[FFmpeg-devel] [PATCH] lavu/thread: Check HAVE_PTHREAD_SET_?NAME_NP is defined

[post at frankplowman.com]

From: Frank Plowman <post at frankplowman.com>

Check HAVE_PTHREAD_SETNAME_NP and HAVE_PTHREAD_SET_NAME_NP are defined
before using them in macro conditions.  Gets rid of lots of -Wundef
warnings present when building on MacOS since
fd16d8c68cd7b820eda76c407b0645b7cf470efd.
