 Summary of the bug:
 How to reproduce:
 {{{
 % ffmpeg -y -vaapi_device /dev/dri/renderD128 -hwaccel vaapi
 -hwaccel_output_format yuv420p -i file.264 -an -vf format=nv12,hwupload
 -c:v hevc_vaapi -quality 1 -f mpegts /dev/null
 ffmpeg version N-81786-g2586668
 built on with --enable-nonfree --enable-gpl --enable-version3 --enable-
 vaapi --enable-libx264
 gcc 4.9.2 (Debian 4.9.2-10)

 Memory leakage is around 1-3 MB/s: input stream res is 720p50fps: do not
 happen with gstreamer


 Valgrind (--tool=massif)
