b0c1f248d9 avcodec/svq1enc: output ident string in extradata field
This will enable the acurate identification of FFmpeg produced

700a39e63c avcodec/mpegvideodata: Mark tables as hidden
This e.g. allows compilers to bake the offset implied
by using ff_mpeg12_dc_scale_table[3] (as the SpeedHQ encoder
does) into the general offset; for certain arches this is
also necessary in order to avoid building suboptimal code.

01b9abd771 avfilter/vf_frei0r: set align to 1 for frei0r frames
The frei0r API requires linesize to be width * 4.
Since the align property of ff_default_get_video_buffer2
specifies line alignment, not buffer alignment, the
previous value of 16 breaks this requirement for frames
whose width is a multiple of 8, but not a multiple of 16
as it adds extra padding to ensure line aligment.

7e93fba51f avcodec/mpegvideo: Remove always-false check
This basically reverts cc0380222a.
At the time of said commit, cleanup on init failure was very
buggy. For codecs with the INIT_CLEANUP cap, the close function
could be called on error even before the private data has been
allocated; and when using frame threading the same could also
happen even without said flag. Some mpegvideo decoders were
affected by the latter.

Yet both of these issues have been fixed long ago, the latter
in commit e9b6617579. Therefore
the workaround in ff_mpv_common_end() can be removed.

f8efd890bf avutil/tx_template: Move function pointers to const memory
This can be achieved by moving the AVOnce out of the structure
containing the function pointers; the latter can then be made
const.
This also has the advantage of eliminating padding in the structure
(sizeof(AVOnce) is four here) and allowing the AVOnces to be put
into .bss (dependening upon the implementation).

cb803a0072 swscale: aarch64: Fix yuv2rgb with negative strides
Treat the 32 bit stride registers as signed.

Alternatively, we could make the stride arguments ptrdiff_t instead
of int, and changing all of the assembly to operate on these
registers with their full 64 bit width, but that's a much larger
and more intrusive change (and risks missing some operation, which
would clamp the intermediates to 32 bit still).

ff_rl_mpeg1 and ff_rl_mpeg2 differ only in RLTable.table_vlc,
which ff_rl_init() does not use to initialize RLTable.max_level,
RLTable.max_run and RLTable.index_run. This implies
that these tables agree for ff_rl_mpeg1 and ff_rl_mpeg2;
hence one can just use one of them and avoid calling ff_rl_init()
ff_rl_mpeg2 alltogether.
