X-Git-Tag: v1.8.0~362^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6367818c500291bcde56cd126dace3b825be924a;p=libvpx

Increase encoder buffer for multi-layer ARFs

When multi-layer ARF mode is enabled, increase the encoder buffer
to account for the situation where several ARFs are coded together
in a frame packet.
