Title: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kiffa on April 17, 2013, 05:48:44 am: I used Texture.setTextureCompression(true) ;

But i'm not clear how it works, create normal-texture from image file -> compress it to ect1-texture -> upload to gpu, right?

Could i use pre-compressed etc1-texture file which is created by the etc1 tool of android(or another etc1 tools)? My purpose is to decrease the size of APK and the memory usage (in order to use larger texture to improve the details).

Does texture compression always improve the performance? I know it will decrease the bandwidth usage of texture, but i am not clear if it will consume more time to access the texels(seek/uncompress/read etc...);

Post by: EgonOlsen on April 18, 2013, 08:26:31 am: Yes, that's basically how it works. And no, you can't use precompressed textures. There was some technical issue with that, that i don't remember ATM. Compressing a texture to ETC1 will give you the same memory savings as using 16bit textures, but the image quality is usually higher (as long as no alpha channel is being used).
Using ETC1 increases texture upload times but shouldn't have a negative impact on performance at runtime. It might improve rendering performance, but to be honest, i've never experienced that.
In Config, there's this switch: http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#cacheCompressedTextures (http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Config.html#cacheCompressedTextures). If you set it to true, give your Activity the rights to write files and assign a Virtualizer to the TextureManager, jPCT-AE will cache compressed textures on your SD card to decrease startup time for subsequent runs.

Post by: kiffa on April 18, 2013, 10:28:14 am: Thanks, and do you have the plan to support precompressed etc1 and etc2（which is the one of the standard of es 3.0) in the near future? I think this feature is useful for mobile app.

Post by: kkl on January 15, 2014, 01:46:09 pm: It would be great if etc1 can be cached in memory and be used during runtime. I had tried it on live wallpaper and I notice it's extremely slow (a short stutter) when live wallpaper resumed from sleep. Converting etc1 during runtime after context change makes the live wallpaper looking quite bad. Is there any plan for this feature in the future? Would appreciate it a lot for live wallpaper case.

p/s: Using cacheCompressedTextures still looks slow during live wallpaper resume.

Post by: EgonOlsen on January 15, 2014, 02:16:10 pm: Keep in mind that this Config switch does nothing unless you assign a Virtualizer to your TextureManager.
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 15, 2014, 03:23:48 pm: Yes, I did set the virtualizer to TextureManager. It's noticeably faster than not setting the cacheCompressTextures, but it still stutters when resuming the wallpaper.

Post by: EgonOlsen on January 15, 2014, 08:44:59 pm: Might be the driver then...i don't see how to improve this. Loading the data from the sdcard is fast, that can't cause the stutter. And the rest is just simple texture uploading as usual. Is it different in performance when not using texture compression?
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 16, 2014, 03:22:44 pm: Yes. Without compression, the resume is almost instant, but stutter a short while with compression. Probably I'm compressing few big textures, and it's slow to open file IO for multiple files. Is it possible to keep etc1 raw data in memory (if we use the compression)? I think the live wallpaper would resume instantly that way.
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: EgonOlsen on January 16, 2014, 08:31:57 pm: I could add some option to cache into main memory instead, but i'm finding it hard to believe that loading from the sdcard should be an issue. Just to make sure that we are talking about the same thing here: We are talking about http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Texture.html#setTextureCompression(boolean) (http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Texture.html#setTextureCompression(boolean)) here, not about http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Texture.html#compress() (http://www.jpct.net/jpct-ae/doc/com/threed/jpct/Texture.html#compress()), right?

Can you post some logs that help to see where the time is spent?
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 17, 2014, 02:47:50 am: Yes, we are talking about setTextureCompression(boolean). Just a little thought; if etc1 data is kept in main memory, should the original bitmap data be cleared from memory? Or else, it would have two copies of same texture data in main memory which would likely to cause out of memory problem, IMHO.

BTW, here's the log when live wallpaper resumed.

Seems like it loads a lot of compressed textures but I set compression on for only 7 textures. I'm using the Hello World project from JPCT.

Post by: EgonOlsen on January 17, 2014, 12:03:29 pm: The additional textures that it loads are the mip maps. If you are using some textures for blitting only, you can disable mip mapping for them to save the time and memory.

I'll have a look at the loading code later...

However, even with an in-memory cache of the etc version, i still need the raw texture data. Why are you compressing the textures anyway? Just because you can or because it won't work otherwise?

