      dnxhddata: Fix 10-bit DNxHD quant matrices · bfe1cd80
      Joseph Artsimovich authored
      Convert them to zigzag order, as the rest of them are.
      
      When I was adding support for 10-bit DNxHD, I just copy-pasted the
      missing quant matrices from the spec. Now it turns out the existing
      matrices in dnxhddata.c were in zigzag order. This resulted in wrong
      quantization for 10-bit DNxHD. The attached patch fixes the problem by
      converting 10-bit quant matrices to zigzag order.

      h261: Signal freeze picture release for intra frames · 02b7c630
      Stian Selnes authored
      Freeze picture release should be set to 1 when we're responding to a
      fast update request. For simplicity we set it for all intra frames,
      including those that starts a GOP.
      
      Fixes issue where Tandberg MXP1700 does not recover from packet loss
      state since it's waiting for the freeze picture relase indication.

      h261: Set 'still image mode off' in picture header · dc1de0b9
      Stian Selnes authored
      Ref H.261 recommendation section 4.2.1.3, setting the still image flag
      to 1 disables still image mode. Some decoders require this in order to
      decode the bitstream as normal video.
      
      Fixes H.261 calls to Cisco E20.
      
      Also, reserved (aka spare) bits should be set to 1 unless specified
      otherwise.

      ljpegenc: deMpegEncContextize · 24abd806
      Anton Khirnov authored
      The encoder uses almost none of the mpegvideo infrastructure, only some
      fields from MpegEncContext.
      
      The FATE results change because now an all-zero quant matrix is written
      into the file. Since it is not used for anything for ljpeg, this should
      not be a problem.

      wmv2: move IDCT to its own DSP context. · e6bc38fd
      Ronald S. Bultje authored
      This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
      other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
      and get corrupt output.
      
      Fate tests for all wmv2-related tests change, because (for some obscure
      reason) they forced use of the MPEG IDCT. You would get the same changes
      previously by not using -idct simple in the fate test (or replacing it
      with -idct auto).
