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

ERROR:

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:

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

SOLUTION:

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.
