[XviD-devel] create.zones never freed after XVID_ENC_CREATE in VFW

[Bryan Mayland]

Was reading through the VFW source (to port the zones implementation to 
transcode) and I've noticed that the zones array passed in during 
XVID_ENC_CREATE is never freed:
/vfw/src/codec.c:518
    create.zones = malloc(sizeof(xvid_enc_zone_t) * tmpCfg.num_zones);

These zone structs are passed to xvid_encore_func() on line 576.  XViD 
will malloc its own memory and copy them from passed create struct.  
Therefore they should be freed upon return.  Easiest fix:
    i = codec->xvid_encore_func(0, XVID_ENC_CREATE, &create, NULL);
    free(create.zones);
    create.zones = NULL;
    switch(i)
    ...

Pretty minor, but thought I'd point it out.
