New description:

 Summary of the bug:

 If you tried to build FFmpeg with only enable some H.264-related things,
 it will fail to link by this error:

 {{{
 LD      ffprobe_g
 /usr/bin/ld: libavcodec/libavcodec.a(h2645_sei.o): in function
 `ff_h2645_sei_reset':
 /ffmpeg/libavcodec/h2645_sei.c:935: undefined reference to
 `ff_aom_uninit_film_grain_params'
 collect2: error: ld returned 1 exit status
 }}}

 and it will be fixed by cherry-pick
 https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/7aeae8d1ae846302ba1e9955cf64fe83f02b7a57
 to n7.1.1 tag (probably forgot to cherry-pick to 7.1 branch?).

 How to reproduce:

 on Debian 12,

 {{{
 $ ./configure \
         --disable-everything --disable-runtime-cpudetect --disable-network
 --disable-pthreads --disable-v4l2-m2m --disable-avdevice --disable-doc \
         --enable-decoder=h264 --enable-parser=h264 \
         --enable-bsf=h264_metadata --enable-bsf=h264_mp4toannexb --enable-
 bsf=h264_redundant_pps
 $ make
 }}}

 (some options are might be not needed to reproduce it, but error can be
 reproducible with this config)
