* commit 'b5849f77095439e994b11c25e6063d443b36c228': (21 commits)
  ac3enc: merge AC3MDCTContext with AC3EncodeContext.
  ac3enc: prefer passing AC3EncodeContext rather than AVCodecContext
  ac3enc: fix memleak
  mpeg1video: add CODEC_CAP_SLICE_THREADS.
  lavf: fix segfault in av_open_input_stream()
  mpegtsenc: set Random Access indicator on keyframe start packets
  lavf: Cleanup try_decode_frame() logic.
  Replace some gotos that lead to single return statements by direct return.
  build: move tests/seek_test.c to libavformat and reuse generic build rules
  mxfenc: include needed header for ff_iso8601_to_unix_time() prototype
  Add a check for strptime().
  lavf: factor out conversion of ISO8601 string to unix time
  wav: parse 'bext' metadata
  wav: keep parsing until EOF if the input is seekable and we know the size of the data tag
  wav: Refactor the tag checking into a switch statement
  wav: make sure neither data_size nor sample_count is negative.
  wav: refactor the 'fmt ' tag search and parsing.
  wav: add an option for writing BEXT chunk
  ffmpeg: get rid of a pointless limit on number of streams.
  ffmpeg: remove an unused define.
