[Mjpeg-users] mpeg2enc segmentation fault

[Soren T. <so...@ti...>]

I just downloaded libdv-0.9.5 *.rpm (from the official site) and the 1.6.0
mjpegtools in source form. I've installed libdv and compiled/installed
mjpegtools. Now when I try to convert a DV format .avi to .mpg the mpeg2env
utility segfaults. Would anybody have any idea what's going on and what I
should do to get it to work? Here are a few more details: This is for a DV
capture (using dvgrab) of four frames. Just a demo. Mpeg2enc appears to
crash no matter the length of the file.
