d05f6aac2d Codecs: mp4: Skip FOURCC filetype chunk check
Instead of FOURCC it needs ignore-case text match. Also value can contain \0 ('m4a\0' instead of expected 'm4a ').But let's simply skip it and let decoder handle it.

e3e72d6dba metadata/mp4.c fix small oversight / bug
didn't set the genre string to null on case entry
means read failure would leave genre string indeterminate

add explicit NULL & leave genre uninitialized

bdc3dd4fca MP4: append mdat sections together in metadata parser
mp4 files can have multiple 'mdat' chunks.  This is common for
audiobooks, where there is often a secondary mdat containing the
chapter names, but it's also legal to have multiple mdat chunks
for a single logical "track"

This confuses the mp4 metadata parser, which assumes there is
only a single mdat, and always uses the last mdat seen to
determine the "filesize" of the data we're trying to decode.

Work around this by appending each mdat's size to result in the final
"filesize"

cadb3627fc Add rbcodecplatform.h and rbcodecconfig.h.
librbcodec users must provide these two files when the library is built.
rbcodecconfig.h provides configuration #defines and basic types, and
will be included by public librbcodec headers, so it must not conflict
with the user's code. rbcodecplatform.h provides various OS functions,
and will only be included by source files and private headers. This
system is intended to provide maximum flexibility for use on embedded
systems, where no operating system headers are included. Unix systems
can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with
minimal changes.
