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.)
Added 2 byte skipping if there no sound present, that fixes playback
files without sound stream.

If AVCodecParameters.codec_tag is 'hvc1' use it instead of 'hev1' for
h.265 streams. QuickTime (and other Apple software) requires 'hvc1'.

mux.c init_muxer() already sets codec_tag correctly in the cases
simplified here.
This also adds the capability to support alternative tags for the

This reverts commit 24bb7db403.
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

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.

The scale2ref filter will now maintain the DAR of the main input and
not the DAR of the reference input. This previous behavior was deemed
counterintuitive for most (all?) use-cases.
Before:
scale2ref=iw/4:ow/mdar
in w:320 h:240 fmt:rgb24 sar:1/1
ref w:640 h:360 fmt:rgb24 sar:1/1
out w:160 h:120 fmt:rgb24 sar:4/3 flags:0x2
SAR: ((120 * 640) / (160 * 360)) * (1 / 1) = 4 / 3
DAR: (160 / 120) * (4 / 3) = 16 / 9
(main out now same DAR as ref)
Now:
scale2ref=iw/4:ow/mdar
in w:320 h:240 fmt:rgb24 sar:1/1
ref w:640 h:360 fmt:rgb24 sar:1/1
out w:160 h:120 fmt:rgb24 sar:1/1 flags:0x2
SAR: ((120 * 320) / (160 * 240)) * (1 / 1) = 1 / 1
DAR: (160 / 120) * (1 / 1) = 4 / 3
(main out same DAR as main in)
The scale2ref FATE test has also been updated.
