If you enable QSV in obs-studio, the ebuild builds just fine but it cannot encode videos unless you also install media-libs/intel-mediasdk. Reproducible: Always Steps to Reproduce: 1. install obs-studio with USE=qsv 2. start obs-studio on a CPU with Intel iGPU 3. switch stream/recording to Intel QSV 4. error occurs Actual Results: error is shown in the log: 01:28:44.956: >>> app not on intel GPU, fall back to old qsv encoder 01:28:44.956: [qsv encoder: 'advanced_video_recording'] settings: 01:28:44.956: codec: H.264 01:28:44.956: rate_control: VBR 01:28:44.956: target_bitrate: 8000 01:28:44.956: max_bitrate: 12000 01:28:44.956: Lookahead Depth:60 01:28:44.956: target_usage: TU4 01:28:44.956: profile: high 01:28:44.956: keyint: 0 01:28:44.956: latency: normal 01:28:44.956: b-frames: 3 01:28:44.956: fps_num: 60 01:28:44.956: fps_den: 1 01:28:44.956: width: 2560 01:28:44.956: height: 1440 01:28:44.956: [qsv encoder: 'advanced_video_recording'] debug info: 01:28:44.960: Failed to initialize MFX 01:28:44.960: [qsv encoder: 'msdk_impl'] Specified object/item/sync point not found.

The next non-patch release should have CMake options tweaked to handle these better (will be in 9999 soon), and if there is want for experimenting more with it already, can always flip it using 'MYCMAKEARGS="-DENABLE_NATIVE_NVENC=ON"'. 1. https://github.com/obsproject/obs-studio/issues/11009 Closes: https://bugs.gentoo.org/936826 Closes: https://bugs.gentoo.org/938022 Closes: https://github.com/gentoo/gentoo/pull/37755 Signed-off-by: Jimi Huotari <chiitoo@gentoo.org> media-video/obs-studio/Manifest | 2 + media-video/obs-studio/obs-studio-30.2.3.ebuild | 274 ++++++++++++++++++++++++ media-video/obs-studio/obs-studio-9999.ebuild | 9 +- 3 files changed, 282 insertions(+), 3 deletions(-)
