  avcodec/mjpegenc: Don't allocate unnecessarily much memory
  
  We need to allocate space for 64 coefficients per block;
  24dbc4c2e82481f89d6fcacee1949e5038c5c2fc wanted to
  perform the calculation 64*sizeof(MJpegHuffmanCode)
  at compile time, yet in the end did it in a way that
  made it allocate 64 times as much memory as needed.

• avformat/rtpenc : Add flag AVFMT_NODIMENSIONS.

  avformat/rtpenc: Add flag AVFMT_NODIMENSIONS.
  
  Not all rtp formats require the video dimensions to be available
  up front. H264 and HEVC will send them as stream parameters.
  The flag is restrictive and prevents RTP repacketization
  without parsing the codec information out of the stream.
  
  This change checks to see if the codec parameters are available
  on the rtp formats that need it.

  doc/ffmpeg: document videotoolbox in -hwaccel option
  
  Add videotoolbox to the list of supported hardware acceleration methods
  in the -hwaccel option documentation. This option allows users to utilize
  Apple's VideoToolbox framework for hardware-accelerated video decoding
  on macOS and iOS devices.
  
  The videotoolbox acceleration has been supported for a while, but was
  missing from the documentation.

• fftools/cmdutils : fix error message for "ffmpeg -init_hw_device list"

  fftools/cmdutils: fix error message for "ffmpeg -init_hw_device list"
  
  When running 'ffmpeg -init_hw_device list' to display available hardware
  devices, it incorrectly shows an error message:
  "Failed to set value 'list' for option 'init_hw_device': Immediate exit requested"
  
  This is a regression introduced by commit a50f90f1c23. The command is
  actually working as intended - it should exit after listing devices, but
  shouldn't display an error message.

  fate/vcodec: Test non-default b_strategy
  
  With this modification the test would have caught the regression
  introduced in 72bf3d3c12ae562fd408603483bc59058757b1a1.
