From 963bdac226b611664bdd033a8b3a914e5e148ebd Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sat, 8 Jun 2024 01:28:16 +0200 Subject: [PATCH] avcodec/vc1_block: Simplify resetting coded_block Everything that init_block_index() sets will be overwritten a few lines below again, so don't call it and simply calculate the only thing that is used (namely block_index[0]) manually.
