<flag name="hardcoded-tables">
|
||
|
|
Use pre-calculated tables rather than calculating them on the fly.
|
||
|
|
|
||
|
|
It results in an increase of approximately 15% in the size of libavcodec, the main library impacted by this change.
|
||
|
|
It enables savings in table generation time, done once at codec initialization, since by hardcoding the tables,
|
||
|
|
they do not need to be computed at runtime. However, the savings are often negligible (~100k cycles is a typical number) especially when amortized
|
||
|
|
over the entire encoding/decoding operation.
|
||
|
|
|
||
|
|
Improvements are being made to the runtime initialization, and so over time, this option will have an impact on fewer and fewer codecs.
