TextureCompression: Error+Crash when transcoding KTX_TFF_PVRCT1_4_RGBA

[jeroenbakker-atmind]

When running texture_compression_basisu transcoding to KTX_TFF_PVRCT1_4_RGBA will print an error that the input images cannot be transcoded to this format. This results in not allocated resources. validation errors and eventually crashes.

Code trows an error when KTX doesn't succeed. Would be better not allowing images that will fail to not select this format. (Print error or remove failing options). Most likely the input images are not a power of 2 that is a requirement for PVRCT1. As none of the input images are a power of 2, we might just want to remove PVRCT1

Detected on: Apple M2+SDK 1.3.296

Discussed during the meeting, and the solution is to resize the input files to a better resolution (512x512)

[jeroenbakker-atmind]

The files are located in assets/textures/basisu

• kodim03_ETC1S.ktx2
• kodim03_UASTC.ktx2
• kodim05_ETC1S.ktx2
• kodim05_UASTC.ktx2
• kodim20_ETC1S.ktx2
• kodim20_UASTC.ktx2
• kodim23_ETC1S.ktx2
• kodim23_UASTC.ktx2

The original files are located at third_party/ktx/external/basisu/test_files

Commands done to generate the textures.

After resizing it seems like the VK_IMG_format_pvrtc extension is required.
