651c79da36 fftools/ffmpeg_filter: check that filter type matches output stream type
For simple filtergraphs. For complex filtergraphs they always match.

8e35e33d42 fftools/ffmpeg_filter: stop accessing AVCodecContext.codec
Instead pass the encoder through a newly-added output options struct,
analogous to previously added input options.

Will allow decoupling filtering from encoding in future commits.

a9709b3c83 avcodec/mpegvideo_dec, mpeg12dec: Move MPEG1/2 code to mpeg12dec.c
Up until now, ff_mpv_frame_start() offsets the data of the current
picture and doubles the linesizes of all pictures if the current
picture is field-based so that data and linesize allow to address
the current field only.

This is done based upon the current picture_structure value.
Only two mpegvideo-based decoders ever set this field: mpeg1/2
and VC-1; but the latter only does it after ff_mpv_frame_start()
(when using hardware-acceleration and in order to signal it to
the DXVA2 hwaccel) in which case no offset is applied in
ff_mpv_frame_start(). So only one decoder actually wants this
offset*; therefore move the code performing it to mpeg12dec.c.

*: VC-1 doubles linesize when using field_mode (not only the picture's
linesize, but also uvlinesize and linesize), yet it does not offset
anything. This is further proof that this should not be performed
generically.

Also move MPEG-1/2 specific setting of the top-field-first flag.
(The change here implies that the AVFrame in current_picture
may have different top-field-first flags than the AVFrame
from current_picture_ptr, but this doesn't matter as only
the latter's are used.)

2d79ae3f8a lavc/vvc: Error if SPS ID is duplicated within CVS
Key line from the spec is:

"All SPS NAL units with a particular value of sps_seq_parameter_set_id
in a CVS shall have the same content."

Prior to this patch, the VVC decoder's behaviour on encountering a
duplicated SPS ID (within the entire bitstream, not restricted to
a CVS) was simply to replace the entry in the SPS lookup table with the
new data.  Illegal bitstreams with multiple SPSs in the same CVS sharing
an ID but differing elsewhere could cause all manner of issues.

The patch tracks which SPS IDs have been used in the given CVS using the
new sps_id_used field of VVCParamSets.  If it encounters an SPS with an
ID already in use and whose content differs from the previous SPS, it
throws an AVERROR_INVALIDDATA.

0fc975c0d3 avcodec/ass,webvttdec: implement more portable curly brace escapes
Unlike what the old comment suggested, standard ASS has no character
escape mechanism, but a closing curly bracket doesn't even need one.

For manual authored sub files using a full-width variant of an
appropriate font and with scaling and spacing modifiers is a common
workaround.
This is not an option here, but we can still make things much less bad.
Now the desired opening bracket still shows up in libass, and
standard renders will merely display a backslash in its place
instead of stripping the following text like before.
