Opus deemphasis is not included as it (IMHO) involves too many unknowns to write a good implementation without benchmarking. This post-filter implementation merely vectors the scalar product. It does purposed not vector the memory accesses to avoid reconfiguring the vector unit too often. It might be possible to work it out, but again, I cannot really tell without real hardware The following changes since commit b0c7352cd494c88d33f032be60b5e1c4e8b092a0: avcodec/mjpegdec: Fix compilation (2022-09-30 19:30:29 +0200) are available in the Git repository at: git.remlab.net:git/ffmpeg.git rvv-vtype for you to fetch changes up to 1aa3efa0563aaaed376a35c0e7c9fe53089c3a7e: lavc/opusdsp: RISC-V V (256-bit vectors) postfilter (2022-10-01 15:24:42 +0300) ---------------------------------------------------------------- Rémi Denis-Courmont (4): QEMU hack lavc/opusdsp: RISC-V V postfilter lavu/riscv: helper macro for VTYPE encoding lavc/opusdsp: RISC-V V (256-bit vectors) postfilter libavcodec/opusdsp.c | 2 ++ libavcodec/opusdsp.h | 1 + libavcodec/riscv/Makefile | 2 ++ libavcodec/riscv/opusdsp_init.c | 49 +++++++++++++++++++++++++++ libavcodec/riscv/opusdsp_rvv.S | 59 ++++++++++++++++++++++++++++++++ libavutil/riscv/asm.S | 75 +++++++++++++++++++++++++++++++++++++++++ libavutil/riscv/cpu.c | 2 +- 7 files changed, 189 insertions(+), 1 deletion(-) create mode 100644 libavcodec/riscv/opusdsp_init.c create mode 100644 libavcodec/riscv/opusdsp_rvv.S
