[vlc-devel] [PATCH] avcodec: remove deprecation warning for av*_register_all

[Alexandre Janniaux]

>From doc/APIchanges:

    2018-02-06 - 0694d87024 - lavf 58.9.100 - avformat.h
      Deprecate use of av_register_input_format(), av_register_output_format(),
      av_register_all(), av_iformat_next(), av_oformat_next().
      Add av_demuxer_iterate(), and av_muxer_iterate().

    2018-02-06 - 36c85d6e77 - lavc 58.10.100 - avcodec.h
      Deprecate use of avcodec_register(), avcodec_register_all(),
      av_codec_next(), av_register_codec_parser(), and av_parser_next().
      Add av_codec_iterate() and av_parser_iterate().

They are no-op since those updates. If compiling with a recent release,
just don't call av*_register_all to prevent warnings.
