Before this commit v4l2_m2m used two different logging contexts (from
V4L2m2mPriv and AVCodecContext). For consistency always use AVCodecContext.

Before this commit s->avctx == NULL was used to infer that an encoder is
being initialzed. Code readability has been improved by directly using
!av_codec_is_decoder() instead.

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.
