[libdv-dev] segmentation fault using libdv-0.8

[Christoph S. <ch...@ne...>]

Hello,

I extended lav2yuv from the MJPEG project on sourceforge to read DV files. It
worked nicely so far, but now I ran into a problem with libdv and I don't
know where it really comes from. I am using libdv-0.8 and I built the modified
lav2yuv with this version before and didn't have any problems.

I built lav2yuv again from a clean CVS checkout which went without problems
but when I try to use lav2yuv with DV input I receive a Segmentation fault. I
ran it through the debugger and got a surprising result: the segmentation
fault is from within libdv which never occured before. The debugger says the
problem is in:
    dv_quant_init () at quant.c:153
    /usr/local/src/libdv-0.8/libdv/quant.c:153:3119:beg:0x8058ea4
and the offending line in the source is:
    quant_248_inverse = quant_248_inverse_std;
Does anybody know what could cause the problem? I am running Debian woody with
gcc 2.95.3 and nasm version 0.98.

Any help is appreciated,

Christoph
