Compilation error with Qt+USING_GLES2 (and unrelated FFmpeg 4 warnings) #11495
Comments

FFmpeg doesn't really maintain backwards compatibility or a good API change log. You should always assume that updating ffmpeg will break anything that uses it which isn't a simple track based video/music player. We compile and test against a stock 3.0.2 and don't really gain anything from changes in newer versions (we mainly use the obscure codec the PSP uses, which hasn't had changes in FFmpeg in years.) That said, pull requests accepted. -[Unknown] |

Hm. That's because I don't see that error quoted originally, but I do see -[Unknown] |

changed the title
ffmpeg 4.0 support was fixed in 70c54a7, so I've looked at "Full build log: here" and quoted the actual error.

Okay, hopefully #11507 fixes this, then. -[Unknown] |

Hello everyone.
What happens?
PPSSPP-1.7does not compile agaistFFmpeg-4.0.2whenUSING_GLES2option is on:What should happen?
No errors.
What hardware, operating system, and PPSSPP version? On desktop, GPU matters for graphical issues.
It's a test build on RPM build system on Fedora 28 x86_64.
