      ff_put_wav_header: add flag to force WAVEFORMATEX · 5e7d21c7
      Daniel Verkamp authored
      Partially undoes commit 2c4e08d8:
      
          riff: always generate a proper WAVEFORMATEX structure in
          ff_put_wav_header
      
      A new flag, FF_PUT_WAV_HEADER_FORCE_WAVEFORMATEX, is added to force the
      use of WAVEFORMATEX rather than PCMWAVEFORMAT even for PCM codecs.
      
      This flag is used in the Matroska muxer (the cause of the original
      change) and in the ASF muxer, because the specifications for
      these formats indicate explicitly that WAVEFORMATEX should be used.
      
      Muxers for other formats will return to the original behavior of writing
      PCMWAVEFORMAT when writing a header for raw PCM.
      
      In particular, this causes raw PCM in WAV to generate the canonical
      44-byte header expected by some tools.

      adpcmenc: Calculate the IMA_QT predictor without overflow · aa264da5
      Michael Niedermayer authored
      Previously, the value given to put_bits was 10 bits long for positive
      predictors, even though 9 bits were to be written. The extra bit could
      in some cases overwrite existing bits in the bitstream writer cache.
      
      This fixes a failed assert in put_bits.h, when running a version
      built with -DDEBUG.
      
      The fate test result gets slightly improved, thanks to getting rid
      of the overwritten bits in the bitstream writer cache.
