2a73404558 avutil/channel_layout: AV_CH_LAYOUT_6POINT1_BACK not reachable in parsing
Trying to make heads and tails out of DTS 6.1 I can across this typo.

I also noticed that this wiki page is incorrect or misleading, the
channel order for 6.1 given does not match the source code.  At the
least it should be clarified that the layout given does not apply to
DTS.  https://trac.ffmpeg.org/wiki/AudioChannelManipulation

5ae4842122 avutil/file_open: avoid file handle inheritance on Windows
Avoids inheritance of file handles on Windows systems similar to the
O_CLOEXEC/FD_CLOEXEC flag on Linux.

Fixes file lock issues in Windows applications when a child process
is started with handle inheritance enabled (standard input/output
redirection) while a FFmpeg transcoding is running in the parent
process.

Links relevant to the subject:

https://msdn.microsoft.com/en-us/library/w7sa2b22.aspx

Describes the _wsopen() function and the O_NOINHERIT flag. File handles
opened by _wsopen() are inheritable by default.

https://msdn.microsoft.com/en-us/library/windows/desktop/ms682425%28v=vs.85%29.aspx

Describes handle inheritance when creating new processes. Handle
inheritance must be enabled (bInheritHandles = TRUE) e.g. when you want
to pass handles for stdin/stdout via lpStartupInfo.
