Hey guys, I got the quake3 running on my xperia, but its not really playable so Id like to try quake2. However I cant seem to get it running!
Downloaded it from http://quake.pocketmatrix.com/ . When I start up the app I get like a control interface with a couple of buttons "Attack", "A", "B" etc. But behind these there's only a gray background. Sometimes the game seems to start, as I can hear in-game sound. But the screen stays the same. Also tried the xscale optimized one but that didnt seem to work either.
Help plz
This is one of the first things ill be trying when I get mine, Ill keep you updated. Hopefully it will be sometime next week when phones4u stock it
That'd be nice. Hopefully you'll get it as soon as possible
Hmmmmm.
Just tried Quake. I start it with the X1 closed and it comes up but the display is part white i just get the weapon selection bit and the A B buttons etc, I try opening the X1 up and closing it but the display just switches orentation. when i pess the x to close it asks me if i really want to quite, when i press yes, the main display flashes up with 'Single Player' 'Options' etc!
Any ideas anyone?
Installed Quake2. I run the program it comes up with a box saying by Dan East or something, press ok then nothing happenes
weell I get a bit further than that but still doesnt work for me neither. Anyone with more luck?
I find it puzzling that in general Windows on PC "just works" but Windows Mobile breaks compatibility with even slight changes to the OS and/or hardware.
Why should a higher resolution screen break an app? Does Windows Mobile have no support for dealing with that? Surely you would expect it to detect an app trying to use a lower resolution and put it in some sort of wrapper to pad the extra space.
Its bizarre that even Java apps have compatibility issues from phone to phone. Why no standards so they work on ALL headsets? The whole mobile market is a shambles when it comes to compatibility but Java seems to have a better success rate (well, it usually displays SOMETHING) than Windows Mobile does, despite their being more variations of it around.
actually I dont think its the resolution...
Also, wvga has a different aspect ratio. So it makes sence that some apps dont fill the whole screen
Hi All,
i found solution for unlimited recording on android device, it has pros and cons so hopefully some programmer will come and modify the buildin camera apk.
here are solutions they are working perfects but the problem is the quality is no where close to the buildin cam apk.
1. lgCamera
2. Snap Camera HDR
3. moto x camera apk its free and in my opinion its quality better than the other 2.
so the problem of limited recording is not due to format fat32, because htc on buildin cam apk record 30 minutes and stops and its size is 4gb, but i have tried lgcamera was recording over an hours and its size was 5.7gb.
i do not keep it long, i hope some programmer modify htc one cam apk to record unlimit or auto splitted to 30 minutes duration, also modify its zoom default to the value of 50% because htc one cam is way zoomed out.
so if any genius person modify the camera apk then it will be best solution, it just need to override the default camera apk setting when some one modifying its camera apk.
some time when we have party i do not like to go and modify zoom setting and start record again every half an hour.
Thanks for any programmer who modify this and good luck with the rest for temporary solution.
Hi,
snap camera records 30fps with 20mbit in low light, but the result is darker then htc stock camera.

I could be off here, but since you said recording stops at 30 minutes, I think I have a solution:
In /system/etc/media_profiles.xml, there is a "duration=" setting for each encoder profile. This can be set to either 30 or 60, and currently all profiles except qvga are set to 30. You may be able to set this to 60 and be able to record up to 60 minutes. Report back.

You do realise that routinely changing the zoom is a terrible idea on the One?
It's a digital zoom, not an optical one, so all you are doing by zooming in is losing pixels - this is fine if you are shooting something and wish to zoom in for effect, but as a general rule if you want to get the best quality out of the camera, you should leave zoom well alone. This is especially true of the One as it doesn't have that many pixels to play with in the first place.

hello homeslice976
Thank you very much for the information you have provided. i have uploaded 2 screen shots of the xml file you have stated and also uploaded 2 xml file which are original xml file on my htc device, but i think the device must be rooted to replace those xml files? am i wrong?
if i need to root my device then i will try to do it later today as my connection is very slow right now.

Thank you Dave,
i will test to video one with zoomin at let say 40% and other will let zoom alone but i will crop the video to equivalent of 40% zoomin video, i will compare the 2 side by side and will report back the result.

yes you'll need to be rooted. you don't need to do anything with media_codecs.xml. Just media_profiles.xml.

