ab905f1dbc avcodec/Makefile: Make H.263 decoder compilable without H.263I
The only call to ff_intel_h263_decode_picture_header() is already behind
"if (CONFIG_H263I_DECODER)".

d64828c8af avcodec/Makefile: Remove FLAC dependencies on vorbis_data
2ef2496cd19eb833f4ad22a5051c11be80d09598 used ff_vorbis_channel_layouts
in flac.c, but added a dependency to the FLAC decoder only; lateron
aba0278e9fe8e66c078588efe66f6af4db432770 added the dependency of the
FLAC parser and encoder on vorbis_data.o. Yet when the original commit
was reverted in aba0278e9fe8e66c078588efe66f6af4db432770, the two other
dependencies were not removed. This commit fixes this.

a423bc9dc2 ffmpeg_opts: remove lowres check
The st->codec values are updated based on the lowres factor by
avformat_find_stream_info() when it runs an instance of the decoder internally,
and the same thing happens in ffmpeg.c when we open ist->dec_ctx with
avcodec_open2(), so these assignments are redundant.

Alternatively this could be ignored but then the end condition of the loop
would be hard to reach as avio_tell() is int64_t

71b82e4ffd dnn/openvino: support model input resize
OpenVINO APIs require specify input size to run the model, while some
OpenVINO model does accept different input size. To enable this feature
adding input_resizable option here for easier use.
Setting bool variable input_resizable to specify if the input can be resizable or not.
input_resizable = 1 means support input resize, aka accept different input size.
input_resizable = 0 (default) means do not support input resize.
Please make sure the inference model does accept different input size
before use this option, otherwise the inference engine may report error(s).
eg: ./ffmpeg -i video_name.mp4 -vf dnn_processing=dnn_backend=openvino:\
      model=model_name.xml:input=input_name:output=output_name:\
      options=device=CPU\&input_resizable=1 -y output_video_name.mp4
