From 912ac82a3c769792ad992534f3df9b0a549ff827 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan=20Ekstr=C3=B6m?= Date: Sat, 4 Feb 2023 21:26:01 +0200 Subject: [PATCH] avformat/mov: base pcmC endianness on just the LSB As per 23003-5:2020, the rest of the bits are reserved, and thus in the future they may be utilized for something else. Quote: format_flags is a field of flags that modify the default PCM sample format. Undefined flags are reserved and shall be zero. The following flag is defined: 0x01 indicates little-endian format. If not present, big-endian format is used. --- libavformat/mov.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavformat/mov.c b/libavformat/mov.c index cdd44a9e44..a9911c0f79 100644 --- a/libavformat/mov.c +++ b/libavformat/mov.c @@ -1608,7 +1608,7 @@ static int mov_read_pcmc(MOVContext *c, AVIOContext *pb, MOVAtom atom) } format_flags = avio_r8(pb); - if (format_flags == 1) // indicates little-endian format.
