Hi guys
In file libavfilter/drawutils.c there is a function called clip_interval
static void clip_interval(int wmax, int *x, int *w, int *dx)
what does the parameter means over here, means what is x and what is w
wmax is understood to me.
I came over here, since valgrind showed me that I am using
uninitialized memory.
Thanks

Hi
In source code there is reallocation of memory
935 if ((len = s->expanded_text.len) > s->nb_positions) {
936 if (!(s->positions =
937 av_realloc(s->positions, len*sizeof(*s->positions))))
938 return AVERROR(ENOMEM);
939 s->nb_positions = len;
and I didn't found any initialization of positions, and we are using
uninitialized position
in clip filter.
would it be ok to initialize just after allocating the memory.
Thanks
Anshul
