We are using Amazon AWS g4ad instance which has this card in it. We are building a simple encoding app with AMF and its H264. However we see some issues:
1. B-frames: Although the SDK is not reporting any error when we enable b-frames and the value we set is accepted with AMF_OK the output has no b-frames. At the same time capability manager reports b-frames are not supported. Is it really such high end card not supporting b-frames or there is some other issue?
2. Reference frames: The SDK and the capability manager reports that reference frames are supported. Supported values are between 1 and 16. However no matter what we set the output refs are always set to 1 ( confirmed with Media Info ). The same code works on other low end Radeon card.
The above results has been confirmed with third party source code base using AMF like ffmpeg.
