I've noticed when playing video that lines/edges get really jagged and look aliased.
My videos are all native resolution (1024x600) and look fine when played with software decoders (like MX Video Player SW mode) but stutter and/or waste battery when using SW.
I was wondering if anyone has found a way to tweak the hardware decoder so that it produces correct output (not aliased or oversharpened or whatever it's doing here). Any ideas? GL tweak? Maybe some config files in /system or something?
Thanks for any help you can provide. I'm rather shocked at the video quality, and really want to love my KF, but coming from iPad land, I'm very disappointed by the jagginess of sharp edges in video playback (most noticeable on sharp edges/curves/text in videos).

I have been experimenting with video playback on the Tytyn, but am becoming disillusioned with the results!
I use PocketDivX Encoder 0.3.60, to convert using 2 pass xvid and b frames, and TCPMP, and the results were truly stunning on my old Kjam.
Whatever I try with the new Tytyn, does not even come close to the performance I was getting on my old device.
Does any one have any suggestions or recommend a successful encoding method that actually works on the Tytyn. I would like to hear from anyone who has managed to get a playback quality the same as the Kjam/Wizard i.e smooth video without loss of lipsync or jerky framerate.
Thanks
search for TYTN + TCPMP on this forum... this has been discussed A LOT.

Hi there & welcome to our videoplayback problem:
http://forum.xda-developers.com/viewtopic.php?p=354421#354421
It's not all bad, but I can't find any workaround for the meantime. Look out for The CorePlayer (The new TCPMP), hopefully when released, it will address these issues we have discovered. Meantime I am using 'ImToo_DVD 2 Ipod Converter' , which converts to high quality Mp4 format and plays back just fine for now and is definately on par with Divx/Xvid AVI encoding at 768kbps! It also converts a whole film in practically 20 mins plus compared to PocketDivx_Encoder or DVDx.
I have tried the Im too to ipod converter, and have had some very pleasing results.
Could you possibly let me know what settings you have checked/unchecked in TCPMP, for optimum playback of the resulting mp4 files?
Thank you very much, your help and advice is greatly appreciated.
Best regards
Pergolesi
yeah I had a good experience converting to mpeg4 except the filesize was much larger (almost twice the size as divx) is this the norm cause of divx compression?
MPEG4 Videos in TCPMP
Personally, I use the following settings for ImTOO DVD to iPod Converter:
Video Bit rate:512 or 768 (difference is negligable but size is better @ 512kbps)
Audio Bit Rate:64
Sample rate:22050
Channels:2
Video Size:320x240
Profile: iPod MPEG-4 Movie (*.mp4)
Zoom:Full (keep aspect ratio)
Split:Infinite (though it's nice to have a DVD encoded in the chapters it came in - TCPMP will play them in the correct order if saved as 'playlist')
**Do Check the Audio settings (under the Menu bar) as your DVD will probably have options for differnt Audio i.e English.
I know more settings are available, but this is a short-term fix for me (with acceptable results for me) until the new 'CorePlayer' is released.
In TCPMP the settings really don't make much of a difference either, but just make sure you have 'Video' set to 'Rawframebuffer' mode. I have found that all AVI and MP4 playback without major gripes, but the MP4 gets better results whilst benchmarking using 'ATI decoder'. Fat load of good that does you when it comes to playback though (back to rawframebuffer mode).
P.S. for smaller filesizes, just reduce the video bit rate like you would in AVI encoding.

Great info, I'm sure others will find this just as helpful as I have.
Thanks again.

In TCMP what is the best setting, GDI or RAWFRAMEBUFFER?
Im asking this because on my tytn i can use both of them without problems.

I use Rawframeuffer mode, but GDI will do also. Though benchmarking yields better results in Rawframebuffer mode for me.
I'm using TCPMP. I set ATI IMAGEON Decoder on.
When it start, the screen is not viewable.
But I press the action button, when the movie plays it is normal.
When I paused and resume, video play with low frame rate.
I goto Option, Speed, Select 100%, it's normal.
When I play mp4 videos, I see strange artifacts appearing randomly on the screen using WMP or Media panel. They are horizontal and they look like short white dashes. It happens when I watch youtube videos too and it tends to appears more on higher resolution videos.
I really hope someone can shed some light on the issue. Thank you all just for any comments because this is really bugging me and seems to suggest faulty hardware.
Got this test video from somewhere.

No one else encountered this problem?
This device just doesn't handle video very well at all, at least thats my experience. Especially video with higher bitrates. And yes I sometimes see artifacts, mostly "residue" of clips I've played just before like stuck frames at the borders of the video.
I have the edge problems too
But the artifacts/streaks of tiny short lines are appearing randomly in the screen area, not the edges. I am worried about having faulty hardware. I don't know how pda hardware function, but I have several desktop GPUs dying on me before.
Please guys, I really need more insight into this matter because if it is a hardware problem, I will be going down to the service centre soon.
Please just play a mp4 video and report your observations. I know it means nothing but I will be very grateful.
Have you tried running the vids through CorePlayer?
Have you ensured that the files aren't too big (res or framerate)?
Instead of posting vague information like "do you get artifacts" how about some real info about the files you are using.

