IPBT
IPBT (It's Play-Back Time) is a curses-based
playback utility for recordings of terminal sessions in either ttyrec
or nh-recorder format. This utility analyses the entire
ttyrec file before beginning the playback, and reorganises it into a
form which permits frame-by-frame forward and backward replay. This
enables
you to press pause and back up frames if something in the recording
takes your interest.
IPBT works by embedding a terminal emulator: it is essentially
a derivative work of the PuTTY code base. The input file is read in
full and run through the internal terminal emulator, and the
resulting screen states are saved in an internal movie array in such
a way that any screen state (`frame') can be retrieved
efficiently.
Once this is done, the player application simply displays a
sequence of frames using libncurses; the user can perform the usual
pause and
speed adjustment operations, but can also jump to an arbitrary frame
number and move backwards as well as forwards.
Features include:
- Rewind files
- Play at linear or logarithmic speed. Logarithmic mode can
be used in conjunction with the ‘x’/‘X’ scaling feature
- Jump to specific frames
- On-screen display
- Pause mode
- Search forwards and backwards
- Full-screen playing mode
- Search the recording for a frame in which a particular
piece of text appears on the screen
