[FFmpeg-devel] [PATCH 12/12] avcodec/mpegvideo: Move allocating new_picture to the encoder

[Andreas Rheinhardt <andreas.rheinhardt@outlook.com>]

It is only used by encoders; this unfortunately necessitated
to add separate allocations to the SVQ1 encoder which uses
motion estimation without being a full member of mpegvideo.
