VP8 encoding and GPU support

[jongerenchaos]

For now i encode with vlc a vp8 file (from vp8/webm to vp8/webm with a logo overlay) on linux and my processor went to te 100% (if i want to encode it realtime).

Is there a way that i can use the GPU for the file re-coding for vp8 files or is this only for the following codecs (without display output, only vp8 file to re-encoded vp8 file)?:
h263_vaapi mpeg2_dxva2 vc1_dxva2
h264_dxva2 mpeg2_vaapi vc1_vaapi
h264_vaapi mpeg2_vdpau wmv3_dxva2
mpeg1_vdpau mpeg4_vaapi wmv3_vaapi

I think VAAPI and DxVA2 are only for GPU-decoding, not encoding.

DSP-assisted encoding would either require FFmpeg/libav support, or a dedicated codec plugin in VLC.
