We tried your video clip and found that "-qvbr_quality_level 51" produces highest quality and "-qvbr_quality_level 1" produces lowest quality. If you see the issue (no effect), please provide output clips...

Thanks for bringing this in. There is a dilemma here: it will be inconvenient for AMF dev team to change the sample code the way you suggested because a good...

Yes, documentation needs to be updated, will ask for it. Multi-instance/split frame is available for HEVC and controlled by AMF_VIDEO_ENCODER_HEVC_MULTI_HW_INSTANCE_ENCODE. Note: that currently it will work for CQP bitrate control...

AMF runtime SO and some other related SOs should match VCN FW and should be installed all-together with driver package. I assume they are already installed on EC2. I am...

I can only tell that installing FW into container has no effect as FW is loaded to HW during system boot time. AMF relies on other SOs from driver package...

AMF is not standalone SO but part of driver package. At this point AMD supports only certain set of distros and x86_64 CPUs. https://www.amd.com/en/support/download/linux-drivers.html

Based on version you are trying non-yet released driver. Not sure how could you get it via Windows Update.

At this point AMF color converter doesn't support YUV-8 (NV12) to YUV-10 (P010) or opposite. We are working on this.

At AMF there is no enforcement or such. There are three related parameters in VUI header for H264 and HEVC or ColorConfig header in AV1: color_primaries transfer_characteristics matrix_coefficients They all...

These parameters are for encoder only. Yes, if not set, there are default values based on bit-ness: BT.709 for 8-bit with BT.2020 for 10-bit. For AMF decoder there are similar...
