So, here are some patches:
copy_extradata_3.diff modifies ffmpeg.c to copy the extradata from the
                       input codec to the output codec (instead of just
                       copying a pointer to the extradata), as suggested
                       above
improve_mp4toannexb_2.diff modifies the mp4toannexb BSF to convert the
                            extradata. The previous patch is needed,
                            otherwise there are problems with "-vcodec copy"
                            (see previous email)
use_bsf_for_sdp.diff uses the previous mp4toannexb BSF improvement to
                      correctly print the SPS and PPS in the SDP, even when
                      the bitstream is in "AVC" syntax
