Basis Failed to transcode image (Safari 17.0, iOS 17.0) #5509
Comments
Hi @cd-vaughamhong , I've run a few different projects which use basis and they all work fine for me (for example https://playcanv.as/p/SA7hVBLt/). This is on ventura (13.4.1 and 13.5) and safari technology preview (17.0). Can you see if the above project works for you? Are you able to give me access to the failing project? If I am not able to reproduce the problem then I am not able to investigate. Thanks! |
Hey @slimbuck, Thanks for the quick reply!
We did implement a quick workaround which chains the wasm basis transcoder's failure into fallback (non-wasm) basis transcoder workers. This seems to be working for us at the moment. Let me know if you can repro with the basis file I provided, otherwise.. umm.. Safari 17 / iOS 17 (beta) wasm regression? |
I can reproduce it in this engine example: https://playcanvas.github.io/#/graphics/texture-basis |
I've logged an issue on webkit https://bugs.webkit.org/show_bug.cgi?id=260252 |
I just tested Safari Tech Preview (Release 179 (Safari 17.0, WebKit 18617.1.8.1)) and the issue is still there. However a workaround for this has been added here: #5657 |
Hello!
We recently upgraded to Playcanvas 1.64.4 and basis transcode has stopped working for some platforms.
(Console errors)
(basis-worker.js)
Our basisInitialize config:
{ “glueUrl":"(some url)/assets/lib/basis/basis.wasm.js", "wasmUrl":"(some url)/assets/lib/basis/basis.wasm.wasm", "fallbackUrl":"(some url)/assets/lib/basis/basis.js", "maxRetries":3, "rgbPriority":["etc1","etc2","astc","dxt","pvr","atc"], "rgbaPriority":["astc","dxt","etc2","pvr","atc"] }
If we force the fallback path (via hard coding wasmSupport to false) instead of compileStreaming / compileManual, our basis images do load properly.
(basis.js)
Let me know if there is any other info you’d like me to gather / follow up on. Any workarounds (other than forcing fallback) would be great!
