The branch main has been updated by ehaupt: URL: https://cgit.FreeBSD.org/ports/commit/?id=4aca6786ed5623cb888e14a2f35d0542952dec0e commit 4aca6786ed5623cb888e14a2f35d0542952dec0e Author: Emanuel Haupt <ehaupt@FreeBSD.org> AuthorDate: 2023-06-09 06:53:07 +0000 Commit: Emanuel Haupt <ehaupt@FreeBSD.org> CommitDate: 2023-06-09 06:53:07 +0000 audio/audiowmark: Add new port A sound file is read by the software, and a 128-bit message is stored in a watermark in the output sound file. For human listeners, the files typically sound the same. However, the 128-bit message can be retrieved from the output sound file. Our tests show, that even if the file is converted to mp3 or ogg (with bitrate 128 kbit/s or higher), the watermark usually can be retrieved without problems. The process of retrieving the message does not need the original audio file (blind decoding). Internally, audiowmark is using the patchwork algorithm to hide the data in the spectrum of the audio file. The signal is split into 1024 sample frames. For each frame, some pseoudo-randomly selected amplitudes of the frequency bands of a 1024-value FFTs are increased or decreased slightly, which can be detected later. --- audio/Makefile | 1 + audio/audiowmark/Makefile | 51 ++++++++++++++++++++++++++++++++++++++++++++++ audio/audiowmark/distinfo | 3 +++ audio/audiowmark/pkg-descr | 15 ++++++++++++++ 4 files changed, 70 insertions(+) diff --git a/audio/Makefile b/audio/Makefile index feedad6b392f..eaa5894d5f7f 100644 --- a/audio/Makefile +++ b/audio/Makefile @@ -43,6 +43,7 @@ SUBDIR += audacity SUBDIR += audiere SUBDIR += audiocd-kio + SUBDIR += audiowmark SUBDIR += aumix SUBDIR += autocd SUBDIR += autotalent diff --git a/audio/audiowmark/Makefile b/audio/audiowmark/Makefile new file mode 100644 index 000000000000..41a233b17440 --- /dev/null +++ b/audio/audiowmark/Makefile @@ -0,0 +1,51 @@ +PORTNAME= audiowmark +PORTVERSION= 0.6.1 +CATEGORIES= audio + +MAINTAINER= ehaupt@FreeBSD.org +COMMENT= Audio and video watermarking tool +WWW= https://github.com/swesterfeld/audiowmark + +LICENSE= GPLv3 +LICENSE_FILE= ${WRKSRC}/COPYING + +BUILD_DEPENDS= ${LOCALBASE}/include/fftw3.h:math/fftw3 \ + autoconf-archive>=0:devel/autoconf-archive +LIB_DEPENDS= libfftw3f.so:math/fftw3-float \ + libgcrypt.so:security/libgcrypt \ + libgpg-error.so:security/libgpg-error \ + libmpg123.so:audio/mpg123 \ + libsndfile.so:audio/libsndfile \ + libzita-resampler.so:audio/zita-resampler + +USES= autoreconf localbase:ldflags pkgconfig shebangfix +USE_GITHUB= yes +GH_ACCOUNT= swesterfeld + +SHEBANG_FILES= src/videowmark + +GNU_CONFIGURE= yes + +PLIST_FILES= bin/audiowmark \ + bin/videowmark +PORTDOCS= README.adoc + +OPTIONS_DEFINE= DOCS FFMPEG +OPTIONS_DEFAULT= FFMPEG + +FFMPEG_LIB_DEPENDS= libavcodec.so:multimedia/ffmpeg +FFMPEG_CONFIGURE_ON= --with-ffmpeg + +.include <bsd.port.pre.mk> + +# Fails to compile with llvm15 +# https://github.com/swesterfeld/audiowmark/issues/36 +.if ${OSVERSION} >= 1400000 +USE_GCC= yes +.endif + +post-install: + ${MKDIR} ${STAGEDIR}${DOCSDIR} + ${INSTALL_DATA} ${WRKSRC}/README.adoc ${STAGEDIR}${DOCSDIR} + +.include <bsd.port.post.mk> diff --git a/audio/audiowmark/distinfo b/audio/audiowmark/distinfo new file mode 100644 index 000000000000..b60df4e2bd33 --- /dev/null +++ b/audio/audiowmark/distinfo @@ -0,0 +1,3 @@ +TIMESTAMP = 1686217029 +SHA256 (swesterfeld-audiowmark-0.6.1_GH0.tar.gz) = 033500755f333db228c0192c80782fa4ad947e7604a5f34689a3ce4eef72afcc +SIZE (swesterfeld-audiowmark-0.6.1_GH0.tar.gz) = 102875 diff --git a/audio/audiowmark/pkg-descr b/audio/audiowmark/pkg-descr new file mode 100644 index 000000000000..a5db5a3d8509 --- /dev/null +++ b/audio/audiowmark/pkg-descr @@ -0,0 +1,15 @@ +A sound file is read by the software, and a 128-bit message is stored in +a watermark in the output sound file.
