Search RVV on code.ffmpeg.org https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls?state=open&type=all&labels=&milestone=0&project=0&assignee=0&poster=0&sort=&q=rvv > > * > 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.

General document on contributions https://www.ffmpeg.org/developer.html#Introduction I have a simple summary on asm optimization https://gist.github.com/quink-black/316ac42e0482f4158dd7df3003794576 > Best regards, > Yunfei Zhou > Alibaba DAMO Academy > _______________________________________________ > ffmpeg-devel mailing list -- [email protected] > To unsubscribe send an email to [email protected] _______________________________________________ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