Post by: kkl on January 17, 2014, 12:19:17 pm: in some devices, it returns 1285 glerror... Making textures smaller fixes that error.. I assume it's gl out of memory issue. But smaller texture makes the app looks bad..

if keeping etc1 cache and raw texture data at the same time, we might run into out of memory issue for main memory. Just out of curiosity, why do we still need the raw texture data when we have etc1 cache?

Post by: EgonOlsen on January 17, 2014, 12:25:46 pm: ...to calculate a checksum for the cached file. This has to be done to keep the files between different runs of the app. For an in-memory cache, this wouldn't be needed, but it would require to add an alternative branch to the texture pipeline, which i'm trying to avoid.
I don't think that the 1285 error has anything to do with memory. It'a more likely that is has to do with mip map creation. Try to disable etc1 and set Config.internalMipmapCreation to true and see if that fixes the problem with the 1285 error.
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 17, 2014, 03:03:02 pm: If we have in-memory cache, not only we can save more in main memory, but save memory in gpu too. I think it's a win-win solution with abit more effort to do it. I had many crash reports with my app due to out of memory issue. However, compressing it makes it look bad on resume (due to the stutter). It would be nice if we have both compressed data to reduce chances of memory issue to match industry standard as close as possible. What do you think?

I can't replicate back the 1285 error anymore. It happens pretty randomly, I think. I'll try use Config.internalMipmapCreation if I get back that error. Thanks alot on the solution.

Post by: EgonOlsen on January 17, 2014, 03:05:12 pm: I don't see why an in-memory cache will save memory on the GPU...?
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 17, 2014, 03:19:44 pm: Correct me if I'm wrong. The GPU driver reads etc1 data directly as texture, isn't it? Hence, gpu stores only etc1 compressed data in its memory instead of uncompressing etc1 first and read the texture.

Post by: EgonOlsen on January 17, 2014, 10:07:48 pm: Yes, it reduces memory usage on the GPU but keeping an extra copy in memory increases main memory usage. However, i had a look at your log output and my code and the loading itself is dead cheap (1-2ms). What takes much more time is the copying from the actual texture data into the buffer that is used to create the texture in case that it can't be found in the cache. This code also calculates the checksum, which is why i can't omit it...i'll try to come up with something better...

Post by: EgonOlsen on January 17, 2014, 11:08:40 pm: Could you give this jar a try: http://jpct.de/download/beta/jpct_ae.jar (http://jpct.de/download/beta/jpct_ae.jar)? It doesn't include any kind of memory caching, but resume times should be better anyway. I would be interested in the log output of this one...

Post by: kkl on January 18, 2014, 03:20:06 am: 1-2ms? That's extremely fast, judging from file IO process. How many and how big are the textures in your case?

BTW, here's the log after using new jpct :

Seems alot faster than previous, but the stutter still noticeable, just that it's shorter time. IMHO, if user chooses for sdcard caching, then we keep the raw texture data for checksum and backup. If user chooses for in-memory caching, then the raw texture data can be removed permanently. How about that? btw, is there any way to check the time taken for the gpu driver to process etc1?

Post by: EgonOlsen on January 18, 2014, 03:32:58 pm: The time used to process the actual data is the second number in the "...done in (...)" outputs. The first one is the buffer processing. That number went down from 1.4 sec to 0.5 sec in total with the latest change. As you may have noticed, i somehow don't like the idea of this memory caching. I think that optimizing the current process is the better idea and i have one idea left that might help to get rid of this buffer processing in most cases. I'll report back when i tried that...

Post by: kkl on January 18, 2014, 04:17:10 pm: Yea sure, would love to hear from you soon.

I do notice you are not fond of in-memory caching, but I hope I can convince you too. I read an article about etc1 compression, and it saves a whole lot bunch of memory http://software.intel.com/en-us/articles/android-texture-compression (http://software.intel.com/en-us/articles/android-texture-compression). It tempted me so much till I can't resist thinking of using it. If JPCT is open-sourced, I'd love to help on this part ; )

Post by: EgonOlsen on January 18, 2014, 09:02:59 pm: It's just that caching the etc1 data in memory seems like the wrong solution to me...i can't tell exactly why. Anyway, try this jar: http://jpct.de/download/beta/jpct_ae.jar (http://jpct.de/download/beta/jpct_ae.jar)
Title: Re: Could i use pre-compressed ETC1 texture file in jPCT-AE?
Post by: kkl on January 19, 2014, 03:31:41 pm: Yes, it's alot faster now. I can barely see the stutter, even though there is still a very short stutter. Hopefully that short one is the driver trying to process the etc1. Thanks alot for your help on improving the caching. Anyway, I still look forward to in-memory caching in the future if you change your mind ; )
