This is a repeating callback because the field:
  EncryptedMediaInitDataCB encrypted_media_init_data_cb_
defined in:
  https://cs.chromium.org/chromium/src/media/filters/chunk_demuxer.h?rcl=44124afc1e06fad84a6e6df7b728f80c6de5b5ac&l=477
binds in:
  https://cs.chromium.org/chromium/src/media/filters/chunk_demuxer.cc?rcl=44124afc1e06fad84a6e6df7b728f80c6de5b5ac&l=674
against a base::RepeatingCallback declared in:
  https://cs.chromium.org/chromium/src/media/filters/source_buffer_state.cc?rcl=44124afc1e06fad84a6e6df7b728f80c6de5b5ac&l=152
to a type alias defined in:
  https://cs.chromium.org/chromium/src/media/base/stream_parser.h?rcl=44124afc1e06fad84a6e6df7b728f80c6de5b5ac&l=108

This is part of the base::Callback migration.
