Buffers are allocated inside some metadata types, so we must ensure
that the object is visible to the free function before a parse failure.

Found by libFuzzer.

Also return an better error code if it is set numerically.
(This option was added in 2862b63
when an AVCodecContext generic option was moved to
a codec private one without realizing that not every
generic one is valid for every encoder.)

Fixes remaining \r\n is ASS header after 57c5450.

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 57c5450.

Fixes ticket #11545.

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).

So we can move pass-adding business logic outside of graph.c.

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.

I need to reuse these inside `ops.c`.

This is more consistent with the rest of the newly added code, which
universally switched to using bools for boolean values.

This should hopefully serve as a better introduction to my new swscale
redesign than hunting down random commit message monologues.

Avoids writing an empty json blob in setup error cases.

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.

The code to initialize the ungrouped bap mantissa tables
(bap 3 or 5) takes more bytes of .text than the tables itself;
they have therefore been hardcoded.

For GCC (14, -O3, albeit in an av_cold function), the initialization
code takes 99B each for the fixed and floating point decoders
(the code is currently duplicated), whereas the hardcoded tables
only take 96B. For Clang 19 it were 374B each (I don't now what
Clang was doing there).

0. Version 1.
1. The WHIP muxer has been renamed and refined, with improved logging context and error messages for SSL, DTLS, and RTC.
2. Magic numbers have been replaced with macros and extracted to functions, and log levels have been altered for better clarity.
3. DTLS curve list has been updated, and SRTP profile names have been refined for FFmpeg and OpenSSL.
4. ICE STUN magic number has been refined, and RTP payload types have been updated based on Chrome's definition.
5. Fixed frame size has been refined to rtc->audio_par->frame_size, and h264_mp4toannexb is now used to convert MP4/ISOM to annexb.
6. OPUS timestamp issue has been addressed, and marker setting has been corrected after utilizing BSF.
7. DTLS handshake and ICE handling have been optimized for improved performance, with a single handshake timeout and server role to prevent ARQ.
8. DTLS BIO callback has been implemented for packet fragmentation, and MTU settings have been refined using SSL_set_mtu and DTLS_set_link_mtu.
9. Consolidated ICE request/response handling and DTLS handshake into a single function, and fixed OpenSSL build errors to work with Pion.

Abstract dtls as ffmpeg protocol

Since i make the dtls as a ffmpeg protocol, we need init it use ffurl_oepn after ICE binding. But before that, SDP need the fingerprint of cert
So i implement these gen or read in separated function and can be called by whip because we need obtain fingerprint for sdp exchange.
So we need pass the string of key and cert into dtls from whip.

debug: set info callback for tls_openssl

dtls: refactor the logic of bio

make the dtls use custom bio rather than callback to match the tls implementation

dtls: add option that re-use udp from demuxer/muxer

integrate print_ssl_error, read, write as same as implementation in tls

remove openssl_dtls_state_trace, opessl_ssl_get_error.

implemente dtls_handshake function.

pass patchcheck

fix tailing whitespace, missing av_cold, x==0 can be simplified, forget use av_log, use snprintf instead of sprintf, add braces for if else (Don’t wrap single-line blocks in braces. Use braces only if there is an accompanying else statement.)

improve the api name like url_read_all -> ff_url_read_all.

fix av_log in tls_openssl.

use thread-safe function openssl_get_error instead of ERR_error_string(ERR_get_error(), NULL) in part of tls_openssl. In other case, use the ERR_error_string(ERR_get_error(), NULL) when there is no TLSContext.

This patch make the whip muxer depends dtls protocol,
and dtls protocol depends openssl for now.
