From 65d5ccb808ec93de46a2458ea8cc082ce4460f34 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Wed, 12 Jun 2024 08:37:53 +0200 Subject: [PATCH] avcodec/mpeg_er: Don't set block_index unnecessarily ff_init_block_index() sets MpegEncContext.dest and MpegEncContext.block_index. The latter is unused by ff_mpv_reconstruct_mb() (which is what this code is preparatory for) and dest is overwritten a few lines below. So don't initialize block_index at all.
