  lavc : allow asynchronous decoders to return correct pkt_dts values
  The generic code in utils.c sets the AVFrame.pkt_dts field from the
  
  packet it was supposedly decoded. This does not have to be true for a
  
  fully asynchronous decoder like mmaldec. It could be overwritten with an
  
  incorrect value. Even if the decoder doesn’t determine the DTS (but sets
  
  it to AV_NOPTS_VALUE), it’s impossible to determine a correct value in
  
  utils.c.
  Decoders can now be marked with FF_CODEC_CAP_SETS_PKT_DTS, in which case
  
  utils.c won’t overwrite the field. The decoders are expected to set this
  
  field (even if they only set it to AV_NOPTS_VALUE).

• Errata to correct typo in bark equation in 6.2.5 of spec ; the last

  27 février 2015, par Monty

  Errata to correct typo in bark equation in 6.2.5 of spec ; the last
  paren was misplaced.  The error apparently appeared when resetting the
  doc to XML or DocBook.  Note that lspmap.png was erroneously updated
  to reflect the typo in r8547 and so it's been wrong since then too.
  The original HTML spec was correct (as is the code).
  Also remove the associated rendered versions of the typeset equations
  
  as they're no longer used (and lspmap.png was incorrect as described
  
  above anyway)

• Windows FFmpeg converting imges into a gif with correct framerate

  26 janvier 2016, par Zombie Waffles

  I’ve been using ffmpeg to create animated gif images from images.

  Every time I use this command ;

  ffmpeg.exe -r 120 -f concat -i images.txt ffmpeg.gif

  the output file it produces is way slower than 120 frames per second.

  Is there something I’m missing to set the gif’s fps to 120 instead of 1 ?

  Output #0, gif, to 'ffmpeg.gif':
