      pcm_dvd: consolidate pieces from pcm.c and mpeg.c · a42e3a67
      Christian Schmidt authored
      Remove the header decoding for PCM audio from mpeg.c and the
      20/24bit parts from pcm.c and merge them into a new decoder in
      pcm-dvd.c.
      
      The decoder has added support for samples that span multiple
      packets and modified 20/24bit group decoding. Both is needed to
      decode samples that have been generated with DVD-Lab Pro 2. The
      decoding of 16bit PCM and two channel 24bit is identical to
      before. No other samples are known to verify the correctness of
      the encoding this software does.
      The complete list of tested formats is
      48kHz/16bit/2-8 channels
      48kHz/24bit/2-5 channels
      96kHz/16bit/2-4 channels
      96kHz/24bit/2 channels

      pcm_bluray: rename pcm-mpeg.c to pcm-bluray.c · 0d6549d8
      Christian Schmidt authored
      The original idea was to collect PCM codecs that could appear in various
      MPEG streams in this file. Discussion in IRC lead to the conclusion that
      one codec per file would be better and stop the need for #ifdefs.

      Add a libfdk-aac decoder · 4f2b469d
      Martin Storsjö authored
      This can be useful for decoding AAC object types that are not supported
      by the native AAC decoder, e.g. AAC-LD and AAC-ELD.

      libavutil: Make avpriv_open a library-internal function on msvcrt · e743e7ae
      Martin Storsjö authored
      Add one copy of the function into each of the libraries, similarly
      to what we do for log2_tab. When using static libs, only one
      copy of the file_open.o object file gets included, while when
      using shared libraries, each of them get a copy of its own.
      
      This fixes DLL builds with a statically linked C runtime, where
      each DLL effectively has got its own instance of the C runtime,
      where file descriptors can't be shared across runtimes.
      
      On systems not using msvcrt, the function is not duplicated.

      subtitles: introduce ASS codec id and use it. · 7c1a002c
      Clément Bœsch authored
      Currently, we have a AV_CODEC_ID_SSA, which matches the way the ASS/SSA
      markup is muxed in a standalone .ass/.ssa file. This means the AVPacket
      data starts with a "Dialogue:" string, followed by a timing information
      (start and end of the event as string) and a trailing CRLF after each
      line. One packet can contain several lines. We'll refer to this layout
      as "SSA" or "SSA lines".
      
      In matroska, this markup is not stored as such: it has no "Dialogue:"
      prefix, it contains a ReadOrder field, the timing information is not in
      the payload, and it doesn't contain the trailing CRLF. See [1] for more
      info. We'll refer to this layout as "ASS".
      
      Since we have only one common codec for both formats, the matroska
      demuxer is constructing an AVPacket following the "SSA lines" format.
      This causes several problems, so it was decided to change this into
      clean ASS packets.
      
      Some insight about what is changed or unchanged in this commit:
      
        CODECS
        ------
      
        - the decoding process still writes "SSA lines" markup inside the ass
          fields of the subtitles rectangles (sub->rects[n]->ass), which is
          still the current common way of representing decoded subtitles
          markup. It is meant to change later.
      
        - new ASS codec id: AV_CODEC_ID_ASS (which is different from the
          legacy AV_CODEC_ID_SSA)
      
        - lavc/assdec: the "ass" decoder is renamed into "ssa" (instead of
          "ass") for consistency with the codec id and allows to add a real
          ass decoder. This ass decoder receives clean ASS lines (so it starts
          with a ReadOrder, is followed by the Layer, etc). We make sure this
          is decoded properly in a new ass-line rectangle of the decoded
          subtitles (the ssa decoder OTOH is doing a simple straightforward
          copy). Using the packet timing instead of data string makes sure the
          ass-line now contains the appropriate timing.
      
        - lavc/assenc: just like the ass decoder, the "ssa" encoder is renamed
          into "ssa" (instead of "ass") for consistency with the codec id, and
          allows to add a real "ass" encoder.
      
          One important thing about this encoder is that it only supports one
          ass rectangle: we could have put several dialogue events in the
          AVPacket (separated by a \0 for instance) but this would have cause
          trouble for the muxer which needs not only the start time, but also
          the duration: typically, you have merged events with the same start
          time (stored in the AVPacket->pts) but a different duration. At the
          moment, only the matroska do the merge with the SSA-line codec.
      
          We will need to make sure all the decoders in the future can't add
          more than one rectangle (and only one Dialogue line in it
          obviously).
      
        FORMATS
        -------
      
        - lavf/assenc: the .ass/.ssa muxer can take both SSA and ASS packets.
          In the case of ASS packets as input, it adds the timing based on the
          AVPacket pts and duration, and mux it with "Dialogue:", trailing
          CRLF, etc.
      
        - lavf/assdec: unchanged; it currently still only outputs SSA-lines
          packets.
      
        - lavf/mkv: the demuxer can now output ASS packets without the need of
          any "SSA-lines" reconstruction hack. It will become the default at
          next libavformat bump, and the SSA support will be dropped from the
          demuxer. The muxer can take ASS packets since it's muxed normally,
          and still supports the old SSA packets. All the SSA support and
          hacks in Matroska code will be dropped at next lavf bump.
