Installation of Transcode

[Note]

Note

The details of how the FFmpeg libraries are used has changed since this version of Transcode was released. The patch allows the package to be compiled, but some or all of the internal calls to FFmpeg fail at run time (they report an error and processing continues, but without any output).

For many packages, that would be a critical error. In this case, the main reason to install Transcode is for the tccat program, which works. Some of the transcode options work - for the others, use ffmpeg directly on the command line.

If building with --enable-freetype2 configure switch, use the following sed to fix building against FreeType-2.5.1 or newer versions:

sed -i "s:#include <freetype/ftglyph.h>:#include FT_GLYPH_H:" filter/subtitler/load_font.c

Install Transcode by running the following commands:

sed -i 's|doc/transcode|&-$(PACKAGE_VERSION)|' \
       $(find . -name Makefile.in -exec grep -l 'docsdir =' {} \;) &&

sed -i "s:av_close_input_file:avformat_close_input:g" \
       import/probe_ffmpeg.c                                       &&

patch -Np1 -i ../transcode-1.1.7-ffmpeg2-1.patch                   &&
./configure --prefix=/usr \
            --enable-alsa \
            --enable-libmpeg2 &&
make

This package does not come with a test suite.

Now, as the root user:

make install

Command Explanations

sed -i ...: Fixes install location for documentation.

sed ... import/probe_ffmpeg.c: This sed fixes compilation with ffmpeg-2.4 or newer versions.

Support for most of the dependency packages requires using options passed to the configure script. View the INSTALL file and the output from ./configure --help for complete information about enabling dependency packages.

Short Descriptions

avifix

fixes the header of an AVI file.

aviindex

writes a text file describing the index of an AVI file.

avimerge

merges AVI files of the same format. Do not try to merge AVI files of different formats, it will most likely result in errors (and format means same bitrates, too!).

avisplit

splits AVI files into multiple files.

avisync

can shift audio in AVI files for better synchronizing of the audio and video data signal.

tccat

concatenates input files using the input plugins of Transcode. This is useful for extracting VOB (Video OBject) files.

tcdecode

is used to decode input files to raw video and PCM audio streams.

tcdemux

demultiplexes (separates) audio/video input that contains multiple streams, e.g., VOB files.

tcextract

grabs single streams from a file containing multiple streams.

tcmodinfo

loads a supplied Transcode filter module and prints its parameters.

tcmp3cut

is a tool which can cut MP3 streams at milliseconds positions.

tcprobe

prints information about the input file format.

tcscan

performs several measurements on the given input data.

tcxmlcheck

checks information in a SMIL input file.

transcode

is the encoder's user interface that handles the plugins and other programs, being the glue between the modules. There are several well documented usage examples on both the homepage and the documentation included in the package.
