      avcodec: export motion vectors in frame side data on demand · b0352b19
      Clément Bœsch authored
      The reasoning behind this addition is that various third party
      applications are interested in getting some motion information out of a
      video "for free" when it is available.
      
      It was considered to export other information as well (such as the intra
      information about the block, or the quantization) but the structure
      might have ended up into a half full-generic, half full of codec
      specific cruft. If more information is necessary, it should either be
      added in the "flags" field of the AVMotionVector structure, or in
      another side-data.
      
      This commit also includes an example exporting them in a CSV stream.

      replaygain: correctly parse peak values · 8542f9c4
      Alessandro Ghedini authored
      According to the ReplayGain spec, the peak amplitude may overflow and may result
      in peak amplitude values greater than 1.0 with psychoacoustically coded audio,
      such as MP3. Fully compliant decoders must allow peak overflows.
      
      Additionally, having peak values in the 0<->UINT32_MAX scale makes it more
      difficult for applications to actually use the peak values (e.g. when
      implementing clipping prevention) since values have to be rescaled down.
      
      This patch corrects the peak parsing by removing the rescaling of the decoded
      values between 0 and UINT32_MAX and the 1.0 upper limit.
