Subject: vp8-mfqe: Increase initial frame# threshold
X-Git-Tag: v1.8.0~71
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=18d260d13f2be7ff1c5bc7b75edc3ab2b917cf83;p=libvpx

vp8-mfqe: Increase initial frame# threshold

Increase the initial frame number threshold
for the mfqe, as using the running average of
last_base_qindex doesn't work well after very
first frame.

Only affects the very first few frames.
Fixes an issue with a test.
