This is unnecessary, as ff_flac_set_channel_layout can handle any number of channels.

Accidentally prefixed ff_ with cextern.

Non-ascii chars are not correctly rendered in both MAN and HTML output or
may even cause compilation failure. Thus avoid to use them until we find
a satisfying way to deal with them.

The DTS needs to be resynched against the segment start PTS, or the

Check slice count and input buffer size before constructing a possibly
invalid pointer, not after.

pp_time is never set for h264

They serve no useful purpose and wreak all kind of havoc when h264.h is
included elsewhere.

They were added to the latest FLAC specification:

The luma init is left at 0x80 as it was previously, and tested and
working since a long time. Its also mandated to be 0x80 by at least
one specification. Cases that need different values already had
code in place to handle them.
