Subject: [PATCH] lavc/libopenh264: Drop openh264 runtime version checks
Years ago, openh264 releases often changed their ABI without changing
the library soname. To avoid running into ABI issues, a version check
was added to lavc libopenh264 code to error out at runtime in case the
build time and runtime openh264 versions don't match.
This should no longer be an issue with newer openh264 releases and we
can drop the runtime version check and rely on upstream doing the right
thing and bump the library soname if the ABI changes, similar to how
other libraries are consumed in ffmpeg.
Almost all major distributions now include openh264 and this means there
are more eyes on ABI changes and issues are discovered and reported
quickly. See e.g. https://github.com/cisco/openh264/issues/3564 where an
ABI issue was quickly discovered and fixed.
Relaxing the check allows downstream distributions to build ffmpeg
against e.g. openh264 2.3.1 and ship an update to ABI-compatible
openh264 2.4.0, without needing to coordinate a lock step update between
ffmpeg and openh264 (which can be difficult if openh264 is distributed
by Cisco and ffmpeg comes from the distro, such as is the case for
Fedora).

+@section libsvt_hevc
+
+Scalable Video Technology for HEVC (SVT-HEVC) encoder wrapper.
+
+This encoder requires the presence of the headers and
+library during configuration. You need to explicitly configure the
+build with @code{--enable-libsvthevc}. The library is detected using
+@command{pkg-config}.
+
+For more information about the library see
+@url{https://github.com/intel/SVT-HEVC.git}.
+
+@subsection Options
+
+The following FFmpeg global options affect the configurations of the
+libsvt_hevc encoder:
+
+@table @option
+@item b (@emph{bitrate})
+Set the bitrate (as a number of bits per second). Default is 7M.
+
+@item g / @option{gop_size}
+Set the GOP size. Default is -2 (unspecified).
+
+@item flags +cgop
+Enable closed GOP.
+
+@item qmin (@emph{min-q})
+Default is 10
+
+@item qmax (@emph{max-q})
+Default is 48
+
+Set minimum/maximum quantisation values. Valid range is from 0 to 51
+(Only used when bit rate control mode @option{rc} is set to 1(vbr) mode.
+It is required that qmax >= qmin).
+
+@item profile (@emph{profile})
+Set profile restrictions. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main profile
+@item main10
+main10 profile
+@item rext
+rext profile
+@end table
+
+Default is 1 (main).
+
+@item level (@emph{level})
+
+@option{level} sets the value of @emph{level}.
+Set level (level_idc). Default is 0 (to be determined by the encoder).
+
+@end table
+
+The encoder also has its own specific options:
+
+@table @option
+@item aud (@emph{aud})
+Enable use of access unit delimiters when set to 1. Default is 0 (Off).
+
+@item hielevel
+Set hierarchical levels. Can assume one of the following possible values:
+
+@table @samp
+@item flat
+flat more
+@item 1 level
+Minigop size is 2^1
+@item 2 level
+Minigop size is 2^2
+@item 3 level
+Minigop size is 2^3
+@end table
+
+Default is 3 level.
+
+@item la_depth
+Set look-ahead depth, depending on @option{rc}: for @var{vbr}, it's recommended
+to unset it and use the default value (the intra period); for @var{cqp}, better
+specify the look-ahead depth.
+
+The range is @var{-1-256}. Default is -1 (unset and the default value to be used).
+
+@item preset
+Set the quality vs density tradeoff point at which the encoding is to be performed.
+Higher perset value, higher density and lower quality.
+
+The range is @var{0-12}. Default is 9.
+
+@item tier
+Set @emph{general_tier_flag}. This may affect the level chosen for the stream
+if it is not explicitly specified. Can assume one of the following possible values:
+
+@item socket
+Target CPU socket to use. 0 or 1 are supported. -1 use all available (default)
+
+@table @samp
+@item main
+main tier
+@item high
+high tier
+@end table
+
+Default is 1 (main).
+
+@item rc
+Set bit rate control mode. Can assume one of the following possible values:
+
+@table @samp
+@item cqp
+Constant QP (CQP) mode
+@item vbr
+Variable Bit Rate (VBR) mode
+@end table
+
+Default is 0 (cqp).
+
+@item forced_idr
+Force keyframes to be IDR if set to >=0 (the value sets headers insertion interval). Default is -1 (CRA).
+
+@item asm_type
+Auto select highest supported asm if set to 1 or C only if 0. Default is 1.
+
+@item qp
+Initial quantization parameter for the intra pictures used when
+@option{rc} is cqp mode. The range is from @var{0-51}. Default is 32.
+
+@item sc_detection
+Enables or disables the scene change detection algorithm. Default is 0 (disabled).
+
+@item tune
+Set quality tuning mode. Can assume one of the following possible values:
+
+@table @samp
+@item sq
+Visually optimized mode
+@item oq
+PSNR / SSIM optimized mode
+@item vmaf
+VMAF optimized mode
+@end table
+
+Default is 1 (oq).
+
+@item bl_mode
+Enables or disables Random Access Prediction. Default is 0 (disabled).

