Task Description

Fails on some files (gets stuck forever while capturing the first frame).

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

Works on avi, mpg and mp4 but fails on wmv with
Failed to capture frame (at second xxx.000)

Processing the same file directly works:

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.

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:

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.

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…
