      accel: skip main memory when hardware reencoding · 52fbc755
      Philippe Gorley authored
      If the video input is being decoded on the hardware, use the hardware
      frames directly when encoding. Skips the transfer back to software in
      the video sender and the transfer to hardware in the encoder.
      
      Falls back to using the main memory as a middle man if the link between
      encoder and decoder fails.

      encoder: lazy initialize video stream · dfdee183
      Philippe Gorley authored
      Sets up video streams upon receiving the first video frame. Audio
      streams are still initialized as soon as possible.
      
      This allows a video encoder to use the pixel format of its received
      frames, and to set up a hardware transcoding pipeline if it receives
      a hardware frame.

      accel: add hardware encoding · 12932733
      Philippe Gorley authored
      Adds VAAPI and VideoToolbox hardware encoders.
      
      Abstracts hardware related field accesses from the encoder and decoder
      to put them in HardwareAccel. They are freed in ~HardwareAccel.
      
      Limits bitrate when hardware encoding h264, else it can easily go up to
      a few MiB/s.

      encoder: cleanup and simplify · e059062a
      Philippe Gorley authored
      Cleans up the encoder a bit and removes methods that weren't used or did
      nothing. In any case, it should not be the encoder's responsibility to
      mute audio/video.
      
      Removes direct accesses to private data. All these options are accessible
      through the av_opt_* API with the AV_OPT_SEARCH_CHILDREN flag.
      
      Adding streams to the encoder is now done separately than opening an RTP
      output in an effort to streamline the encoder setup (file vs RTP).

      Recorder has multiple streams, and needs to know which streams it's

      encoder: support loading per encoder config · 19442e3b
      Philippe Gorley authored
      This allows users to use different configurations than the one provided
      by Jami. File settings overwrite Jami's existing configuration options.
      
      Note that only codec-level options are supported, format-level is not
      implemented.
      
      The following options are ignored, as they are set by going into the
      settings page: width, height, framerate, sample_rate, channels,
      frame_size, parameters (internal option for h264's profile level id).
      
      If a file encoder.json exists in the same folder as dring.yml, it is
      loaded into the encoder's configuration options. The config file is
      separated by codec. Multiple configurations can exist for the same codec
      family (ex: libx264 and h264_vaapi) because each encoder has different
      options. Section name should be the codec implementation's name and not
      the codec's name (h264 won't work, but libx264 will).
      
      Example configuration file:
      {
          "libx264": {
              "crf": 15,
              "preset": "ultrafast"
          },
          "h264_vaapi": {
              "low_power": 1
          },
          "libopus": {
              "application": "voip"
          }
      }

      encoder: make resolution even · db6c3ddf
      Philippe Gorley authored
      An even width/height is required by at least x264. This is especially
      for image and gif streaming, as video usually already has an even
      width/height.

      encoder: add error checking to videoFrameSize · c499a22b
      Jinbo Li authored
      av_image_get_buffer_size can return a negative error code. Prevents
      casting such an error to a large positive integer that may cause a
      bad_alloc exception on the subsequent buffer allocation.

      media: simplify timestamp computation · d36d4d6e
      Philippe Gorley authored
      Audio time bases are always the inverse of the sample rate, meaning the
      increment is always the number of samples in a frame. Video usually has
      a time base inverse of its framerate, but this is not always the case.

      audiobuffer: add conversion to AVFrame · e6ed1e1f
      Philippe Gorley authored
      Moves the AudioBuffer to AVFrame conversion logic outside of the
      MediaEncoder, so the latter only deals with AVFrame.
      
      Does not copy the buffer, the resulting AVFrame will simply point to the
      existing buffer.
      
      This is the first in a series of patches attempting to rid Ring of its
      RingBuffer/RingBufferPool system.

      recorder: refactor pipeline · 11585ed2
      Philippe Gorley authored
      Moves the recorder up one level to the VideoInput, VideoReceiveThread
      and AudioReceiveThread, instead of the MediaDecoder (there's no
      equivalent to the VideoInput in the audio layer).
      
      Emits the RecordPlaybackStopped when the recording is stopped, so the
      client can sync its recording state with the daemon, in case the daemon
      stops recording by itself (rather than user intervention).

      Sets decoder framerate during stream setup.
      Scales decoder timestamps from container time base to codec time base.
      Substracts stream start time from timestamp in decoder.
      Fixes MediaStream to use AVCodecContext instead of AVStream.
      Encoders gets next timestamp using AVCodecContext instead of AVStream.

      encoder: merge common encoding code · 43f22d20
      Philippe Gorley authored
      Refactors out the common code from video and audio encoding/flushing
      into a single method. This reuses code instead of duplicating it.
      
      The method is public in the hopes of being able to reuse MediaEncoder
      elsewhere in the codebase.
      
      Allow caller to specify the stream index for the future case that the
      AVFormatContext contains multiple streams (recording video and audio).
