vcs

Version 1.12.3 breaks on FreeBSD due to the usage of GNU-specific extensions of expr, sed and an incompatible Bash RE.

The filmstrip mode has had a placeholder implementation since the start, it should look closer to an actual film strip.

E.g.: http://sites.google.com/site/elsamuko/gimp/sprocket

As found in mtn.

Try to avoid capturing mostly-blank frames.

As reported by Dirk Reiners (paraphrased)

When steps get too small they might round to 0 ⇒ infinite loop in compute_timecodes.

At least on some systems, the console/terminal needs a manual reset (or tset) to be usable after running vcs.

When repeated captures are avoided, captures end up being filtered more than once

Currently the extended set always contains the standard captures. It might be nice to add some time-shift to them so that they’re different.

See also  FS#122 

When a timestamp is present in more than one set (highlights/std/extended) there’s no need to re-capture it.

Internal: Stale code from prior versions, numsecs inside process() uses mplayer’s value instead of the best value to determine video length (and keep or discard timestamps).

As a side-effect, newer code being more strict about array vs string handling can fail easily.

Parsing of the “-U” option (optional argument) is incorrect, it always receives an argument (empty if none provided) which must be shifted manually. Currently it’s only shifted if provided explicitly.

“–fullname” is not affected since it doesn’t take any arguments.

Bash 2 syntax has been the norm for most versions (although broken in some).

So far none of the major distributions is using bash 2, bash 4 is already gold but not widely-used enough.

Only a few special purpose/minimal distros like DSL retain bash 2.05b, but vcs requires recent versions of ImageMagick, Mplayer and FFmpeg anyway. I can’t see a reason to retain such backwards compatibility.

Configuration options that will trigger a change of all fonts, background and foreground settings respectively

font_filename is ignored in 1.12

An alternative in the form of (boolean) nonlatin_filenames or similar should be added.

Uses VP8 video and Vorbis audio.

Current Status:

Identification

MPlayer: Video detected as VP80
FFmpeg:
* 0.5.1+svn20100311: Not supported (fails in the safe-length-detection stage)
* 0.6~svn20100603: Video detected as libvpx

Capture

Both appear to work fine.

VCS’ temporary dir (and its contents) is not removed on cleanup. Space in /dev/shm is wasted as a result.

Patch attached.

-I does use it

Implementation notes:

• Reserved namespace: :<WHATEVER>
• Built-in profiles won’t use reserved names
• System profiles will always take precedence over built-in profiles
• ~ profiles take precedence over site (/usr and /usr/local) profiles
• /usr/local takes precedence over /usr. Both are searched
• No such thing as a default profile (this would be redundant to configuration files)
• Profiles can’t depend/include/load other profiles
• Profile names are reflected in file names

Specific files will be loadable with --config

Markup

Introduce new names in 1.12 (this)

Remove old names in 1.13 or 1.14 (FS#151)

End offset will be set to a small percentage of the length (5.5%? –5m for 90m–), applicable always by default, instead of a fixed value
