   4 Subject: [PATCH] vp8enc: fix target bitrate config with libvpx 1.1.0
   5
   6 libvpx 1.1.0 disallows a bitrate of 0, which was used by
   7 vp8enc as a default value.
   8
   9 Instead, we use the default libvpx bitrate, scaled to our
  10 video size, if no bitrate was specified.
  11
  12 This fixes encoding VP8 video with libvpx 1.1.0.
