Hi,
accelerated encoding is currently not implemented (patches welcome).
also the decoder needs some refinement, we had to deactivate it due to
issues with different hardware limitations (alignments, ...) that need
to be considered when activating it.

Hi all
I am a development engineer for a GPU manufacturer. Now I want to adapt our
GPU() to the freerdp project to provide hardware accelerated encoding and
decoding functions.
Our target operating system is Linux, the target version of freerdp is
2.2.0, and our GPU supports VAAPI. We try to start the rdp session by
running the freerdp server/client like this:
*freerdp-shadow-cli /port:8089 -auth*
*xfreerdp /gfx:avc420 10.10.20.102:8089 <http://10.10.20.102:8089>*
We see that the client's decoding uses our GPU for hardware acceleration
through vaapi; but for encoding, hardware acceleration is not used, and
software encoding (libx264) is used.
Looking at the source code of freerdp (h264_ffmpeg.c), we can see that
there is a path to use vaapi for hardware acceleration in decoding
(libavcodec_decompress function), but there is nothing related to hardware
acceleration in encoding (libavcodec_compress function).
So, my question is whether freerdp only supports decoding hardware
acceleration and does not support encoding hardware acceleration?
