Hello,
I'm very new to libavcodec and the source, but I saw that the newest
version of VLC player mentioned GPU decoding in its release notes.
This made me curious about a few things:
1. Does libavcodec provide gpu decoding support itself? And if so:
2. Is this done via OpenGL shaders, OpenCL, or CUDA?
3. What codecs are supported?
4. Will gpu encoding support be added in the future?
5. How much faster is decoding/encoding on the gpu?
My apologies if this was asked before, but I didn't see any info in
the archives. Thanks in advance.

From what I gathered from the source code and the configure script, the
only two gpu accelerated portions of use are in the vaapi, vdpau, and
dxva2 sections. I have written CUDA before and didn't see any of it in
the source.
