Summary:
libjpeg-turbo, a multimedia codec library, has a code acceptance policy that seems to involve money changing hands. Many popular distributions use this upstream. Thus to get this support integrated, pay the maintainer to write or accept RISC-V Vector support.
- Software multimedia acceleration is generally achieved through heavy use of optimized SIMD assembly. For most on device use cases, there is a minimal threshold of encoding or decoding performance that must be reached to be viable, e.g., decoding audio even 95% real-time is insufficient as stuttering audio makes communication impossible. Assuming there will be hardware offload is also insufficient as many services require device compatibility across a large set of formats before they will deploy into a market.
- RISE members identified several multimedia libraries when initially scoping the list of prioritized projects System Libraries Projects. These include FFmpeg, acc, flac, libvpx, libjpeg-turbo, libpng, libhevc, libdav1d, etc.
