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.)

This also adds the capability to support alternative tags for the

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.

ff_mp4_obj_type contains the wrong type of tags for
AVOutputFormat.codec_tag. AVOutputFormat.codec_tag is used to
validate AVCodecParameters.codec_tag so needs to be the same
type of tag.

Creates new tag lists for mp4 and ismv.  New tag lists support
same list of codecs found in ff_mp4_obj_type. psp uses the same
tag list as mp4 since these both use mp4_get_codec_tag to look up tags.
