I tried to configure compression method to use LZMA in make menuconfig to compile a custom kernel. When I compile it I get errors regarding to compile zImage which is probably due to missing drivers for LZMA compression. I'm using Fedora 20 64 bit and have java jdk 7. How do I add patches into my kernel source to have LZMA compression?

View 1 Replies View RelatedFirst i want to say im running the Redemptive rEVOlution rom and i dont know if this will work on roms with the incredible framework, i think it might.I installed a zip from Calkulin over on the xda evo forum for a compression fix for mms. If the pic is not over the size limit, it wont be compressed anymore. I have just sent about ten pics in a row ranging from 550kb up to 1.1mb and they all went through without compressing! I take no credit for the mod. All credit goes to calkulin over at xda.I found it very annoying that every pic would get compressed. Glad to find a fix for that. BIG. THANKS TO CALKULIN FOR THIS.Now when it does compress a message thats over the size limit, its still" over" compressing it. My limit is 1.2m and if the file is 1.3, it compress' to 44kb...What the hell? Just have to find out how to fix the over compression issue and im happier then a pig in shit.

View 1 Replies View RelatedDoes anyone know how to reduce the photo compression the evo applies when sending a picturemail/mms?I use it rarely, but I had to send a photo someone and my evo auto-compressed it to like 18kb - which is a bit excessive since it destroyed the relevant details in the photo. I ended up just emailing the thing but was wondering if there was something I missed here.

View 17 Replies View RelatedAfter doing a search around, found nothing on this issue. Love my phone! Its great. The problem I have is possibly a little ahead of its time, but here goes.The resolution of the OLED screen is so good, that whereas historically on smartphones, the automatic image 'de-resolution' by my GSM 3G carrier (in this case T-Mobile) in their efforts to speed up the downloads would not be so noticeable on the phone screen, I can't help but see the opposite is true now.For example, on the BBC News website, as you zoom in to look at an image, you cannot see the detail as T-Mobile is compressing the image too far. But I know the Nexus 1 can handle much better that what is being sent through.The question is simply, is there a work around (historically, through dongles and through a PC, no problem) to allow me to either selectively get the full resolution image, or alternatively, is there a browser that allows me to select images individually for full download so I get the full detail that I want?
View 8 Replies View Relatedwhere I have got right now on my phone, which is:
1. I updated to stock 2.1 using the sprint update tool.
2. I followed the video tutorial to root the phone
3. then i used joey's page (http://www.joeyconway.com/sdx/custom/index.php) to install the his kernel (joeykrim-SDX-kernel v2.0.4 (includes root)).
I have done nothing else to the phone but this and removing a couple of bloatware apps (i checked the list of permitted deletions before i removed anything.) I have not installed a new recovery..at least i dont think that I did as part of one of the other operations I performed (as an aside, i am not really sure what the custom recovery is or what it is used for, so i didnt install it...i guess i need to read up more...)
So that is where I am..but i have a couple of questions.
1) i am now having issues with my wifi connection - the signal reception is very spotty in areas where i should have atleast 2 bars of reception, and the wifi often cuts out completely....Is there any know corellation between joey's kernel and this wifi issue? I have searched the forums and have found nothing that answers this.
2) Is there an easy way to get back to the stock kernel? I have read that i can get back to stock everything by using the sprint download center where I did my original 2.1 update. But is there a way to get back to just the stock kernel without wiping the phone?
Apparently you can't have a file in "assets" larger than 1MB (except for certain file types) because it's considered too large to uncompress. But I'm finding mixed info about how to circumvent this limitation. Some say that you can put the files in "raw" and avoid the limitation but others say that files in "raw" are compressed too.And there's the -0 aapt option that can be used to turn off compression for certain file types, but there's no way to specify aapt options in Carbide. I realize that I can break the file into pieces, but that's error- prone on both ends.And using one of the known uncompressed file types not only confuses things but also runs the risk that the Android PTB will decide to start compressing that file type.
View 6 Replies View RelatedI want to download an image from the 'net and set it as the users background. This works great over wi-fi, and some 3G networks, but others (T-Mobile UK, for sure) seem to compress the images before sending them. This effect is noticeable when using the browser, too - however, if you long press on an image and save it, when viewing in the gallery it is either not compressed at all, or substantially less so. I want to be able to do this in my own app.I assume it has something to do with the HTTP headers, but of the ones I've modified, none has made a difference.
View 2 Replies View RelatedI've had the Nexus one for a couple of weeks now, last night I thought I'd have a closer look at some of the snaps I'd taken, check the quality like. I was MT pinch zooming into them and to be frank I was less than impressed with both the detail and the compression. To double check I quickly popped outside and snapped a piccy of a rather charming sunset we were having, ensuring I was on 5MP and super-fine.
Took a look in the Gallery app and same thing, looks about 2MP with some heavy duty compression when you zoom in.A little baffled by this I thought I'd check them out on my desktop monitor so emailed the same photo to myself. Much reduced Compression artifacts! The gallery images that you view are clearly some low quality version of the pic, natively I don't believe you can truly appreciate your pics on your handset.
Anyone know how to change how much messages compresses an image when u try to send it in a text? When I take a picture and share it in messages it says picture is too large and starts compressing it.

