SubTimer is "A subtitle timing utility for Linux written in Qt, much like SubStation Alpha on Windows. Handles editing of various subtitle formats and timing with the help of an audio file." The strange thing is the need of an .ogg file with audio data. There is no "video" support, although it supports .ssa and .srt subtitles. The latest version is 0.33, released on 2007-02-03. I've just tried to compile it manually. It does not use "configure" scripte. To compile, I needed to type: export PATH="$QTDIR/bin:$PATH" # Where QTDIR was already /usr/qt/3 make subtimer Running "make" without parameter show the possible make targets. It requires app-doc/doxygen for building (optional) documentation. I don't plan to make an ebuild for this. If someone gets interested into adding this to portage, please, go on. If nobody gets interested after some time, I think you should close this bug (as INVALID, WONT or LATER).
Just to make the work of the maintainer easier, it requires: media-libs/libvorbis media-libs/alsa-lib x11-libs/qt version 3 app-doc/doxygen (for optional documentation) I think these are all dependencies needed at compile time (note that doxygen is not needed at runtime). It also comes with a little mp32ogg application which uses TCL/TK (/usr/bin/wish), but is not required for normal subtimer use. I also suggest applying this patch before compiling: https://sourceforge.net/tracker/?func=detail&atid=732533&aid=1726203&group_id=135323 (BTW, I am the author of this patch)
It requires Qt 3 which is long gone.
