Iris returns an empty capture buffer (bytesused 0, no LAST flag, time 0) for every VP9 frame that isn't shown (alt-ref frames split from superframes). FFmpeg's V4L2 wrapper takes any empty capture buffer during a drain for the end of the stream, so the first hidden frame decoded after EOS ended it and the pictures still in the driver were lost (two-pass VP9 4K: 573/600 and 617/640, always the last frames); outside a drain the empty buffers were returned as pictures, which the component then guessed away by counting hidden frames. build.py now patches v4l2_context.c to requeue empty capture buffers without LAST/ERROR; the drain ends at the LAST buffer, or after a skipped empty buffer at one silent second, so it can't block. The component's hidden-frame counting is removed. Dev Frame (Batman's container): two-pass VP9 4K 600/600 and 640/640 in hardware with the same Y hashes as OMX.google.vp9.decoder (seek phase too), VP9 without hidden frames, H.264 4K and HEVC 4K 600/600, VP9 surface output 600/600. Two builds (different dirs and NDK copies) give the same libstagefrighthw.so 141de01f.
