[FFmpeg-devel] [Question]Inquiry Regarding RISC-V RVV Optimization for HEVC Decoding in FFmpeg

[yunfei_zhou--- via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

Hi all,
I hope this message finds you well.
My name is Yunfei Zhou, and I am a Software Development Engineer at Alibaba DAMO Academy, where I focus on video coding and decoding optimization.
We are currently exploring vectorization optimizations for HEVC decoding using the RISC-V Vector Extension (RVV) and are eager to contribute our work to the FFmpeg community. 
Before proceeding, we would like to understand whether there are any existing or ongoing efforts in this area to avoid duplication and, ideally, align or collaborate with current initiatives.
Could you kindly share an update on the current status of RISC-V RVV support for HEVC decoding in FFmpeg? Specifically, we’d appreciate any information regarding:

 * 
Recent developments or patches related to RVV-based HEVC optimizations,

 * 
Planned future work in this domain, and

 * 
Available documentation or resources that could help us better understand the existing codebase and optimization strategies.
Thank you very much for your time and support. We look forward to contributing to and learning from the FFmpeg community.
Best regards,
Yunfei Zhou
Alibaba DAMO Academy
