The issue still exists for both gdigrab and ddagrab.

ddagrab stops with an error.

[out#0/mp4 @ 000001d3c564ad00] Codec AVOption b:a (set bitrate (in
bits/s)) has not been used for any stream. The most likely reason is
either wrong type (e.g. a video option with no video streams) or that it
is a private option of some decoder which was not actually used for any
stream.
Stream mapping:
format:default -> Stream #0:0 (libx264)
