dashdec: Fix segfault on decoding segment timeline · 4e3e8980

Brendan McGrath authored Jan 29, 2018

If first_seq_no is not within the bounds of timelines then a segfault
will occur.
This patch removes the use of first_seq_no within the timelines array
It also adds first_seq_no to the value returned by calc_next_seg_no_from_timelines
(which allows for different values of 'startNumber')

avfilter/vf_framerate: change blend factor precision · 2cbe6bac

Marton Balint authored Jan 15, 2018

This is done mainly in preparation for the SIMD patches.

- for the 8-bit input, decrease the blend factor precision to 7-bit.
- for the 16-bit input, increase the blend factor precision to 15-bit.
- make sure the blend functions are not called with 0 or maximum blending
  factors, because we don't want the signed factor integers to overflow.

Fate test changes are due to different rounding.

Currently the resource is only ever unregistered when the

I'm pretty sure the frame will have been cleaned up before that happens,
so I'm kinda surprised this never blew up.
