* lavc/dvdsubenc: accept palette from optionsMichael Kuron2020-02-04
| | | | | | | | Previously, the default palette would always be used. Now, we can accept a custom palette, just like dvdsubdec does. Signed-off-by: Michael Kuron <michael.kuron@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* mlp: check huff_lsbs only when codebook is usedJai Luthra2020-02-04
| | | | | | | When no codebook is used, huff_lsbs can be more than 24 and still decode to original values once filters are applied. Signed-off-by: Jai Luthra <me@jailuthra.in>

| | | | | | | | | * fix a possible memory leak (apply_filter returned before freeing) * use apply_filters in process_major_frame * revert back to checking bounds with 24 bitdepth, as huff offset takes care of it Signed-off-by: Jai Luthra <me@jailuthra.in>