View 3 Replies View RelatedI am trying to save a bitmap in a JPEG format, and i can see that the image is always stored with a lower quality even if i give the compression level as 100, however for PNG it is working fine. Similarly during Media.insert() or getContentResolver().insert() the image is stored with a lesser quality, I can see in that the compression level is 50 in the Media.java, however I tried to create my own method for the same function with quality 100.
View 3 Replies View RelatedSo from what I can tell Media.insert Image is locked to heavy compression on all images. This includes when passing in the path to a photo in the filesystem. As a test I used a 3000x2000 pixel jpg which had been previously saved at maximum quality and was ~6MB. After passing the path to Media.insert Image, the resultant copy (still 3000x2000) is 623KB. I passed in another copy of the 3000x2000 image, this one compressed down to 393KB. After Media.insert Image, the image filesize is 492KB. I'm wondering if there's a way to specify the compression when images are saved by insert Image. I'm also wondering why this is recompressing jpgs, rather than simply copying them into DCIM. A side-effect of opening and re-compressing these images is that it imposes a rather low VM cap on what insert Image can handle. I'm getting out-of-memory errors when trying to pass the path of a 10 megapixel image.
View 5 Replies View RelatedI've tried a bunch of my own images as my lock screen, all set at what I've been told is the correct resolution, but they always come out looking pixelated, dull and blurry.The images look extremely crisp and bright when i preview them in the lock-screen selection area - but when saved, there's a huge difference in quality.The resolution which fits perfectly is 320x455, but pretty much everyone online says its 320x480 which I know to be wrong because you can see it clearly doesn't fit the screen when you're selecting it - and so it gets resized up.I've tried JPG, PNG, TIF.I've tried different sample rates, different color pallettes - nothing works.Even using the default HTC one (which looked gorgeous originally) - whenever I apply it now, it looks like it went through some 60% JPG compression.artifacts all over the place.
View 9 Replies View RelatedI've started to notice that past a certain point, my phone doesn't clip like I'd expect it to, but sorta softly eases into a really terrible sort of compression that drives me nuts, particularly when I'm trying to run sound through my car stereo over A2DP. It seems that once you reach the last 3 or 4 ticks of the volume control, the music will start compressing heavily which really mucks with the audio quality and causes the music to lose punch in the midrange (as generally it seems tracks with high levels of bass are affected by this.) Has anyone else noticed this? I assumed at first it was an A2DP issue (possibly conditioning the sound for the A2DP stream?) but then heard it when hooked up hardwired as well.If you have noticed this, is it just a 'feature' of the phone, or are other music player apps not affected by the issue? Is there one you'd recommend? Obviously I'm not expecting audiophile quality sound but it is quite annoying when suddenly the middle drops out of a track in the midst of listening.
