Para contornar, devem ser realizadas as alterações abaixo nos seguintes arquivos:

ffmpeg_frame.c

Substituir as linhas que contém PIX_FMT_RGBA32 por PIX_FMT_RGB32.

ffmpeg_movie.c

linha 311: SUBSTITUIR list_entry *le; POR zend_rsrc_list_entry *le;
linha 346: SUBSTITUIR list_entry new_le; POR zend_rsrc_list_entry new_le;
linha 360: SUBSTITUIR hashkey_length+1, (void *)&new_le, sizeof(list_entry), POR hashkey_length+1, (void *)&new_le,sizeof(zend_rsrc_list_entry),

Após, só instalar com os comandos abaixo:

cd ffmpeg-php-0.6.0
./configure --enable-skip-gd-check
make
make install
