audio bitrate: 80 kbps, 48kHz sample rate
With those settings, I have a 104% playback benchmark with around 25 dropped frames compared to several thousand played, and about 29.5 fps. Basically, it is completely smooth audio and video.
I was still PO'd that I had to sacrifice so much resolution and bitrate on a supposed media device, so I played around with other formats. WMV was awful. MPEG-2 was awful, and avi was passable, but no better than DivX. I also decided to try h.264 (MPEG-4 AVC). Here are the settings I used:
Video Format: MPEG-4 AVC (saves as .mp4)
Resolution: 640x360 (still maintaining the original 16:9 AR)
Video bitrate: 1000 kbps
frame rate: 29.97 fps (progressive)
Audio format: AAC
Audio bitrate: 96 kbps, 48kHz sample rate
Core Player absolutely choked on this. It was unwatchable, and the benchmark revealed a playback speed of 50%. Dropped frames were higher than played frames (!) and framerate was 13 fps. Obviously not successful.
But, before I deleted the file, on a whim I decided to try Windows Media Player and...it was completely FLAWLESS playback. Absolutely beautiful, smooth motion, no audio stuttering, slow and fast pans were the best I've ever seen on a WM device.
Why??? Is there something I'm missing about this that someone can elaborate on? Is this the fabled "hardware acceleration" that I've read so much about? I should note that WMP had a hard time on a 320x240 .wmv file, so I can't really understand how it is able to play a 640x360 .mp4 file so smoothly. In any event, I have found my perfect file format, and, surprisingly, it doesn't involve Core Player in any way.
-R
The thing is that HTC didn't release any kind of SDK for Diamond or Touch Pro and companies like CoreCodec have hard time trying to figure out how to use the HW acceleration but they are trying very hard to improve the situation so maybe with time they will be able to use the HW for now the only way we wan't to watch videos with HW acceleration is only WMP which means recoding or atleast remuxing files.
Cheers
P.S. Could you post exact specs of the .mp4 file? What kind of AVC it was and things like that.
in regards to the WMP hardware acceleration.
is it better on battery life than having coreplayer trying its hard out to render a video. even if its a small 320x vid that plays at 120%. Does that mean that the cpu is running near max?
I made a new video with myself with my Samsung HD Camera. It records with 50 FPS and in 16:9 - 1280x720p. I was wondering what the best results would be to convert to for the Touch Diamond. If I choose 25fps from 50fps originally, the video doesnt seem smooth enough.
And if I just choose to make it, say 320x180 and 50 fps at 1000kbit, it lags alot on my phone. What can I do? Its coded with WMV 9 codec.
Try to encode with 30fps, and 640x480 wmv9 WITH hardware acceleration (search for video encoder on forums )
Hi! I did some video and I noticed that their size is excessive.
I recorded a video of 02 minutes and 52 seconds and its size is 200MB!!! I don't think it's normal but, anyway, I was looking for a method/software that is able to compress the size but keeping quality on pc. Have you one to suggest? Thanks in advance.
Well one idea is that you can go to /etc/media_profiles.xml and edit the "bitRate" line under the 720p encoder section and reduce it. This will reduce both the quality and size of the video while recording.
If you want to compress a video on your computer, use something like AutoX264. It uses the x264 codec like your phone, which is currently the best video codec (x265/HVEC out next year), and is easy to use.
AutoX264 give me an error with all codecs (ffmpeg, mencoder ecc..) it seems that it cannot retrieve video's filesize information. Is there a software less complicated and more "auto"?
Hello!
I just got my P10 Lite today and have rooted it but I cannot seem to find the profiles for 720p or 1080p video recording. They are not present in media_profiles.xml so does anyone know where I can find and edit the bitrates since the default bitrate of 16mbit is way too low in my opinion. Thanks in advance!
Bump. I believe the files should be similar on the P10 as well so if anyone has found the file for 1080p video framerates and bitrates then please share it with me/us.
