stbi_load doesn't work with jpg, data is null #1364

First of all, here's what I already tried: different paths - relative/absolute, checked the JPEG encoding format (it was always baseline), opened pictures through fopen (they open), and of course tried different pictures. Also tried different versions of stb. Always data is null and always stbi_failure_reason gives this error: "unknown image type". At the same time, it works perfectly with png format. There are several images here that I used: |

Tried the first one (in my own codebase, not your test code), it loaded fine for me. What platform are you on and/or what compiler are you using? You could try using fopen to load the file yourself (make sure you open in binary mode), and then use If you're willing to debug it, breakpoint in |

Windows 10/MSVC. I'll try everything you listed and come back here with the results, thanks. |

Okay, I figured out what the problem is. If I directly define implementation in the class where I load the texture, then everything works fine. I have one project referencing to another.. Here's what the solution structure looks like: I'm wondering why png files loaded fine... |

I understand that all this strange behavior is due to a conflict between assimp and your lib. Thanks, good luck! |

It appears assimp uses stb internally, so probably the cleanest way to address this is to define STB_IMAGE_STATIC when including it with STB_IMAGE_IMPLEMENTATION, which makes all the definitions private to the file. but really assimp should do this to avoid causing collisions with clients. |

stbi_load_from_memoryand see if that's any different, but I can't imagine why it would be.If you're willing to debug it, breakpoint in
stbi__err(). Then run until the callstack shows the jpeg decoder (possibly other image formats will be attempted first and generate spurious calls tostbi__err). Then look up one level on the callstack and see what's calling one of thestbi__err*()macros.
