 AMF is effectively supported by FFmpeg to significantly speed up video encoding, decoding, and transcoding via AMD GPUs.
+== Decoding ==
+AMD supports hardware decoding via DirectX in FFmpeg. Currently supports DX9 and DX11 in FFmpeg.
+
+Hardware decoding via DX9
+
+{{{
+ffmpeg -hwaccel dxva2 -i input.mkv output.yuv
+}}}
+
+**Note:** Currently AMD hardware doesn’t support **AV1 elementary stream decoding via DX9**. So, this command line is not applicable for AV1 bitstream as input.
+
+Hardware decoding via DX11
+
+{{{
+ffmpeg -hwaccel d3d11va -i input.mkv output.yuv
+}}}
+
+In the above command line, “input.mkv” is only an example. The AMD hardware accelerated decoder supports most widely used containers and video elementary stream types. The following table lists detailed information about the widely used containers and video elementary streams which the AMD hardware accelerated decoder supports.

 == Encoding ==
 Currently AMF encoder supports H.264/AVC, H.265/HEVC, AV1 encoder. FFmpeg uses `_amf` as the postfix for the AMF encoder names. The command lines shown below may use `h264_amf`, and should be replaced by `hevc_amf` for H.265/HEVC encoder and `av1_amf` for AV1 encoder.
