mpv does not work if opengl32.dll presents from mesa #7530

Opps my bad. I was trying to update it before sleep and forgot that. The issue is not related with the mpv version. |
|
uh why use mesagl with mpv ?!? does it fail with desktop opengl. |
the problem is that if it's installed it gets used, even if not intended. |
|
Hmm could we not place the dll's in some subdir under bin ? that should avoid this. |
|
Ideally we'd let the user pick which implementation is used, probably via package installation. Obviously it would need to work on both scenarios here. |
|
Should be easy enough to just copy the dll's from say bin/mesa to bin if a user prefers to use the mesagl binaries no ? |
|
Adding a system-opengl package that is mutex with mesa sounds like a better idea to me personally. |
|
Also a possibility. 👍 |
|
I tried to reproduce but I couldn't using this MSYS2 environment: |
|
OK, am I the only one with this issue? Can anyone here reproduce it in your machine? |
|
I am using Intel G2020 (yeah! it's very much old). |
I don't know. It should be able to work as your CPU should be able to run anything up to and including AVX. Are running MSYS2 in a VM or something? |
|
No VM, just Windows on bare metal. So, where did you get the hint about sse3? Just curious. |

I thought msys2 does not enable any CPU specific instructions. OK, then it's conclusion time.

Your CPU does supports all the extensions enabled by |

@Biswa96 @mati865 @revelator @lazka @mingwandroid I finally figured out what's going on here. I looked again at Intel G2020 specs and it looks like it doesn't support AVX. mingw-w64-x86_64-mesa includes swr driver which unfortunately is plagued by issues with AVX usage leaking into common code: |
|
It's good to see I'm not the only one 😅 OK, then reopening this issue. Waiting for fixes in mesa upstream... |

All Pentium CPUs do no support AVX but still they cover more features than |
Recently I have seen this kind of thing with |
|
some of the later models do infact support AVX but support came much later than on the core models. which kinda sucks when something requires this extension :/ and you have one of the older models |
|
|
Oh, I wasn't aware about it. |
|
if that's so, I think gcc needs to update their docs https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html as a note, on 3 machines with different gcc versions all show the same thing with |
Steps:
Workaround: Remove or rename the
/mingw64/bin/opengl32.dllfile.Thoughts: I think opengl32.dll should be from System32. But as the opengl32.dll presents in
/mingw64/bin/folder,mpv.exeloads it from that path first instead of the System32 one. Also mesa-demos has this same issue.mingw-w64-mesa package maintainer, @pal1000 any hint about this issue?
@lazka mpv is not updated. PKGBUILD shows version 0.33.0 but pacman shows 0.32.0-3
