0021484d05 avformat/mpegts: update stream info when PMT ES stream_type changes
I have several .ts captures where video and audio codec changes even
though the PMT version does not change and the PIDs stay the same.
This happens during transition to/from slate (mpeg2 video and audio)
to network broadcast (hevc video and eac3 audio in private PES).

I've updated fate ts-demux expected results.

06cee0c681 doc: add swscale rewrite design document
This should hopefully serve as a better introduction to my new swscale
redesign than hunting down random commit message monologues.

6072e27e9a swscale/graph: prefer bools to ints
This is more consistent with the rest of the newly added code, which
universally switched to using bools for boolean values.

bc9696bff8 swscale/graph: make noop loop more robust
The current loop only works if the input and output have the same number
of planes. However, with the new scaling logic, we can also optimize into a
noop the case where the input has extra unneeded planes.

For the memcpy fallback to work in these cases we have to instead check if
the *output* pointer is set, rather than the input pointer.

51e912466f swscale/graph: expose ff_sws_graph_add_pass
So we can move pass-adding business logic outside of graph.c.

f297ebf97a tests/swscale: improve colorization of speedup
The old limits were a bit too tightly clustered around 1.0. Make the
value range much more generous, and also introduce a new highlight
for speedups above 10.0 (order of magnitude improvement).

eb6dc952cb avcodec/libzvbi-teletextdec: change new lines to \n in ASS header
Fixes remaining \r\n is ASS header after 57c545090d.

Fixes AVERROR_BUG error during init as this decoder expected `\r\n` in
default ASS header. strstr(..., "\r\n[Events]\r\n") failed after changes
in 57c545090d.

Fixes ticket #11545.

(This option was added in 2862b63783
when an AVCodecContext generic option was moved to
a codec private one without realizing that not every
generic one is valid for every encoder.)

45daaf2caa avcodec/mpeg12enc: Fix writing closed captions
Broken in 6e225123d8, because
ff_copy_bits() expects the amount of bits, not bytes to write.
And because it relies on the buffer to be padded, using
side_data->size * 8 is not possible. So partially revert
said commit.
