Tvheadend

Hi

I try to build tvheadend with transcoding and get the following error on Unbuntu 14.10

/usr/lib/x86_64-linux-gnu/libavcodec.a(vaapi.o): In function `ff_vaapi_mpeg_end_frame':
(.text+0x850): undefined reference to `vaUnmapBuffer'
collect2: error: ld returned 1 exit status
Makefile:410: recipe for target '/root/tvheadend/build.linux/tvheadend' failed
make: *** [/root/tvheadend/build.linux/tvheadend] Error 1

I used ./configure --enable-libffmpeg_static
