Also use the frame pixel format instead of the one from the codec
context, which is more robust.

The AVFrame values are closer to the AVFrame bitmap changed instead of
the AVCodecContext values, so this should be more robust

h264: update the current bit depth/chroma type in init_slice_header()
Merged-by: Michael Niedermayer <michaelni@gmx.at>
It does not make sense to copy is_avc without copying this as well. This
patch should not change anything for now, but will have an effect in
later commits.
That function currently does two things -- reinitializing the DSP
contexts and setting low_delay based on the SPS values.
The former more appropriately belongs in h264_slice_header_init(), while
the latter only really makes sense in decode_slice_header().
The third call to ff_h264_set_parameter_from_sps(), done immediately
after parsing a new SPS, appears to serve no useful purpose, so it is
just dropped.
Also, drop now unneeded H264Context.cur_chroma_format_idc.
Currently, the DPB is initialized in alloc_tables() and uninitialized in
free_tables(), but those functions manage frame size-dependent
variables, so DPB management does not logically belong in there.
Since we want the init/uninit to happen exactly once per the context
lifetime, init_context()/free_context() are the proper place for this
code.
YCgCo decoding works just fine. It depends on the API user what is done
with the output. Some API users might support it, some not. Some users
might support it under certain circumstances only.
It is not the job of the decoder to print this message. If the API user
supports it, this message is extremely unhelpful.
