tcscan - scan multimedia streams from medium and print information on the standard output

tcscan
-i name [ -x codec ] [ -e r[,b[,c]] ] [ -b bitrate ] [ -w num ] [ -f rate ] [ -d verbosity ] [ -v ]

tcscan is part of and usually called by transcode.
However, it can also be used independently.
tcscan reads source (from stdin if not explicitely defined) and prints on the standard output.

-i name
Specify input source. If ommited, stdin is assumed.
You can specify a file, directory, device, mountpoint or host address as input source. tcscan usually handles the different types correctly.
-d level
With this option you can specify a bitmask to enable different levels of verbosity (if supported). You can combine several levels by adding the corresponding values:

QUIET 0

INFO 1

DEBUG 2

STATS 4

WATCH 8

FLIST 16

VIDCORE 32

SYNC 64

COUNTER 128

PRIVATE 256

-v
Print version information and exit.

tcscan is a front end for scaning various source types and is used in transcode's import modules. tcscan does a complete scan of the source to gather information.

The command tcscan -i foo.avi prints header information about the AVI-file itself and lists details on the video and audio content, e.g., keyframes, chunk structure.

The command cat audio.pcm | tcscan -x pcm -e 48000,16,2 simply determines the playtime lenghth of the raw audio stream.

The command tcscan -x mp3 -i input.mp3 will print the number of chunks in the MP3 file and the average bitrate.
