Roadmap for version 1.14 Expand all | Collapse all

12%

12% of 15 tasks completed. 15 open tasks:

FS#125 - Blank screen evasion (mtn feature) Expand Collapse

Great feature, implemented in mtn

http://moviethumbnail.sourceforge.net/

-o is a GNU extension, supported in Linux and FreeBSD

Unsupported in SunOS, OpenBSD?

FS#56 - Add transcode as possible capturer Expand Collapse

Originally requested by Phil Grundig

See vcs:devel:transcode

FS#147 - Configuration options revamp Expand Collapse

The available configuration options need a serious review and renaming. Old names will be accepted with warnings for either two releases or six months.

Also, should provide a sample configuration file so that the syntax and options are clearer.

FS#151 - Override-able variables cleanup: Removal of deprecated names Expand Collapse

Introduce new names in 1.12 ( ~~FS#120~~ )

Remove old names in 1.13 or 1.14 (this)

FS#172 - Don't autoload './vcs.conf' Expand Collapse

See ~~FS#171~~

FS#178 - ffmpeg + piped mplayer dump can be used to identify Expand Collapse

Originally suggested by Dean: http://outlyer.net/2010-08-24:vcs-1_12-2-released/

Second, my dvd-drive is useless atm, but i remember previously piping dvd-ouput from mplayer into ffmpeg via a fifo and finding the info generated to be much better than mplayer-alone – for one thing, it won't 'downmix' 6-channel audio automatically. Don't know if that would be useful to you. The syntax was something like:-

mkfifo piped.vob &&
mplayer dvd:// -dumpstream -dumpfile piped.vob & \
ffmpeg -i piped.vob

…See what you think…

FS#196 - ffmpeg is deprecated Expand Collapse

See http://libav.org/, Jan 27 2012.
Also http://libav.org/index.html#fftools_rename for changes to the syntax.

Must change to avprobe/ffprobe and/or avconv.

FS#197 - Move away from /dev/shm Expand Collapse

/dev/shm isn't really intended as an alternate temporary location, and VCS' temporary files can easily grow too large for it too.

As a possible alternative offer a first-run choice of temp-dir (maybe suggesting /dev/shm).

FS#227 - Failed blank frame evasion should go back to original timestamp Expand Collapse

When a frame evasion is tried and given up, the chosen timestamp should be the original instead of the last attempt

FS#249 - Add libav as possible capturer Expand Collapse

No need for description

FS#363 - File names with '#' lead to errors when creating versioned outpu Expand Collapse

I.e. create file sample#.avi

Run vcs on sample#.avi -> sample#.avi.png is created.
Run vcs again. sample#.avi-1.png should be created, but sed generates an error.

FS#367 - Add HDR support Expand Collapse

HDR isn't well supported as reported by remlap and ThaDr.

Hi I am trying to thumbnail some HDR content is there anyway to insert ffmpeg filters in
-vf zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=mobius:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p

Thanks

I'm also trying to do some HDR content and pass the -vf info to ffmpeg. I can't get it to work even using a wrapper script.

It always comes up with awk errors, starting with "unterminated regexp".

Is there any chance of updating vcs to support manual passing of those -vf arguments to ffmpeg?

HDR content is very common nowadays…

https://outlyer.net/2017-05-26:vcs-1-13-3-released/#comment-32423

I'm using vcs 1.13.2 on ubuntu and ended up doing it by adding the line:

-vf 'zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p' \

at line 2203, in the ffmpeg_capture() function where it sets the ffmpeg command line options.

Couldn't work out how to do it with a wrapper script.

FS#375 - Allow disabling blank frame evasion Expand Collapse

Should allow to disable it in both configuration and command-line.

FS#378 - Blank frame evasion produces error on latest ImageMagick Expand Collapse

Reported by Paul:

Hey,
I'm using VCS via Homebrew Install (https://formulae.brew.sh/formula/vcs#default) and since the last update of imagemagick (?) I get dozens of error messages:
convert: Expected operator at '.mean*100' @ error/fx.c/GetOperator/2408

Confirmed to happen on ImageMagick 7.1 on Linux, the contact sheet is generated but blank frame evasion is skipped

Roadmap for version 2.0 Expand all | Collapse all

0% of 2 tasks completed. 2 open tasks:

FS#92 - Support OpenSolaris/SunOS Expand Collapse: Being based on System V, it's quite different to most other Unix-like OSes, might be a good target for x-platform enhancements
FS#162 - Implement plugins Expand Collapse: No need for description

Roadmap for version ? Expand all | Collapse all

FS#52 - Allow review of screenshots before composing Expand Collapse

FS#163 - Move rarely used features to plugins Expand Collapse

No need for description

FS#164 - Implement instrumentation Expand Collapse

No need for description

FS#194 - Files incorrectly reporting "too short" length aren't detected Expand Collapse

As reported by Dirk Reiners (paraphrased)

Files incorrectly reporting too short length (unlike too long), pass the safe_length_measure check ⇒ This prevents correcting length.

FS#315 - Recurse directories, output to current dir Expand Collapse

Request by Chris Hills

http://outlyer.net/2014-05-18:vcs-1_13_2-released/comment-page-1/#comment-17238:

Thanks Toni. I was hoping I could simply run `$ vcs-1.13.2.bash -? **/*.mp4` to create contact sheets for all videos in all subfolders, but it sounds like I'll have to use a wrapper script. Would you consider adding this in a future release for a donation?

My reply:

I guess you're using zsh-ish globbing there.
That's not something I use so I didn't even think of the case where recursing could be so simple.

It was a bit of an overlook on my part not to have the option to output to the same directory as the video, probably because recursion always required a wrapper in my head.

FS#377 - Allow screenshotting half of the video (for side-by-side VR vide Expand Collapse

Asked by Bob on the blog

Would it be possible to somehow specify to only screenshot half of the video image (for 180 side-by-side VR videos)?

Or would this require new features to be added to the VCS?

FS#382 - Look into detecting or setting manually GNU getopt Expand Collapse

Reported by KW in comments: https://outlyer.net/2019-11-26:vcs-1-13-4-released/#comment-51875

With the new script I'm getting issues the following error:
No compatible version of getopt in path, can't continue.
Enhanced getopt (i.e. GNU getopt) is required

Added by Darko in comments: https://outlyer.net/2019-11-26:vcs-1-13-4-released/#comment-52719

The homebrew's version of vcs has this at line 186:
declare GETOPT=/opt/homebrew/opt/gnu-getopt/bin/getopt
While Toni's just uses whatever is on path:
declare GETOPT=getopt
… which on macOS is non-gnu version of getopt.

Added by X in comments: https://outlyer.net/2019-11-26:vcs-1-13-4-released/#comment-53401

The issue is on line 186. Brew version has this:
declare GETOPT=/usr/local/opt/gnu-getopt/bin/getopt
The trunk version has:
declare GETOPT=getopt
When I backport the most important change you did in the trunk version ('`fx:image.mean` > `fx:mean`') then indeed the error messages on '.mean*100' are gone.
