Changes for 1.0.0 'Peregrine falcon':
|
|
-------------------------------------
|
|
|
|
1.0.0 is a major release of dav1d, adding important features and bug fixes.
|
|
|
|
It notably changes, in an important way, the way threading works, by adding
|
|
an automatic thread management.
|
|
|
|
It also adds support for AVX-512 acceleration, and adds speedups to existing x86
|
|
code (from SSE2 to AVX2).
|
|
|
|
1.0.0 adds new grain API to ease acceleration on the GPU, and adds an API call
|
|
to get information of which frame failed to decode, in error cases.
|
|
|
|
Finally, 1.0.0 fixes numerous small bugs that were reported since the beginning
|
|
of the project to have a proper release.
