let me introduce you to grep

its first argument is what you search for the rest are files in which you
it also takes options like -i for ignoring case

grep -i 'bitstream.*filter' libavcodec/*c

the resulting files are bitstream filters and the bitstream filter core

it should not be hard to write a new by taking one of them as example,
they are all fairly trivial
