      media: add filters · ea2933d4
      Philippe Gorley authored
      Adds dependency to libavfilter, which provides many useful utilities
      such as hardware encoding, mixing audio or rotating video.
      
      Access to libavfilter is done through the MediaFilter class, which takes
      a filter graph string and AVFrames as input and outputs filtered
      AVFrames.
      
      Adds unit tests for MediaFilter.

      media: update ffmpeg io read callbacks · 78ed2663
      Philippe Gorley authored
      In newer versions, AVIOContext's read_packet cb no longer considers 0
      as being EOF. Changes the read callbacks for SDP and RTP to return
      AVERROR_EOF instead of 0.

      video: increase default h264 level · 1e5a3092
      Philippe Gorley authored
      Level 2.0 (0x14) can only handle up to 352x288 at 30 fps, which can trip
      up the decoder (especially a hardware decoder) if the video is of a
      higher resolution. Increase the default level to 4.1 (0x29), which can
      handle up to 2,048x1,024 at 30 fps.

      some devices are providing their framerate ratios in a format
      incompatible with FFmpeg encoder.

      coreaudio: implement audiolayer for iOS · 7fa8fc41
      Andreas Traczyk authored
      - Seperates coreaudio implementations for iOS and OS X.
      - Manages input/ouput port overrides when layer is reset via calls
        to Dring::setAudioOutputDevice in response to an audio route override
        event listened for by the iOS client.
      - TODO: use AVAudioSession API with graphs in Objective-C++, or
        optimally, in Swift in the iOS/OS X clients.

      accel: refactor and speed up fallback · ecf3e901
      Philippe Gorley authored
      Falling back from hardware to software decoding requires only a
      reinitialization of the AVCodecContext. Hardware decoding failure is no
      longer bubbled up to the RTP session, which makes it much faster.

      accel: refactor to fit new hwaccel api · ea8c5921
      Philippe Gorley authored
      libavutil now covers the simple cases for creating and managing devices.
      As Ring does not need to fine-tune these processes, most of the accel
      code can be and has been removed.
      
      Most hardware decoders output NV12, so skip extra conversions by
      outputting NV12. Said pixel format is supported by everything that isn't
      excessively old.

      encoder: use max 16 threads for video, 4 for audio · d08826f0
      Adrien Béraud authored
      Audio encoding is usually mono-threaded and doesn't require
      as much CPU as video encoding. Limit to 4 threads since more
      would not be useful and might introduce latency and decrease performance.
      
      Video encoding takes significantly more resources, however for live encoding,
      using more than 16 threads might introduce unreasonable latency.
      Since new customer CPUs (AMD Ryzen and Intel Core i7/i9) now have
      more than 16 logical cores, setting a higher bound of 16 threads.

      decoder: limit number of threads · c2c6ddc0
      Adrien Béraud authored
      Using too many threads for decoding is not recommended and can
      introduce latency.
      Also during a call there are 2 live encoding and 2 live decoding,
      so using all threads for every decoding is not useful and could
      decrease performance and increase latency because of more
      CPU context switch.
      This is especially visible on machines with many logical cores
      like AMD Threadrippers or some Intel CPUs.
      Ideally, loads should use in total as many threads as logical cores
      to profit from the full machine power while limiting context switches.
      
      In this patch, decoders will use half the number of logical core,
      with a maximum of 8 threads.