zoomin htc one
hello Dave,
i have tested the video, i captured 2 video phone was at stable position, one without touching zoom and the other shoot was zoomed about 60%
then i cropped the one with 0 zoom to the same frame as the one with 60% zoom.
the result is as follows:
after cropping the video file from 1920 x 1080 became 775 x 425 well if i keep this size the file remain same quality but when i cropped back to
1920 x 1080 the quality is blury and no where near the original or the video was shooted with 60% zoomin.
so i believe the zoomin in htc one does not effect its quality as long as you are not zoomed extreme.
when you crop video and resized you will lose quality the same as zoomin, but all camcorders allow certain zoom without affecting quality, so i believe htc one zoomin is the same, but some video camera have advanced zoomin to go beyond limited for instance 72x advanced zoomin and the normal zoomin is 20x, so if you go beyond 20 you still zoomin further but you will lose quality and shaky footage.so the safe is to stay with 20x range.
all edited with after effects and even i did not export the out put, but after editing them compared them side by side, it is like day and night the quality differences between the 2 videos.
thank you though for information, i will try first to root my device and see if i can go beyond the limited recording.

hello again
i have changed those number to 60
i started from
<!ATTLIST EncoderProfile duration (60|60) #REQUIRED>
and each
<EncoderProfile quality="cif" fileFormat="mp4" duration="60">
so as you see all are in 60 minutes but no luck sofar i tried twice
1st record 25:39
2nd attempt records 26:04
both size are 3.79 gb in size
now i started recording again to see what is the the outcome if it is the same then i have to try to changed back to 30 at least its 30minutes, so i think it is the size limit thing
update: it is size limit issue, i checked again it says video size limit is reached.
i think it is be useful if some one try to write a code to state when ever the video reach limited time then start again automatically.
but thanks for the advice, i will let you know if i come with better solution..
thank you.

zindu

Sorry - that was just a theory anyway. I'll keep looking around for something else that might be limiting the file size.

Hi guys, this seems to be the only real discussion on this issue going on at all.
Has anyone been able to find a way around this limitation?
the problem is there are many know how to solved but they do not shared with us.
only who does not know and they spread a word over the net and same crap like, it is due to format type, let me tell you i have solved mine on htc one no problem what so ever until i stopped manually.
i am not a programmer but currently when i have time i try to learn java then i will after that develop simple app and progressing from there and will help the community but that take up to 1 to 2 years.
any way how i solved mine? i do not know my self but i did 2 things will shared with all of you.
1. i rooted my htc one device, there is plenty guide on this forum.
2. i decompile my camera apk and i change a picture and i can not remember if i mess little with codes or not but i doubt i did, so i deleted the original camera apk and replaced with my modification.
i will be glad to share my camera apk with you if you think it might be due to this modifications, i tell you what? i never update the system software now, because i am afraid i will lose the unlimited recording, so it works for me but i do not know how, but in future when i understand java programming i will help every one in this community.

Zindu, thank you so much for sharing.
I emailed Google about this here is the response I got:
"Thank you for contacting Google. I appreciate your patience with me as I look into this issue. It seems as though the limit placed on the video data file of 2gb is written into the android operating system. This is in effect on all types of android devices.
I have researched a few video control apps, they follow the same rule and stop at 1.9-2gb. At this time I do not believe there is a work around for this issue. I do not have software update information available either. Some of the research I have done points to a possible legislative law that limits the video recording time of mobile devices as it takes away from video recorders."
pal first thing you do undock the cam apk from the bar dock on your phone, see if it is working, what i mean by the dock is the bar on your phone on the bottom which have space for 4 or 5 applications, so undock cam apk from this dock and used on the main windows view.
if that does not work root ur phone and undock cam apk from dock bar.
if both does not work then if you have htc one i will upload my cam apk so you can install it on urs.
mine was limited to 4gb now its unlimited in size and durations, a programmer can develop application to over ride the camera system settings, so if i learn java in future my first apk will be try to over ride system setting.

I have a Nexus 5. My camera app is not docked. What should I do next?
if its not docked then rooted anyway see if it works?
what i did i undocked, rooted, modified a pick and some codes in xml file, and it works for me so i do not know which step caused the fix, but you need to root your device if you want to replace system application on your phone.
try to root your device first and try to modify xml file see if it works, if it was htc one i could help because i can upload xml and apk file.
that is all i know for now hope someone who have better knowledges to help you out but i hope i learn java within a year or too then i be able to fix this issue.

Ikr, it is pretty ridiculous. Zindu is right though, it's simple enough but the people who can figure it out don't care. Most people just don't seem to need their phone for our purpose.
My workaround has been SVR Pro:
-Upsides -It will record in fragments until your storage is full.
-You can use your device while recording
-You can record with the screen turned off !! which is epic for battery life!
-Downside -you loose like a second of video between the fragments

So I've discovered that a simple terminal command fixes the black bars on the left and right when outputting through HDMI. It's caused by the tablet outputting a 1280x800 display to a 1280x720 signal. This is easily fixed by changing the device's resolution with the following command:
wm size 720x1280
To revert to the tablet's original resolution, use:
wm size reset
You may need to run the "su" command first for these commands to work, and you do need to be rooted in order for it to work. This will cause some things to get wonky, like the nav buttons disappearing in landscape orientation or the status bar being hard to pull down (perhaps solvable with a change to the DPI), but if you're planning to use this trick for gaming (which was my reason), using something like Smart Launcher 2 with a controller makes this a non-issue. If you want a quick and easy way to switch back and forth, try QuickTerminal on the Play Store and set up both terminal commands as "Quick Commands", or at least that's how I've done it. Now, the picture on your TV will fill the screen. This is as close to Console Mode as we'll probably ever see on this device, so I thought this might help a few people out!

