Installation of transcode

Install transcode by running the following commands: 

./configure --prefix=/usr --without-x &&
make &&
make install

Command explanations

--without-x: Omit this switch if you have X Window System installed and you want to compile X11 dependent filter plugins.

Description

transcode

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 either the homepage or the documentation included in the package.

tccat

tccat concatenates input files using the input plugins of transcode.

tcdecode

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

tcdemux

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

tcextract

tcextract grabs single streams from a file containing multiple streams.

tcframe

tcframe processes single video frames for different color encodings (RGB >-< YUV or similar).

tcmodinfo

tcmodinfo loads a supplied transcode filter module and prints its parameters.

tcmp3cut

tcmp3cut is a tool which can cut MP3 streams at milliseconds positions.

tcprobe

tcprobe prints information about the input file format.

tcrequant

tcrequant is a tool which can requantize an MPEG-2 elementary stream.

tcscan

tcscan performs several measurements on the given input data.

tcxmlcheck

tcxmlcheck checks information in a SMIL input file.

avicodec

avicodec indicates or changes FOURCC CODEC flag in an AVI file.

avidump

avidump dumps audio or video stream of an given AVI file to stdout (for AVI conversion or extraction of audio streams).

avifix

avifix fixes the header of an AVI file.

aviindex

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

avimerge

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

avisplit splits AVI files into multiple files.

avisync

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

input/filter/output modules

Depending on the external libraries that are used, there are a great number of plugins to convert audio and video input to raw format, process raw video and audio and convert raw audio and video to other formats to be written into a file type of choice. Read the documentation.
