Subject: vp9: Remove this_key_frame_forced setting for CBR.
X-Git-Tag: v1.8.0~738
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=aaaf9215e21d9aae155738aadeeaded3662d8b16;p=libvpx

vp9: Remove this_key_frame_forced setting for CBR.

The setting this_key_frame_forced can lead to large key frame sizes,
not suitable for CBR rate control used for RTC.
