Hello, I'm a bit late to the party, but I'm interested in proposing a GSoC project on VVC x86 SIMD optimization. This was on the 2025 ideas list but there are currently no SIMD overrides for itx or intra_pred in avcodec/x86/vvc/dsp_init.c, only ALF and inter prediction have x86 assembly.
I would like to propose implementing: -AVX2 inverse transforms for DCT-II, DST-VII, and DCT-VIII -Intra prediction for DC, planar, and angular modes -Corresponding checkasm tests and benchmarks For qualification, I'm currently working on a checkasm test for VVC inverse transforms (tests/checkasm/vvc_itx.c). I've emailed Nuo Mi about mentoring since he mentored the VVC SIMD projects in 2023 and 2024. If anyone else is interested in mentoring or has thoughts, I'd appreciate it. Best, Hankang Li _______________________________________________ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
