 Hi,

 I'm trying to use the hevc_amf encoder to transcode some h264 videos I
 have. Even though the h264_amf encoder works, hevc_amf always fails with
 the error code 10 no matter what I do. I compiled my ffmpeg build from the
 git-master with vulkan, amf and openCL enabled. The GPU is a 5700XT and I
 tried it in both Ubuntu and Arch but the error didn't go away.

 Here is the command and the output,  sample.mp4 was a h264 encoded file
 that was also produced by ffmpeg. I tried a vp8 webm as an input as well
 but the error was the same.

 }}}

 Is this caused by my configuration being faulty or is there a problem with
 the hevc_amf encoder? Since h264_amf encoder works and hevc_amf gets
 successfully initialized I don't think it is an issue with my Linux
 installation.
