For those in file ffmpeg  try to add const in front of AVCodec at lines
162, 193, 1849 and  1887?

For ffmpeg.C.. Try to add const to same AVCodec but obviously in some cases
it will be at lines *before* indicated (where for example *dencoder of this
type was  declared. Like for line 3895 you will find declaration at line
3878.. Not sure about

ffmpeg.C:3654:77: error: cannot convert ‘int*’ to ‘size_t*’ {aka ‘long
unsigned int*’}

May be try to change those int types in function to size_t or something?
