Vivekanand	b092ee701f	avformat/allformats: Making av_register_all() thread-safe. When multiple threads tries to call av_register_all(), the first thread sets initialized to 1 and do the register process. At the same time, other thread might also call av_register_all(), which returns immediately because initialized is set to 1 (even when it has not completed registering codecs). We can avoid this problem if we set initialised to 1 while exiting from function. Github: Closes #196	9 years ago

Nicolas George	8b05a7ffe4	lavf/udp: fix dead code. Since `d607861`, service can not be NULL, only "0". An UDP address with neither local port nor address leaves both service and node to their default value, and POSIX specifies that they are not allowed to be both NULL; "0" is equivalent to an unspecified port for all currently known protocols.

Neil Birkbeck	785038c92c	lavu: Adding ARIB STD-B67 (hybrid log-gamma) enum value and transfer function. Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma) based on the standardization in ARIB STD-B67: http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf The choice of enum value of 18 is consistent with HEVC: http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481 And also with latest proposal for color format in mkv: https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal The implementation assumes a nominal input range of [0, 1], which is consistent with HEVC.
