This is a meta-item depending on bugs/features required to complete before releasing vcs 1.12.1

This is a meta-item depending on bugs/features required to complete before releasing vcs 1.12.2.

1.12.2 might be skipped and its items pushed back to 1.13.

WebM: http://www.webmproject.org/

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.

Originally submitted by Jason Tackaberry

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

Patch attached.

No need for description

Bugfixes from the 1.13 branch should be backported to 1.12, since 1.13 will need a lot of testing.

Previous:  FS#165 
Next:  FS#152 

The function that vcs.conf in current dir accomplished is covered by profiles. If wanted it can still be manually loaded with -C :pwd or -C vcs.conf

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.

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.

Originally reported by Robert Speicher.

Works for awhile, then starts failing until reboot. Happens with 1.12.1, but continued to fail after upgrade to 1.12.2.

Every capture from here on out will fail in a similar fashion until reboot.

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

Safe length measuring, when probing the video length, prints only the number of seconds and milliseconds, it would be better to display a more readable format.

mplayer: FPS1

i.e.:
ID_VIDEO_CODEC=fffraps
ID_VIDEO_FORMAT=FPS1

ffmpeg: fraps

i.e.:
Stream #0.0: Video: fraps, yuvj420p, 1680x1050, 30 fps, 30 tbr, 30 tbn, 30 tbc

Sometimes a negated type will be ignored.

e.g.:

Fine:

$ relevation -t website java.net

-> Search "java.net" ('website' entries):  1 matches

$ relevation -t -website java.net

-> Search "java.net" ('not website' entries):  No results

Not fine:

$ relevation google.com

-> Search "google.com" ('not folder' entries):  6 matches

$ relevation google.com | grep -c ^Type:\ website
5

$ relevation -t -website google.com

-> Search "google.com" ('not website' entries):  6 matches
$ relevation  -t -website google.com | grep -c ^Type:\ website
5

$ relevation -t website google.com

-> Search "google.com" ('website' entries):  5 matches

Might be due to entries inside folders being repeated?

When the decryption password is wrong a zlib exception is raised:

Should handle more gracefully

Meta-task depending on tasks scheduled for the 1.1 release

PyCryptoPlus is a drop-in replacement for PyCrypto written in Python, meaning it can run much more easily on Windows.

lxml provides a cleaner (or more pythonic) implementation, is easier to install and more commonly required.

cryptopy provides a pure python implementation of ciphers, allowing easier install on some systems (e.g. 64bits Windows) than PyCrypto.
Unlike PyCryptoPlus it doesn’t seem to depend on PyCrypto but has a different API.

The performance degrades considerably, of course.

Meta-task depending on tasks scheduled for the 1.2 release

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.

As found in mtn.

Try to avoid capturing mostly-blank frames.

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

As reported by Dirk Reiners (paraphrased)

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