Commit Message

Lynne Dec. 3, 2021, 4:06 p.m. UTC
The issue is that if ffmpeg is compiled without Vulkan, and an API 
user includes and uses the functions exposed in hwcontext_vulkan.h,
then a linking error will happen, as the hwcontext_vulkan.c file has
not been compiled.

Move the functions to another file, and make it always compiled. The
functions do not use any Vulkan functions.

Patch attached.

then a linking error will happen, as the hwcontext_vulkan.c file has
not been compiled.

Move the functions to another file, and make it always compiled. The
