It's suggested to renable OUT_ALLOC by reverting PR #494 , some encoding would hang such as:

./SvtHevcEncApp -i bbb_1920x1080_420p.yuv -w 1920 -h 1080 -n 5000 -hierarchical-levels 0

Because randomly POC 278 (279 or 280) could be posted from EntropyCoding kernel, but they couldn't go through (single thread) Packetization which already hangs to dequeue the object from Output FIFO when handling latter pictures (such as POC 405) which may enter Packetization ahead of POC 278.

So the issue can be also worked around by PR #512 .
