The include path is:
timer.h =>
<sys/ioctl.h> =>
<linux/termios.h> =>
<asm/termios.h> =>
<asm-generic/termios.h> =>
<asm/termbits.h> =>
<asm-generic/termbits.h> =>
<asm-generic/termbits-common.h>
#define B0 0x00000000
#define B50 0x00000001
#define B75 0x00000002
The issue has occurred multiple times, e.g.,
commit f0f596dbc6b45b544d2d2d4fb78c0a2bdc3e6eb1
avutil/internal: remove timer.h again
timer.h has been removed from internal.h, and then added back with
3e6088f for convenience. This patch removed it again for the
following reasons:
1. Only includes what's necessary is a common and safe strategy.
2. It fixed some build errors on Android:
a. libavutil/timer.h includes sys/ioctl.h, and ioctl.h includes
termios.h on Android.
b. termios.h reserves names prefixed with ‘c_’, ‘V’, ‘I’, ‘O’, and
‘TC’; and names prefixed with ‘B’ followed by a digit.
c. libavcodec uses B0 B1 and so on as variable names a lot. So
the code failed to build with --enable-linux-perf, or
--target-os=Linux.