I've been doing something similar with the NOM Resolution Changer app but I can't get the DPI settings right to match the 720x1280 res. It gets a bit tricky getting back into settings etc after changing the res as my app drawer is inaccessible after doing so. I always just resort back to default with the fail safe timer, I really don't want to get stuck in a resolution which i can't get back out of.

I haven't had that probably making the change manually, and I do believe I tried the app you mention and had the same issue, so you might wanna try testing the terminal command out; if it messes up, you can always reboot the tablet and everything will properly reformat for the lower resolution and then you should be able to change it back with "wm size reset".

Thanks rchrdcrg, yeah I'll give it a whirl that way. It is really annoying having those black end sections on the output!!
I've got a chromecast and been trying to get the 'cast screen' option to work using r3pwn's method here http://forum.xda-developers.com/hardware-hacking/chromecast/experimental-enable-mirroring-device-t2812193/page167#post55119152
I thought that might be worth a shot to see if the output res remains at 1200 x 800 for the mirror but I can't get a picture to display, only sound, when it connects and tries to cast screen. I'm thinking it probably won't make a difference though as I have just bought a miracast ezcast m2 dongle too and that still displays at the 1200 x 800 resolution when miracast is used. It probably is just a rom limitation at the moment.

Yeah, I "borrowed" a Chromecast from Best Buy and could never get screen casting to work. You might want to see if changing the resolution fixes this issue with Miracast as well... I have a suspicion it will, and that might be useful to some folks. I sure wish I knew how to force the HDMI output to 1080p; it switches over when playing a 1080p video, so I know it's possible, but I don't know enough about development stuff to know how it's doing that, and forcing the resolution to 1080x1920 with the "wm size" command just displays a 1080p picture downscaled to 720p.
try vlc beta off the play store
here's a sort of rant and with a video playback only solution. Not sure how to hide the rant part. I don't forum anything much.
I bought a Belkin miracast adapter off amazon, and have had trouble getting videos playing properly in full screen. It would mirror the 1280x800 with videos played with regular video apps ( MX player, Archos player, stock) which would be 16:10, and would have those bars on either side on both my 1080p insignia tv and our pseudo 720p panasonic (actual res was 1024x768, but at 16:9, which should be illegal to market as a hdtv). I know from previous experience with my galaxy s4, which the samsung video app would mirror only the video at the correct tv resolution, leaving the phone as the remote. You could also use other apps while any video was playing through the samsung watchon (video) app. So randomly downloaded the vlc beta off the play store. It works for the tegra note 7 the same way samsung set up theirs, minus the multitasking(so far). It took me weeks on and off being frustrated with apps that wouldn't recognise that mirroring was enabled to take advantage of the external display. It's kinda whatever now seeing how much time I spent trying to get the video to play properly by itself, for my s4 I tried mhl cables, chromecast, dlna. this works a lot better
So if you just want videos to play, use the vlc player beta. you can use miracast or hdmi. works the same with both. Only if I could miracast surround sound. that would be nice.
I've just started using my tablet and a HDMI cable to run XBMC. This tip has saved me much frustration.
I already use Tasker which can send terminal commands as an action to make it easier. Tasker does have a HDMI plugged state which should allow this to be automated but for some reason tasker doesn't seem to detect it, not sure why yet.
So I've been fiddling a bit more to optimiser the HDMI experience. I've discovered an app called second screen that let's you sert display profiles and launch then the HDMI is plugged in. Thee app sets the size, resolution, dims the screen and force closes the UI to make sure the new settings actually come into effect. It will also revert the changes when the cable is removed. Does need to run on a rooted device but mine is already.
Seems like nexus player supports only RGB limited. Since my HDMI port (which is shared by other sources) is configured for full RGB this results in poor blacks when I switch to nexus player. Anybody knows if it can be switched by to full RGB or even better to YCbCr? Since its a dedicated player I am thinking this should be a must. Even chromecast behaves better in that department.
Are you me? I've had the same issue, and asked on the Nexus help forum about it. "Paul from Google" says that there's no way to get RGB Full.
I'm pretty sure it could be done with a custom kernel though.
http://referencehometheater.com/2014/commentary/rgb-full-vs-limited/ - here is some explanation. I have my TV set on Auto and have never noticed any problems. Will have to check if it is able to display <16 black and white above 235 - by the way limited RGB is almost as stupid as overscan in TVs. What were they thinking limiting the colors like that?
Exactly !!! If a company expects to win the home theater section of any house and gain respect with the videophiles these details are elementary. Even if for whatever reason they decide to keep this behavior as a default, just add a video section in settings where the user can configure the way he/she wants.
Did a test with a black clipping pattern and the Chromecast is able to show 1-16 but the Nexus Player does not unfortunately.
If a TV's brightness is calibrated so that 16 is reference black though, does it matter I wonder that the Nexus Player can't show 1-16 with the assumption that Shows and Movies from the Google Play store are all 16-235 anyways (is that a correct assumption)?
looking over the kernel code it seems that the hardware will support these color ranges, lots of code to dig through, right now im looking through:
https://github.com/ion-storm/nexusplayer/tree/dev/drivers/external_drivers/intel_media which contains the hdmi video drivers, right now I cant seem to find where I can enable the option, lots of code to look though.
I believe that google support guy meant that there is no ui toggle to switch between these ranges, but what we can do is force detection/color ranges within the kernel if the hardware supports it, this is new code here so if anyone can find any references on enabling this, I'll be happy to look it over.
Can somebody please tell me whether it is possible to use the yotaphone 2's EPD as a (small) display to do some basic word processing outdoor out in the sun? I.e. to attach a keyboard/mouse to it (e.g. via bluetooth), to open some simple word processing app or even sthg like google docs, and then to just start working.
I have actually been looking for quite some time for some way to do this and I can't for the life of me understand why there aren't better solutions out there. I am always pleasantly surprised when I type notes on my Kindle Paperwhite. Of course it's a lot slower than on an LCD, but I am not a fast typer anyway, and I could live with some lag - if that's the price I'd have to pay to finally be able to work outside. I have thought of the Raspberry Pi x Kindle solution (but you can only type on sthg like vim); of ebook readers with an open OS that you can attach a keaboard/mouse to (like Onyx Boox that runs on Android 4.0 - and I'm still thinking about that); or of an e ink monitor (too expensive). But it is time for me to change phones, and if this works, I might actually consider it.
If anybody has any experiences or thoughts or - better yet - videos to share on this, I'd be very grateful... Thanks!

