I tried disabling audio to no avail... RossClement - what cmd line should I use with ffmpeg?

>>> Starting magick
>>> Trying /home/wilsonc/001.kinofx.dv
[dv @ 0x5bf6f04]Can't initialize DV format!
Make sure that you supply exactly two streams:
video: 25fps or 29.97fps, audio: 2ch/48Khz/PCM
(50Mbps allows an optional second audio stream)

Kino experienced a segmentation fault.

Sorry rapid, I only just saw this.

Problem is, I can't be sure what to do as I installed ffmpeg from source, and now can't reproduce the bug.

Please run the following ffmpeg line:

 ffmpeg -i blah.dv -vcodec copy -acodec copy -b 200K blah2.dv
on the attached blah.dv (packaged in blah.tar) file.

My reasoning (quite possibly mistaken) is that ffmpeg was refusing to handle any dv video without stereo audio attached. blah.dv doesn't have an audio stream, so should reveal the error. The bitrate parameter is just there so that the DV video needs to be reencoded. In case the "copy" "copy" makes ffmpeg just do a bitwise copy of the streams.

If this crashes with an error about the video streams, then you have a problem with ffmpeg. Otherwise, it might be just kino.
