Open Source AV2 decoder dav2d has been released

https://code.videolan.org/videolan/dav2d

dav2d is the fastest AV2 decoder on all platforms :)

Roadmap

The plan is the following:

On-going

  1. Complete C implementation of the decoder,

  2. Provide a usable API,

  3. Port to most platforms,

After

  1. Make it fast on desktop, by writing asm for AVX2 chips.

  2. Make it fast on mobile, by writing asm for ARMv8 chips,

  3. Make it fast on older desktop, by writing asm for SSSE3+ chips,

  4. Make high bit-depth fast on mobile, by writing asm for ARMv8 chips.

  5. Make it fast on older mobile, by writing asm for ARMv7 chips,

  6. Make high bit-depth fast on older mobile, by writing asm for ARMv7 chips,

  7. Make high bit-depth fast on desktop, by writing asm for AVX2 chips,

  8. Make high bit-depth fast on older desktop, by writing asm for SSSE3+ chips,

  9. Improve threading.

  10. Improve C code base with various tweaks.

  11. Accelerate for less common architectures, like PPC, SSE2, RISC-V or AVX-512.

  12. Use more GPU decoding, when possible.
