avformat/mp3dec: replace SAME_HEADER_MASK with MP3_MASK · 72915ca8

Limin Wang authored Nov 11, 2019

mp3 header bitstream syntax:
header()
{
    syncword   12bits bslsf
    id         1bit    bslsf
    layer      2bit    bslsf
    protection_bit 1bit bslsf
    bitrate_index 4bits bslsf
    sampling_frequency 2bits bslsf
    padding_bit  1bit bslsf
    private_bit 1bit bslsf
    mode 2bits bslsf
    mode_extension 2bits bslsf
    copyright 1bit bslsf
    original/home 1bit bslsf
    emphasis 2bits bslsf
}

if the header is masking with MP3_MASK(0xFFFE0CCF), below fields will be cleared:
protection_bit, bitrate_index, sampling_freqency, mode

with SAME_HEADER_MASK(0xFFFE0C00), extra below fields will be cleared which didn't make
sense:
mode_extension, copyright, original/home, emphasis

As the MP3_MASK is good for same mp3 header masking and is defined in the
header, so it's preferable to remove SAME_HEADER_MASK to keep the masking same.

avcodec/dvdec: Don't use restrict directly to fix build on MSVC · b25b6432

Andreas Rheinhardt authored Nov 10, 2019

004ebd4b added a function with a parameter that was declared as restrict
and not av_restrict. This is not supported by MSVC as several FATE-boxes
that now fail to build show. So use av_restrict.
