When 'out' is an AVFrame that does not have buffers preallocated,
swr_convert_frame tries to allocate buffers of the right size. However
in calculating this size it failed to check for whether 'in' is NULL
(requesting that swr's internal buffers are to be flushed).

libvorbis comes with pkg-config files since at least v1.0.1, way back in 2003.

We need the two checks for vorbis and vorbisenc because we use functions from
both and Xiph considers them separate libraries.

The check is inverted (vorbis first then vorbisenc) because add_extralibs()
prepends to EXTRALIBS instead of appending. For both shared and static linking
the order didn't seem to matter anyway, testing with MinGW.

Some .srt files use this tag.

(An alternative implementation would be correctly ignoring unknown tags,
and treating them as whitespace. libass can do automatic line wrapping.)

mux.c init_muxer() already sets codec_tag correctly in the cases

This also adds the capability to support alternative tags for the
same codec_id.

This reverts commit 24bb7db4.

noise has to after all be sign extended, not zero extended, on tests
other than checkasm.
Fixes most aac tests broken by the now reverted commit.

when use fmp4 segment type in hls and use codec copy,
there have an error message.
error message:
   [mp4 @ 0x25df020] Tag avc1 incompatible with output codec id '28' ([33][0][0][0])
   [hls @ 0x2615c80] Some of the provided format options in '(null)' are not recognized
   Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
this patch can fix it.
