      Fix encoder debug setting · 87c40b35
      Johann Koenig authored
      Propagate debug setting to the EBML struct. When writing the application
      name, this allows us to strip the version code and keep the output
      metadata static.

      vpxenc: fix time and fps calculation in 2-pass encoding · aabae97e
      Yunqing Wang authored
      When we do 2-pass encoding, elapsed time is accumulated through
      whole 2-pass process, which gives incorrect time and fps results
      for second pass. This change fixed that by resetting the time
      accumulator for second pass.

      Packing bitstream on-the-fly with delayed context updates · 52cf4dca
      Attila Nagy authored
      Produce the token partitions on-the-fly, while processing each MB.
      Context is updated at the beginning of each frame based on the
      previoud frame's counters. Optimally encoder outputs partitions in
      separate buffers. For frame based output, partitions are concatenated
      internally.
      
      Limitations:
          - enabled just in combination with realtime-only mode
          - number of encoding threads has to be equal or less than the
          number of token partitions. For this reason, by default the encoder
          will do 8 token partitions.
          - vpxenc supports partition output (-P) just in combination with
          IVF output format (--ivf)
      
      Performance:
          - Realtime encoder can be up to 13% faster (ARM) depending on the number
          of threads and bitrate settings. Constant gain over the 5-16 speed
          range.
          - Token buffer reduced from one frame to 8 MBs
      
      Quality:
          - quality is affected by the delayed context updates. This again
          dependents on input material, speed and bitrate settings. For VC
          style input the loss seen is up to 0.2dB. If error-resilient=2
          mode is used than the effect of this change is negligible.
      
      Example:
      ./configure --enable-realtime-only --enable-onthefly-bitpacking
      ./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480
      --target-bitrate=1000 --token-parts=3 --static-thresh=2000
      --ivf -P -t 4 -o strm.ivf tanya_640x480.yuv

      Remove the frame rate factor for key frame size. · 507ee87e
      Marco Paniconi authored
      When temporal layers is used (i.e., number_of_layers > 1),
      we don't use the frame rate boost for setting the key
      frame target size. The factor was forcing the target size to be
      always at its minimum (2* per_frame_bandwidth) for low frame rates
      (i.e., base layer frame rate).
      
      Generally we should modify or remove this frame rate factor;
      for now we turn if off for number_of_layers > 1.