Edit the default codec selection such that
ffmpeg -i youtube.blah.webm foobar.mkv
without any further arguments can produce a result even on a
reduced codec selection list.

We can't directly depend on OpenH264, but we can weakly link to it
and gracefully expose the capability.

From a641e629591d68bd3edd99bddec623dc31295f6b Mon Sep 17 00:00:00 2001
From: Kalev Lember <klember@redhat.com>
Date: Wed, 6 Dec 2023 14:37:34 +0100
Subject: [PATCH] lavc/libopenh264: Drop openh264 runtime version checks
Years ago, openh264 releases often changed their ABI without changing
the library soname. To avoid running into ABI issues, a version check
was added to lavc libopenh264 code to error out at runtime in case the
build time and runtime openh264 versions don't match.
This should no longer be an issue with newer openh264 releases and we
can drop the runtime version check and rely on upstream doing the right
thing and bump the library soname if the ABI changes, similar to how
other libraries are consumed in ffmpeg.
Almost all major distributions now include openh264 and this means there
are more eyes on ABI changes and issues are discovered and reported
quickly. See e.g. https://github.com/cisco/openh264/issues/3564 where an
ABI issue was quickly discovered and fixed.
Relaxing the check allows downstream distributions to build ffmpeg
against e.g. openh264 2.3.1 and ship an update to ABI-compatible
openh264 2.4.0, without needing to coordinate a lock step update between
ffmpeg and openh264 (which can be difficult if openh264 is distributed
by Cisco and ffmpeg comes from the distro, such as is the case for
Fedora).

