* avutil/internal, swresample/audioconvert: Remove cpu.h inclusionsAndreas Rheinhardt2021-07-22
| | | | | | | | | | These inclusions are not necessary, as cpu.h is already included wherever it is needed (via direct inclusion or via the arch-specific headers). Also remove other unnecessary cpu.h inclusions from ordinary non-headers. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* w32pthreads: always use Vista+ API, drop XP supportwm42017-12-26
| | | | | | | | | | | This removes the XP compatibility code, and switches entirely to SWR locks, which are available starting at Windows Vista. This removes CRITICAL_SECTION use, which allows us to add PTHREAD_MUTEX_INITIALIZER, which will be useful later. Windows XP is hereby not a supported build target anymore. It was decided in a project vote that this is OK.

* lavfi: fix race when func rets holder is NULLClément Bœsch2017-03-28
| | | | | | | If ret is NULL, a dummy common holder is created to hold *all* the parallel function returns, which gets written concurrently. This commit simplify the whole logic by simply not writing to that holder when not set.

| * pthread: Fix deadlock during thread initializationDerek Buitenhuis2013-10-13
| | | | | | | | | | | | | | | | | | | | Sometimes, if pthread_create() failed, then pthread_cond_wait() could accidentally be called in the worker threads after the uninit function had already called pthread_cond_broadcast(), leading to a deadlock. Don't call pthread_cond_wait() if c->done is set. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
