      gstavviddec: Limit default number of decoder threads · 970c83ea
      Alicia Boya García authored and GStreamer Marge Bot's avatar GStreamer Marge Bot committed
      When the `max-threads` property is not specified, GStreamer defaults to
      the amount of CPU threads in the system.
      
      The number of threads used in avdec has a direct impact on the latency
      of the decoder, which is of as many frames as threads. Therefore, big
      numbers of threads can make latency levels that can be problematic in
      some applications.
      
      For this reason, ffmpeg emits a warning when more than 16 threads are
      requested.
      
      This patch limits the default number of threads to 16. This affects only
      computers with more than 16 CPU threads when using avviddec without
      setting `max-threads`.

      avviddec: Enforce allocate new AVFrame per input frame · 2e829662
      Seungha Yang authored and Tim-Philipp Müller's avatar Tim-Philipp Müller committed
      ... if ffmpeg would reuse the allocated AVBuffer. Reused AVFrame by
      the ffmpeg seems to break our decoding flow since the reused AVFrame
      holds the initial opaque data (GstVideoCodecFrame in this case), so
      we couldn't trace the our in/out frames.
      To enforce get_buffer() call per output frame, hold another reference
      to the AVBuffer in order to mark the AVBuffer as not writable.
      
      Fixes: gstreamer/gst-libav#62

      docs: don't include the type hierarchy · 6f720ceb
      Ross Burton authored
      gtk-doc can't generate a type hierarchy when scanning gst-libav, and gtk-doc
      1.30 onwards doesn't write a file if there is no type hierarchy (unlike previous
      releases, which wrote an empty file).  This results in the build failing with
      gtk-doc 1.30 onwards, so remove the type hierarchy section from the
      documentation as it doesn't serve any purpose.
      
      Fixes gstreamer/gst-libav#57

      gstav: Use libavcodec util function for version check · 41b2b73c
      Yeongjin Jeong authored and Tim-Philipp Müller's avatar Tim-Philipp Müller committed
      The version of libavutil is printed in the log instead of libavcodec
      because avutil_version() returns LIBAVUTIL_VERSION_INT. This can be confusing,
      so we should be replace it with avcodec_version().

      avauddec: fix decoding of APE and Cook audio · ef8a1bdd
      Tim-Philipp Müller authored
      .. and other formats where ffmpeg gives us multiple
      subframes per input frame.
      
      Since we now support non-interleaved audio, we can't
      just concat buffers any more. Also, audio metas won't
      be combined when buffers are merged, so when we push
      out the combined buffer we'll look at the meta describing
      only the first subframe and think it covers the whole
      frame leading to stutter/gaps in the output.
      
      We could fix this by copying the output data into a new
      buffer when we merge buffers, but that's suboptimal, so
      let's add some API to GstAudioDecoder to push out subframes
      and use that instead.
