dashenc: check pts to prevent division by zero error
this usecase will cause a division by zero trap: 1. dashenc has received one frame 2. os->max_pts and os->start_pts have same value 3. delta between max_pts and start_pts is 0 4. av_rescale_q(0, x, y) returns 0 5. this value is used as denominator in division 6. Bang! -> segfault this fix checks that max_pts > start_pts. the fix has been tested and works. Signed-off-by: Alfred E.
