menu "FFmpeg configuration"
comment "Licensing"
config FFMPEG_GPL
bool "Include GPL components (libpostproc, GPL filters)"
default y
help
Build libffmpeg with --enable-gpl. This adds libpostproc
and the GPL-licensed filters, and the resulting libraries are
distributed under the GPL-2.0-or-later. Kodi requires
libpostproc.
config FFMPEG_VERSION3
bool "Allow (L)GPL v3 components"
default n
help
Sets --enable-version3. Upgrades the licence of the resulting
libraries to (L)GPL-3.0-or-later. Selected automatically by the
TLS backends that require it (see below).
config FFMPEG_NONFREE
bool "Allow non-redistributable components"
default n
help
Sets --enable-nonfree. In almost all cases this prohibits
redistribution of the resulting binaries.
comment "Build properties"
config FFMPEG_X86ASM
bool "Compile x86 assembly optimizations"
depends on (x86_64 || (i386 && !(TARGET_x86_geode || TARGET_x86_legacy)))
default y
help
Not available for CPU_TYPE=pentium targets, where NASM cannot
assemble them. This option also applies to libffmpeg-mini, which
has no other options.
config FFMPEG_OPTIMIZE_SIZE
bool "Optimize for size instead of speed"
default n if x86_64
default y
help
Sets --enable-small and uses generated instead of hardcoded
tables. When disabled, decoding is faster and the libraries are
larger.
config FFMPEG_PROGRAMS
bool "Build the command line programs (ffmpeg, ffprobe)"
default y
help
When disabled only the shared libraries are built and the
ffmpeg/ffprobe packages cannot be selected.
comment "Hardware acceleration"
config FFMPEG_LIBDRM
bool "DRM support (libdrm, needed for DRM_PRIME zero-copy)"
default y
config FFMPEG_V4L2_M2M

bool "V4L2 Request API (stateless) hwaccels"

default y
help
Stateless V4L2 hardware decoding (cedrus, hantro, rkvdec, ...)
exporting DRM_PRIME frames. Requires libdrm and libudev.
# VA-API support is prepared but disabled until a libva package exists in
# the feeds; uncomment (and the DEPENDS line in the Makefile) once it does.

prompt "TLS backend"
default FFMPEG_TLS_MBEDTLS
help
mbedTLS is the default because it is the TLS library OpenWrt
itself ships by default (libustream-mbedtls, hostapd-*-mbedtls).
Selecting the backend already present in the image avoids a
second TLS library.
Licence: FFmpeg's configure requires --enable-version3 for
mbedTLS, and for OpenSSL 3.x whenever GPL components are
enabled. Together with the GPL option this makes the resulting
libraries GPL-3.0-or-later. GnuTLS carries no such requirement.
config FFMPEG_TLS_NONE
bool "none (no https/tls protocol)"

comment "External libraries"
# libdav1d support is prepared but disabled until a dav1d package exists
# in the feeds; uncomment (and the DEPENDS line in the Makefile) once it
# does. Until then AV1 is only decodable by hardware, see the help text.
#config FFMPEG_LIBDAV1D
# bool "AV1 decoding via libdav1d"
# default y
# help
# FFmpeg has no native software AV1 decoder; its built-in av1
# decoder only drives hardware acceleration (V4L2 Request API,
# VA-API). Without libdav1d, AV1 can only be decoded by hardware
# with an AV1 decoder.
config FFMPEG_LIBOPUS
bool "Opus encoding via libopus"
default y
help
Opus decoding is always available through FFmpeg's native
decoder, which is preferred even when libopus is present.
libopus adds a production-quality encoder; the native Opus
encoder is marked experimental.
config FFMPEG_LIBVORBIS
bool "Vorbis encoding via libvorbis"
default n
config FFMPEG_LIBVPX
bool "VP8/VP9 encoding via libvpx"
default n
help
VP8 and VP9 decoding is always available through FFmpeg's
native decoders, which are preferred even when libvpx is
present. libvpx therefore only adds the encoders.
config FFMPEG_LIBWEBP
bool "WebP encoding via libwebp"
default n
config FFMPEG_LIBSPEEX
bool "Speex encoding via libspeex"
default n
help
Speex decoding is always available through FFmpeg's native
decoder, which is preferred even when libspeex is present.
libspeex therefore only adds the encoder.
config FFMPEG_LIBXML2
bool "XML parsing via libxml2 (DASH/IMF demuxers)"
default n
help
The DASH and IMF demuxers are the only users of libxml2 and
are not built without it; there is no native fallback.
config FFMPEG_LAME
bool "MP3 encoding via LAME"
default y if !SOFT_FLOAT
default n
config FFMPEG_SHINE
bool "Fixed-point MP3 encoding via libshine"
default y if SOFT_FLOAT

config FFMPEG_LIBX264
bool "H.264 encoding via libx264"
depends on FFMPEG_GPL && BUILD_PATENTED
default y
config FFMPEG_FDK_AAC
bool "AAC encoding via libfdk-aac"
depends on FFMPEG_NONFREE && !FFMPEG_GPL
default n
help
The FDK licence is incompatible with the GPL, so this is only
offered for a non-GPL, nonfree build. The native FFmpeg AAC
encoder is always available.
comment "System libraries"
config FFMPEG_LIBV4L2
bool "V4L2 capture device via libv4l2 (pixel format conversion)"
default n
help
The V4L2 capture/output devices of libavdevice work without
this, using raw ioctls. libv4l2 adds the v4l-utils userspace
layer, mainly libv4lconvert for capture devices producing pixel
formats FFmpeg does not handle natively. Unrelated to hardware
decoding.
config FFMPEG_BZLIB
bool "bzip2 support"
default y
help
Only used by the Matroska demuxer for bzip2-compressed tracks.
Without it such tracks cannot be read; everything else in
Matroska is unaffected.
config FFMPEG_LZMA
bool "lzma support"
default n
help
Only used by the TIFF decoder for LZMA-compressed images.
config FFMPEG_ICONV
bool "iconv support (subtitle charset conversion)"
default y
help
Uses the iconv implementation of the C library; no additional
package is needed on musl.
comment "Components"
config FFMPEG_SELECT_COMPONENTS
bool "Manual component selection"
default n
help
Disabled: every native codec, container format, filter,
protocol and device is built, subject to the licence options
above and BUILD_PATENTED.
Enabled: the build starts from --disable-everything and only
the components selected in the options that appear below are
built; every component not selected there is absent from the
libraries. The components of the external libraries and
hardware accelerations selected above are added automatically,
as are the tls and https protocols of the selected TLS backend.
