Forgot to write the commit message. Amended with the following: > This commit allows the existing decode infrastructure to be used by > non-native Vulkan hwaccels, such as purely compute-based > implementations, or hybrid CPU-GPU implementations. > Using the existing infrastructure allows to deduplicate large chunks > of management, initialization, and thread context synchronization > code.The code using it is still largely untested, so it may change with the next version I post, but nothing major - this mostly if()s out any native Vulkan decode calls from init. Posting this because the changes to frame_params+init were too obtrusive to rebase this piece of code on top.
