From 6408745f54ada32bad44227e6b4173e46641afaa Mon Sep 17 00:00:00 2001 From: q66 Date: Tue, 11 Nov 2025 18:12:01 +0100 Subject: [PATCH] fix posix ioctl on musl The libv4l2 is built with posix ioctl but to make it known to the header the macro needs to be defined which is unfortunate. ffmpeg had it work for a while but then it broke when this commit was introduced: https://github.com/FFmpeg/FFmpeg/commit/5fea5e3e11d6ff425db48f44489916399822aece due to the macro previously being accidentally defined [ismael@sourcemage.org: v4l-utils 1.32 renamed the macro the header checks from HAVE_POSIX_IOCTL to LIBV4L_HAVE_POSIX_IOCTL, so define both to work with old and new versions.] Upstream-Status: Unknown Signed-off-by: Ismael Luceno --- libavdevice/v4l2.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/libavdevice/v4l2.c b/libavdevice/v4l2.c index c38ecbb..3457b43 100644 --- a/libavdevice/v4l2.c +++ b/libavdevice/v4l2.c @@ -49,6 +49,10 @@ #include #if CONFIG_LIBV4L2 +#if HAVE_IOCTL_POSIX +#define HAVE_POSIX_IOCTL +#define LIBV4L_HAVE_POSIX_IOCTL +#endif #include #endif
