From 5e546864b09379910721b35a14713982d933d9dd Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 6 Oct 2019 07:01:13 +0200 Subject: [PATCH] avcodec/flac_parser: Use native endianness when possible FLAC sync codes contain a byte equal to 0xFF and so the function that searches for sync codes first searched for this byte. It did this by checking four bytes at once; these bytes have been read via AV_RB32, but the test works just as well with native endianness.
