Hello, After emerging media-libs/nv-codec-headers-12.1.14.0 , compiling ffmpeg with nvenc USE flag will fail with: src/libavcodec/nvenc.c: In function ‘nvenc_setup_hevc_config’: src/libavcodec/nvenc.c:1373:9: error: ‘NV_ENC_CONFIG_HEVC’ has no member named ‘pixelBitDepthMinus8’ 1373 | hevc->pixelBitDepthMinus8 = IS_10BIT(ctx->data_pix_fmt) ? 2 : 0; | ^~ Reproducible: Always Steps to Reproduce: 1. emerge >=media-libs/nv-codec-headers-12.1.14.0 2. emerge =media-video/ffmpeg-6.1.1-r5::gentoo with nvenc USE flag Actual Results: not compiling Expected Results: compiling The issue is explained quite well here: https://www.linuxquestions.org/questions/slackware-14/requests-for-current-next-15-0-15-1-a-4175706801/page274.html#post6493753 In short, the issue is fixed upstream and included in ffmpeg 7.0, which however is not in portage for now. I do not know about upstream policies of backporting so either a patch should be added to the ebuild, or wait for backport, or just bump to 7.0. I didn't try but I guess emerging without nvenc USE flag would work, and/or using an older media-libs/nv-codec-headers .
Odd, it doesn't fail for me, and it shouldn't. [ebuild R ] media-libs/nv-codec-headers-12.1.14.0 [ebuild R ] media-video/ffmpeg-6.1.1-r5 USE="... nvenc .." The $URL (and the github commit) seems to implies it's an issue introduced with nv-codec-headers-12.2 or so but it hasn't been added to the tree yet and this is 12.1 The fix, in fact checks for if the version is >12.2 and does nothing otherwise // SDK 12.2 compile time feature checks #if NVENCAPI_CHECK_VERSION(12, 2) Do you have other newer headers somewhere?
(In reply to Ionen Wolkens from comment #1) > Do you have other newer headers somewhere? (not that ffmpeg ebuild couldn't prepare for this by either backporting or putting an upper bound for older branches, so it doesn't make this bug invalid if so)
Whoops! That's right, I currently have installed: media-libs/nv-codec-headers-12.2.72.0::stefantalpalaru I got fooled by the fact that i've looked in /var/log/emerge.log for recent updates and only ::gentoo packages are written there, for some reason. Well, in case >=media-libs/nv-codec-headers-12.2 gets added to ::gentoo, we already know about this. Sorry for the inconvenience :)
I can't reproduce anymore with =dev-util/nvidia-cuda-toolkit-12.5.0::gentoo.
