[Libav-user] HW Acceleration

I would like to compile ffmpeg including HW accelleration.

My configure call is as follow:

./configure --prefix=/usr --disable-nonfree --disable-gpl
--disable-encoders --disable-muxers --disable-debug --disable-amd3dnow
--disable-amd3dnowext --enable-hwaccels --enable-vaapi --enable-vdpau
--enable-runtime-cpudetect --enable-shared --disable-devices

I can see following lines after I run ./configure

Enabled hwaccels:
h263_vaapi              mpeg2_vaapi             vc1_vaapi
h264_vaapi              mpeg4_vaapi             wmv3_vaapi

Now my question is do I get HW acceleration directly inside the
libavcodec or do I have to manage this with special hw_accel contexts?

thx for answer,
Robert Grasböck