I haven't tried this personally, but I am fairly certain that this would work. Android supports bluetooth keyboards. The only limitation would be that you have to use mirrored mode, because there are no proper word processing apps made native for the EPD. Plus the system might not enable external keyboard for EPD apps only. Not sure on the latter though, I don't have any bluetooth keyboard/mouse to test this with.

Thanks Jeopardy. Can you (or anybody else) tell me whether there is an active developer community working on those EPD apps? And also - if you have to use mirrored mode, does this mean you have to open the phone and the AMOLED screen has to be 'on'? On can all of this just stay in the 'background'? And does mirroring to an additional lag beyond the usual - and much slower - e-ink refresh rate? If anybody has any first-hand experience with this, I'd really be curious... Thanks!

Well there are some developers, myself included, working on EPD applications. But not a lot. There should be more once Yota releases the device in USA around mid-August.
Mirrored mode does not need the color screen to be turned on. Of course behind the scenes it will wake up the system to similar state as if the AMOLED screen was on, but that's handled automatically. This means more battery use, but you should get a lot more out of it than using the color screen, especially on static apps like word processors which don't update often.
You can handle everything from the EPD. You can, for example, create a shortcut on the EPD for a word processing app, which will automatically enable mirroring and open that application. The lag on EPD when mirroring should be about the same as on native EPD applications, but of course you will notice it more because you can easily compare it to the non-laggy color side. There's only a few extra algorithms for turning the color image to nice greyscale, and some logic for creating additional "flashes" to fix ghosting when switching between apps etc. Should be fine for word processing, especially on external keyboard, provided you can write without constantly checking which letter you just pressed. The refresh rate on the EPD is about 8 frames per second, or one frame every 0.12s.
If you're seious about outdoor word processing may I suggest a rooted Nook Simple touch? It is small and light and a fraction of the price of a Yotaphone... as well as having a much bigger screen! You can pick these up for around 40GBP in good/new condition and although it will be a fair bit of messing around with rooting you are unlikely to come totally unstuck, and there is a lot of support on XDA to get you help if you do. With the NST device, you use the OTG USB mode to attach a bluetooth dongle, hard wired full sized keyboard or whatever to your desire. Pop over to the NST forum and there are many threads on this topic, but to whet your appetite here's someone who is doing that with a solar panel to power the setup!
