  "message": "Release previous hash-me memory when encoding new frame\n\nThe hash-table from hash-me has two usages:\n  - intrablock copy for keyframe\n  - prune subpel search in interframe\n\nThe current usages only require the hash-table for the current and\nprevious coded frame be kept. But currently in the codebase, the\nmemory is only released when the frame buffers are refreshed.\n\nThis commit changes so that the hash-tables for frames other than\nthe current and previously coded frames are released, which allows\nsignificant memory saving.\n\nPerformance when encoding 4k videos over 33 frames:\nBaseline: 7.2 GB\n Commit : 3.1 GB\n Saving : 4.1 GB, or ~57% memory reduction\n\nBUG\u003daomedia:2453\n\nChange-Id: I659dbe5eb2d7badea7239a841fc5ba06987f75f7\n",
