hevc: Avoid using LOCAL_ALIGNED for 4 byte alignment
Merged-by: James Almer <jamrial@gmail.com>
|
|
The data types within the MvField struct themselves imply 4 byte alignment.

hevc: rename hevc.[ch] to hevcdec.[ch]
Merged-by: Clément Bœsch <u@pkh.me>
|
|
Those values are decoder-independent and are also use by the VA-API
encoder.
|
|
This is more consistent with the rest of libav and frees up the hevc.h
name for decoder-independent shared declarations.

Factor out the parameter sets into a separate struct and use it instead.
This will allow us to reuse this code in the parser.

hevc_mvs: initialize the temporal MV in case of missing ref
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
The spec requires this.
Fixes uninitialized reads on some samples.
Remove now unnecessary initialization of the whole merge candidate list.
|
|
The caller expects the MV to always be initialized.
