libvlc: avoid using POSIX ssize_t in libvlc · f8f228ba

Steve Lhomme authored 3 years ago

ssize_t is not a standard C type. In some cases it's supposed to hold no more
than a long [1]. That's 2 GB in normal case which is enough for 16k*16k 16-bit
RGBA.

> The implementation shall support one or more programming environments in
> which the widths of blksize_t, pid_t, size_t, ssize_t, and suseconds_t are no
> greater than the width of type long. The names of these programming
> environments can be obtained using the confstr() function or the getconf
> utility.

Changes the name of libvlc_media_new_callbacks() to
libvlc_media_new_memory() to reflect the API change. The name is similar
to libvlc_media_new_path(), libvlc_media_new_location(), libvlc_media_new_fd()
and libvlc_media_new_as_node().

In imem-access the callback cannot return more than LONG_MAX so we shouldn't
ask for more.
