Applied as 912ac82a3c769792ad992534f3df9b0a549ff827 to make this set under review shorter, with a minor improvement to the commit message ("base *pcmC* endianness on just the LSB") Jan

From: Jan Ekström <jeebjp@gmail.com> 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(-)
