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

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?

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.

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.

197TO-DOHighMove away from /dev/shmAssigned
0%
1.14 Task Description

/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).

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

” [...]

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…

137Bug ReportMediumHang with RM filesUnconfirmed
0%
Task Description

Original report by Dougn Redhammer

vcs hangs with some RM files.

Tracing shows it gets stuck in mplayer_identify.

MPlayer can play the files fine from the terminal. Although it exits with «MPlayer interrupted by signal 11 in module: uninit_vcodec».

I can reproduce the abrupt termination, it happens when using Real’s native decoder (w64codecs, /usr/lib/codecs/drvc.so). Using FFMpeg’s decoder (MPlayer’s -vc ffrv30) MPlayer exits normally.

I can’t reproduce the hang either way.
