Best texture formats for ios / android

[kubas121]

What are the best texture formats to use on android and ios?
I create my textures with TexturePacker.

Yes but what texture formats give each platform best performance and the least probability of bugs on specific devices

I use png’s and then pack them into a .pvr.ccz and I don’t seem to have any trouble.

That depends on your goal and needs:

Are you optimizing for:

1. Speed
2. Memory
3. Disk loading
4. Quality
5. Cross platform

Do you need special features like hardware encoding or asset encryption?

As you see, there is no “best texture format”. It really depends on your goals and your needs.

I want to use a texture format that is GPU-decoded and works on iOS and Android. I can’t find documentation about a format that meets those requirements.

ETC1 (or ETC2)? PVR (one of the several formats with the PVR prefix)? T

Is this matrix of Cocos2d-x supported texture formats updated? Is ETC2 supported? PVRTC2/4? PVRv2 and PVRv3 don’t appear on Apple’s developer docs site. I don’t know how they correlate with versions of PVRT.

This page on Apple’s site says Apple favors PVRTC, but “OpenGL ES 3.0 also supports the ETC2 and EAC compressed texture formats; however, PVRTC textures are recommended on iOS devices.”

Another thread on this forum suggests that TexturePacker’s PKM is ETC1 encoding, but PKM is not listed on the Cocos2d-x Texture Formats Supported list (link to the list above):

Texture optimising: PNG vs. PVR.CCZ

With ccz compression you can encrypt your sprites sheets so no-one can easily rip them off. Also make sure you select PVRTC2 or PVRTC4 for image format for the pvr file. You will get x16 or x8 less RAM used compared to PNG 8888. The compressed pvr files will also render faster due to lower memory bandwidth and better texture cache usage. Beware though, TexturePacker doesn’t yet allow you to create mipmaps. You’ll need to use PVRTexTool for that.

Oh, and alpha encoding is important, but I’ll consider a format like ETC1 that doesn’t support it.

Is anyone using a GPU-decoded texture format on iOS and Android?

Update: I’ve used the Configuration class to determine that my Android device supports ETC1 but not PVRC:
