[FFmpeg-user] FFMPEG compilation errors

[Sun Fire]

Hi,
      I am trying to cross compile FFMPEG with gcc for arm.   gcc does not seem to find the discrete member in v412_frmsizeenum. Where ( in which file) has this structure 
v4l2_frmsizeenum been defined ? Any idea why gcc is not getting the definition of discrete ? 
 
Other than v412.c,  I could not find any reference to v412_frmsizeenum. Is there something I am missing here ? 
 
v4l2_frmsizeenum
