FIX:- make: *** [libavdevice/v4l.o] Error 1


While installing FFMPEG on a server when we run “make” after “./configure” it gives following error:

math-errno       -c -o libavdevice/v4l.o libavdevice/v4l.c
In file included from libavdevice/v4l.c:32:
/usr/include/linux/videodev.h:56: error: syntax error before "ulong"
/usr/include/linux/videodev.h:72: error: syntax error before '}' token
libavdevice/v4l.c: In function `grab_read_header':
libavdevice/v4l.c:77: error: storage size of 'tuner' isn't known
libavdevice/v4l.c:141: error: invalid application of `sizeof' to incomplete type `video_tuner'
libavdevice/v4l.c:148: error: invalid application of `sizeof' to incomplete type `video_tuner'
libavdevice/v4l.c:77: warning: unused variable `tuner'
make: *** [libavdevice/v4l.o] Error 1


This problem can be fixed by disabling v41 and v42 for FFMPEG. This can be done when we run “./configure” for FFMPEG

./configure --enable-libmp3lame --enable-libvorbis --disable-mmx --enable-shared --disable-demuxer=v4l --disable-demuxer=v4l2

Once this has been completed run “make” and “make install” to install FFMPEG.
