The transcode package contains transcode, tccat, tcdecode, tcdemux, tcextract, tcframe, tcprobe, tcscan, avicodec, avidump, avimerge, avisplit, avisync and a merry lot of input/filter/output modules. 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 concatenates input files using the input plugins of transcode. tcdecode is used to decode input files to raw video and pcm audio stream. tcdemux demultiplexes audio/video input that contains multiple streams, e.g. VOB-files. tcextract grabs single streams from a file containing multiple streams. tcframe processes single video frames for different color encodings (RGB >-< YUV or similar). tcprobe prints information about the input file format. tcscan performs several measurements on the given input data. avicodec indicates or changes FOURCC codec flag in an .avi file. avidump dumps audio or video stream of an given avifile to stdout (for avi conversion or extraction of audio streams). 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 audio and video data signal. 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 filetype of choice.