I specified I get the problems with mp4 files on WMP and Media Xperiance Panel. The files are DVDs encoded with the tool from "[APP][REF]Full HD (800x480) video playback with acceleration" with the recommended settings(which I believe wouldn't be too high). Also, they lag horrendously with CorePlayer so I used WMP or MXP where they played smoothly EXCEPT with white - - - (dashes) appearing consistently but randomly. It occurs on all the videos I encoded this way when played on MXP or WMP.
In case you want some more details, one of the files played have the following details viewed with CorePlayer's Media Properties menu,
Video: AVC aka H.264
Video Size: 640 x 480
Frame Rate: 29.970
File Size: 20370KB
I thought I would not need to post much details because I believed people here would have at least tried playing videos close to the native resolution of X1's screen.
It seems the problem is only with my device and no one else here is having any problem I am having so I will head down to the service centre.

anybody? no one willing to help test?
I find no problems -am on stock UK Vodafone X1i and encode DVD's onto the SD card regularly (watch on train commute)
No problems with original FW and none since updating to RA2 via SEUS
Have just tried your posted "test" mp4 (crysiswarhead?) and definitely no white --- artefacts at all
It plays OK but is a bit laggy (only just noticeable)
The res is 800x480 which may have something to do with it (bit too high) ... I have been using 480x272 which works great and looks awsome (I use a commercial DVDripper -Aimersoft)
Good luck at the service centre!!!
Thanks for the reply. Unfortunate for me though, I always hate service centres. =(
More input please. =(
Same problem here.
Don't think it's a hardware thingy.. it's just not the ideal encoding for this little machine
I'm already happy I can play a normal mp4 / xvid / 'specially' encoded file on it.
Unless it's all over your image I do not think there is any succes in returning the phone.
they'll tell you it's not the 100% right codec format for the phone and will kick you out.
at least.. that's my thinking
Thanks mate for the response. I love this device and can live with this flaw, but I don't like the idea of having a defective hardware on the *inside*.
I can live with the problems I'm already having, scratch keyboard, wobbly slider, black paint dropping off but the fact that my x1 is havinga defective processing chip inside scares me so much.
Heading down to the service centre now...
There are videos that I encoded that play SMOOTHLY but will white flickers popping out all over. The service centre I know have a demo set, I will try playing videos on thatt and compare and hopefully convince those guys.
so, i just synced a movie to my Focus. It took quite a while, because it had to convert the video, which was high quality to begin with. However, no that it's been converted and i'm watching it on my phone it looks terrible. It's like watching youtube and not youtube in HD. My Tilt 2 had better video quality than this.
Has anyone successfully synced a movie to their phone without it being reduced to trash?
Up until now, i've been able to tolerate the small issues, but if this is the bottom line when it comes to video quality, ATT can have the phone back.
That's because the zune software doesn't do as good a job of encoding video as a manual encoder like Handbrake would do..
Try converting with Handbrake (http://www.handbrake.fr)
and entering the following into the "Advanced" section.. on the bottom of the window and hit enter.
ref=5:bframes=0:me=umh:subq=9:mixed-refs=1:8x8dct=0:analyse=all:cabac=0
These are settings that the Zune HD would take and play without the software re-encoding.. so maybe WP7 will be similar in that regard.
thanks! I hope it works!
poor video quality regarding youtube...if you watch youtube with a wifi connection the picture is ok to watch in comparision to watching youtube on 3g...for some reason the phone uses a low quality for playing youtube and other videos over 3g...hopefully someone makes a tweaking program or a work around because my att fuze played gorgeous video over any connection
I used handbrake to convert a couple dvd's and they look great on the device. They were actually video's I dd for my Captivate but they lok great on the Focus as well.
I notice on some avi videos vertical lines that are probably caused by upscaling - they are even more visible when using HDMI (because the screen is bigger). I tried several players. In one they were not visible but instead the picture quality was much worse.
I suppose the cause is scaling algorithm used by Tegra2 and there can't be anything done (other than upscaling the videos to 720p and converting to h264)? Or maybe there is a player that can do software scaling or allows selecting scaling quality?
Hi,
Just wondering if anyone knows of an android video player app that can handle video's shot at higher than normal frame rates? I just got a gopro, but all the video's filmed above 30fps struggle to play back. I usually use 1440p 48fps, as this gives nice smooth playback and the biggest field of view when i'm skiing. i understand that stuff like this is better off being edited on a pc to get any sort of decent results.....but i'd just like to be able to have a little look at the vids straight from the memory card before i get home too.
so far i've tried vlc, which just becomes a garbled mess, the stock video app which detects it as a sound only file, and mx player which plays back the video in slow motion and plays back the sound in sections (i.e. it will play sound at correct speed, but keep stopping while it waits for the video to sync up). so mx is the best so far, but is there an payer that can actually understand the higher frame rate and play it back at that rate too?
Try the latest vlc nightly. Go into settings and try it with and without hardware acceleration

Have you tried Dice Player?
https://play.google.com/store/apps/details?id=com.inisoft.mediaplayer.a&hl=sv
thanks for the suggestions guys. unfortunately i still have no luck with these players, no matter what settings i used. think i'll have to get used to doing lots of editing first ha ha.
