Anton Khirnov	08bebeb1be	Revert "all: Don't set AVClass.item_name to its default value" Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit `0c6203c97a`.	10 months ago

aybe aybe	36b402f80d	avcodec/mdec: DC reading for STRv1 is like STRv2 As I understand, support for .STR files is broken for almost 10 years now (since `161442ff2c` it seems). Currently, ffmpeg fails with tons of errors like this on version 1 STRs, e.g. Wipeout 1: [mdec @ 00000000027c72c0] ac-tex damaged at 1 9 What happens is that only the audio is present in the video file. Anyway, that one character patch fixes the problem, video is now rendered.
