Hi! You have 2 options: 1) write pthread emulation for your target system. We wrote one for windows native threads, but others should be straightforward. 2) if you want thread-less, that's possible (single-threaded performance shows 1080p is easy, and on high-end systems even 4K single-threaded might be doable), which basically just involves putting the two functions in thread_task.c under #if HAVE_THREADS, along with any coded calling pthread_() functions or using pthread_ types from <pthreads.h>, and then enforcing that Dav1dSettings.n_{tile,frame}_threads is always 1 (that means it won't ever enter these codepaths). Then, you always get single-threaded and (p)thread-less decoding. Feel free to come on IRC, happy to help you dive into this, it's not very difficult.
