FFmpeg使用v4l2时出错

我尝试签出ffmpeg以按如下方式构建它：

git克隆ffmpeg

cd-ffmpeg

/configure--disable-asm--disable-v4l2-m2m--disable indev=v4l2--disable outdev=v4l2

制造

但我得到以下错误：

libavcodec/v4l2_m2m_enc.c:51: warning: braces around scalar initializer

知道如何继续吗？

我对--disable-x86asm（而不是--disable-asm）也有同样的问题。这可能是环境问题吗？配置步骤生成的输出仍然将v4l2_m2m列为提供硬件加速的外部库是否存在需要更新的linux驱动程序？我在路径中添加了/usr/include。这将确保找到/usr/include/linux/videodev2.h。但这仍然没有帮助我注意到，在我的/usr/include/linux/videodev2.h中，结构v4l2_ext_控件被定义为：结构v4l2_ext_控件{u32 id；uuuu32 size；uuu32 reserved2[1]；union{uuuuus32值；uuus64值64；字符*字符串；uuu8*p_u8；uu16*p_16；uuu32*p_32；void*ptr；}；}}uuuu属性（（压缩））；
