I'm currently trying to run some benchmarks about whether or not it's beneficial to do texture compression on the device itself. In order to do so, I'm trying to view the textures uploaded to the GPU via the Adreno Profiler. I'm using:
1. Nexus 7v2, which should be running the newest version of Android on an Adreno 320
2. 64-bit Ubuntu Linux sporting an NVIDIA Quadro K600.
All of the textures that I'm trying to use are 8-bit alpha masks. Grabbing a single frame works fine, and produces an API trace. The graphs seem reasonable as well. However, when I try to look at the textures in the Scrubber GL Texture Browser, they do not show up. There's an error in the console from the profiler:
TextureConverter error: ImgInfo unsupported pInput->nFormat
I'm uploading my textures using a combination of glTexImage2D with a null pointer to pixel data followed by a glTexSubImage2D to supply the data.
Any ideas?
It could very well be a bug, because I doubt we have much test content using 8-bit textures. We'll look into it. If possible, it would make it easier for us to duplicate if you could send me the apk ([email protected]).
