All source files match their path from the library's source archive.
|
|
|
|
|
|
|
|
|
|
Currently, we only use the vp8 and vp9 portion of the library, and only on x86
|
|
|
|
|
based platforms. If this changes, configuration files will most likely
|
|
|
|
|
need to be updated.

AVX2 must be disabled on Linux due to the use of yasm 1.1 on the build bots.
|
2015-11-17 09:47:36 +03:00
|
|
|
Once yasm is upgraded to 1.2 or later, AVX2 code could be re-enabled.
|
2016-02-16 04:05:12 +03:00
|
|
|
Add --disable-avx2 to configure on those platforms.
