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.

Running in Fedora Core 10 i686 (KVM) yields one 128k frame less and a different “theoretical size” than in Debian amd64, in one sample, and the same number of frames but 2 bytes less in another.

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.

finger is not installed/enabled by default in at least FC12. Replace it with something better like grepping /etc/passwd

Due to the use of ~ in the revision tag

When the resulting contact sheet is too thin, the meta-information header is cramped and fields overlap.

Useful for debugging, likely not useful for users since the command-line already overrides configurable arguments

It just makes more sense

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?

Meta-task depending on tasks scheduled for the 1.4 release.

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…

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.

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.