+@section libsvt_hevc
+
+Scalable Video Technology for HEVC (SVT-HEVC) encoder wrapper.
+
+This encoder requires the presence of the headers and
+library during configuration. You need to explicitly configure the
+build with @code{--enable-libsvthevc}. The library is detected using
+@command{pkg-config}.
+
+For more information about the library see
+@url{https://github.com/intel/SVT-HEVC.git}.
+
+@subsection Options
+
+The following FFmpeg global options affect the configurations of the
+libsvt_hevc encoder:
+
+@table @option
+@item b (@emph{bitrate})
+Set the bitrate (as a number of bits per second). Default is 7M.
+
+@item g / @option{gop_size}
+Set the GOP size. Default is -2 (unspecified).
+
+@item flags +cgop
+Enable closed GOP.
+
+@item qmin (@emph{min-q})
+Default is 10
+
+@item qmax (@emph{max-q})
+Default is 48
+
+Set minimum/maximum quantisation values. Valid range is from 0 to 51
+(Only used when bit rate control mode @option{rc} is set to 1(vbr) mode.
+It is required that qmax >= qmin).
+
+@item profile (@emph{profile})
+Set profile restrictions. Can assume one of the following possible values:
+
+@table @samp
+@item main
+main profile
+@item main10
+main10 profile
+@item rext
+rext profile
+@end table
+
+Default is 1 (main).
+
+@item level (@emph{level})
+
+@option{level} sets the value of @emph{level}.
+Set level (level_idc). Default is 0 (to be determined by the encoder).
+
+@end table
+
+The encoder also has its own specific options:
+
+@table @option
+@item aud (@emph{aud})
+Enable use of access unit delimiters when set to 1. Default is 0 (Off).
+
+@item hielevel
+Set hierarchical levels. Can assume one of the following possible values:
+
+@table @samp
+@item flat
+flat more
+@item 1 level
+Minigop size is 2^1
+@item 2 level
+Minigop size is 2^2
+@item 3 level
+Minigop size is 2^3
+@end table
+
+Default is 3 level.
+
+@item la_depth
+Set look-ahead depth, depending on @option{rc}: for @var{vbr}, it's recommended
+to unset it and use the default value (the intra period); for @var{cqp}, better
+specify the look-ahead depth.
+
+The range is @var{-1-256}. Default is -1 (unset and the default value to be used).
+
+@item preset
+Set the quality vs density tradeoff point at which the encoding is to be performed.
+Higher perset value, higher density and lower quality.
+
+The range is @var{0-12}. Default is 9.
+
+@item tier
+Set @emph{general_tier_flag}. This may affect the level chosen for the stream
+if it is not explicitly specified. Can assume one of the following possible values:
+
+@item socket
+Target CPU socket to use. 0 or 1 are supported. -1 use all available (default)
+
+@table @samp
+@item main
+main tier
+@item high
+high tier
+@end table
+
+Default is 1 (main).
+
+@item rc
+Set bit rate control mode. Can assume one of the following possible values:
+
+@table @samp
+@item cqp
+Constant QP (CQP) mode
+@item vbr
+Variable Bit Rate (VBR) mode
+@end table
+
+Default is 0 (cqp).
+
+@item forced_idr
+Force keyframes to be IDR if set to >=0 (the value sets headers insertion interval). Default is -1 (CRA).
+
+@item asm_type
+Auto select highest supported asm if set to 1 or C only if 0. Default is 1.
+
+@item qp
+Initial quantization parameter for the intra pictures used when
+@option{rc} is cqp mode. The range is from @var{0-51}. Default is 32.
+
+@item sc_detection
+Enables or disables the scene change detection algorithm. Default is 0 (disabled).
+
+@item tune
+Set quality tuning mode. Can assume one of the following possible values:
+
+@table @samp
+@item sq
+Visually optimized mode
+@item oq
+PSNR / SSIM optimized mode
+@item vmaf
+VMAF optimized mode
+@end table
+
+Default is 1 (oq).
+
+@item bl_mode
+Enables or disables Random Access Prediction. Default is 0 (disabled).
+@end table

From 42982b5a5d461530a792e69b3e8abdd9d6d67052 Mon Sep 17 00:00:00 2001

Subject: [PATCH] avformat/ffrtmpcrypt: Fix int-conversion warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-type: text/plain
The gcrypt definition of `bn_new` used to use the return statement
on errors, with an AVERROR return value, regardless of the signature
of the function where the macro is used - it is called in
`dh_generate_key` and `ff_dh_init` which return pointers. As a result,
compiling with gcrypt and the ffrtmpcrypt protocol resulted in an
int-conversion warning. GCC 14 may upgrade these to errors [1].
This patch fixes the problem by changing the macro to remove `AVERROR`
and instead set `bn` to null if the allocation fails. This is the
behaviour of all the other `bn_new` implementations and so the result is
already checked at all the callsites. AFAICT, this should be the only
change needed to get ffmpeg off Fedora's naughty list of projects with
warnings which may be upgraded to errors in GCC 14 [2].
