  libavcodec/mips/h264dsp_msa.c : fix type in some function parameters
  This fixes a build problem for MIPS architecture that looks like this :
  libavcodec/mips/h264dsp_msa.c:2498:6 : error : conflicting types for
  
  ‘ff_weight_h264_pixels16_8_msa’
  
   void ff_weight_h264_pixels16_8_msa(uint8_t *src, int stride,
  This bug was introduced by commit bc26fe89275c267d169b468356c82ee59874407d :
    avcodec/h264 : Use ptrdiff_t for (bi)weight functions
  That commit changed the data type of some function parameters in some
  
  function definitions. However, the implementation of those functions in
  
  libavcodec/mips/h264dsp_msa.c wasn’t changed accordingly.

• convert MOV to mp4 using transcode

  3 janvier 2017, par koem

  I want to convert a MOV from my Casio cam to mp4 using transcode. Why transcode ? Because I also want to deshake the video in the same step.

  When I use

  ffmpeg -i in.MOV out.mp4

  it works. When using

  transcode -J stabilize -i in.MOV

  or

  transcode -J transform -i in.MOV -y ffmpeg -F mpeg4 -o out.mp4

  I get hundreds of these errors :

  [ffmpeg_audio] Error: avcodec_open2 failed
  
  [adpcm_ima_wav @ 0x1f7f180] Only 4-bit ADPCM IMA WAV files are supported

  This looks to me as if transcode uses ffmpeg internally.

  I could use ffmpeg to make it mp4 first and then use transcode to stabilize the video, but then it would be re-encoded twice which I would like to avoid.

  This is what mplayer says about my MOV file :

  How can I make it work with transcode without using ffmpeg first ?
