Setting the priority to "minor" was possibly a mistake...

[ligh_de]

3 weeks without even the slightest reply to a bug which lets the compilation fail.

If you want to drop x86 (32b) support, please tell us at least that.

[XiangLi]

Thanks for the report. VTM does not work properly in 32-bit due to big amount of memory used. Although We have an MR on memory reduction, it may not solve all the issues with 32-bit. It is suggested to test with 64-bit compiler. Fix and improvement for 32-bit are appreciated.

[ligh_de]

Thank you. I will forward to the "media-autobuild suite" staff that it will be safer to restrict building VVC for 64-bit target only, until there may ever be a patch to re-enable 32-bit builds.

[ksuehring]

Your expectations may be wrong here. This is a reference software implementation intended as an example to base your own implementations on. This is very experimental software, being used to verify coding algorithms and their performance. This is not intended to be a final codec implementation suitable to be used in any form of product.

I think we never had proper 32-bit support. Even with the HM reference software for HEVC, which was the base for this code, it was not possible to encode any bigger image formats without hitting the 2GB border.

I don't think, we will be able to achieve that with VTM, even with the memory reduction that Xiang mentioned.

We are also targeting the build platforms that are commonly in use by the people contributing to the standard. See the software manual for a full list.

We added experimental support MSYS2 build on request, but we also were clear that is nothing we can support, because we just don't use platform ourselves and don't have build nodes for it. There is no testing for newer compilers, etc.

For bug fixes we are depending on volunteers looking into the issues and providing patches.

Although we encourage testing the software outside the common test conditions, these conditions are what is currently being tested for all our software releases.

[ligh_de]

Thank you for clarifying the circumstances.

I do remember that already HEVC HM (and x265 subsequently) struggled with the platform limits of 32-bit addressing. I see that VVC will even more so.

Now that this statement has been given, the MABS staff knows that disabling its building for x86 is just how it is supposed.
