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…

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

Happens often with Matroska. 1.0.7a introduced a workaround (-Wo) with ffmpeg’s argument order that worked with other file types.

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.

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).

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

https://outlyer.net/2017-05-26:vcs-1-13-3-released/#comment-32413:

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.

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.
