[FFmpeg-devel] [PATCH 2/2] avcodec/dvenc: Don't set chroma_sample_location

[Andreas Rheinhardt]

The documentation specifies that it is set by the user
for encoders. Given that ff_dvvideo_init() is so extremely simple,
the fix consists of inlining the function into its two callers,
with setting chroma_sample_location omitted in dvenc.c.

This unfortunately leads to the color siting element written
in the mxf_dv25 test being unknown.
