More details:

In function VASupportedProfiles::GetSupportedVAProfiles,
https://github.com/chromium/chromium/blob/master/media/gpu/vaapi/vaapi_wrapper.cc#L571

const int max_profiles = vaMaxNumProfiles(va_display_);
vaMaxNumProfiles will return (PIPE_VIDEO_PROFILE_MPEG4_AVC_HIGH -
PIPE_VIDEO_PROFILE_UNKNOWN) in mesa.

 int num_supported_profiles;
  VAStatus va_res = vaQueryConfigProfiles(va_display_, &supported_profiles[0],
                                          &num_supported_profiles);
  VA_SUCCESS_OR_RETURN(va_res, "vaQueryConfigProfiles failed", false);
  if (num_supported_profiles < 0 || num_supported_profiles > max_profiles) {
    LOG(ERROR) << "vaQueryConfigProfiles returned: " << num_supported_profiles;
    return false;
  }

(num_supported_profiles > max_profiles) is true when using RAVEN APU, so
hardware decoder is failed.
