RX 5700 support b-frames?

Open stasko48 opened this issue 4 years ago • 5 comments

Using driver version 20.12.1. On the H264 encoder, although I cannot set any bitrate other than 0 or 1. There is an option for setting b frames in master view, which wasn't present on previous drivers other than 20.11.2. I tried recording a file, using CQP setting the B-Frame Period to 1. However, using avidemux, it does not show any b frames. Is it a bug?

amf does not support b-frames. not for avc, not for hevc and doesn't matter what gpu you use.

i always thought R9 380 and 380X and 385 support b-frames for AMD AMF VCE

B-Frame support has been added a couple months ago, now OBS needs to support it. Source: https://www.tomshardware.com/news/amd-amf-encoder-quality-boost

https://github.com/obsproject/obs-studio/pull/6508 As you can see, a new amf plugin for obs is being worked on. But B-frames is only for Rdna2 gpus (6000series)
