From 33cdf51a065c568bfe3811846095f8d8ac73fe6d Mon Sep 17 00:00:00 2001 From: James Almer Date: Fri, 16 Sep 2022 11:49:17 -0300 Subject: [PATCH] avcodec/avcodec: Use the new API fields to validate the layout returned by decoders This block was scheduled for removal, which means that no validation would have taken place after the old API was removed. It was algo going to mistakenly remove an unrelated bits_per_coded_sample check.
