- 3.0 has the 128 pixels padding elsewhere
|
||||
- 3.0 has an extra parameter for add_integer_with_range()
|
||||
- 3.0 was setting i_extra_picture_buffers further down in the code
|
||||
- 3.0 uses 16 threads max

|

Subject: [PATCH 2/2] dav1d: limit the number of extra frames needed by the
|
||||
decoder
|
||||
|
||||
The i_extra_picture_buffers is used to add pictures to the pool that the core
|
||||
will allocate. dav1d is actually using n_threads frames. And the core is
|
||||
allocating 10 frames per default for AV1. So we need to add the missing ones.
|
||||
|
||||
(cherry picked from commit a32031dc0f5f32083fc54a21397bce732742ccbe) (rebased)
|
||||
rebased:
|
||||
- the code dav1d 1.0.0 in 3.0 uses different max versions
