Hi, The attached patch fixes playback of MP4/VP9 media containing superframes when using the built-in VP9 decoder.
As an example, https://github.com/Netflix/vp9-dash/raw/master/DASH-Samples/Fountain_2997_0560kbps_640x480_4x3PAR.ivf_DashUnencrypted.ismv plays with corrupted frames using ffplay without this patch and works fine with the patch applied (or with libvpx built with --enable-vp9-highbitdepth forced via -vcodec libvpx). Cheers,

MP4 media containing VP9 using superframes (such as https://github.com/Netflix/vp9-dash/raw/master/DASH-Samples/Fountain_2997_0560kbps_640x480_4x3PAR.ivf_DashUnencrypted.ismv) does not decode correctly with the built-in VP9 decoder because superframes are passed to the decoder whole rather than split into individual frames.
