• Revision 3c42657207 : Checking scale factors on access. It is possible to have invalid scale factors

  23 août 2013, par Dmitry Kovalev

  Changed Paths :
   Modify /vp9/common/vp9_reconinter.c

  
   Modify /vp9/common/vp9_scale.c

  
   Modify /vp9/common/vp9_scale.h

   Modify /vp9/encoder/vp9_temporal_filter.c

  
  
  Checking scale factors on access.

  It is possible to have invalid scale factors and not access them
  during decoding. Error is reported if we really try to use invalid scale
  factors.

• avcodec/opustab : Avoid indirection to access ff_celt_window

  3 octobre 2022, par Andreas Rheinhardt

  avcodec/opustab : Avoid indirection to access ff_celt_window
  Currently, it is accessed via a pointer (ff_celt_window)
  
  exported from opustab.h which points inside a static array
  
  (ff_celt_window_padded) in opustab.h. Instead export
  
  ff_celt_window_padded directly and make opustab.h
  
  a static const pointer pointing inside ff_celt_window_padded.
  
  Also mark all the declarations in opustab.h as hidden,
  
  so that the compiler knows that ff_celt_window has a fixed
  
  offset from the code even when compiling position-independent
  
  code.

• FFMpegWriter() [Error 5] Access Denied

  8 juin 2016, par Guillermo

  So, I’m trying to save animations with the animation.save command. I installed ffmpeg in Windows 10 by placing a folder with its binaries in my drive C :\, I have also set the path in my system variables like C :\ffmpeg\bin, and finally, my code for the animation function saving looks like this

   if save=='True':
  
       mywriter = animation.FFMpegWriter()
  
       plt.rcParams['animation.ffmpeg_path'] = 'C:/ffmpeg/bin' 
  
       ani.save('mymovie.avi',writer=mywriter,fps=30)

  and all other kind of variants such as :

      mpl.animation.ffmpeg_path = r'C:\ffmpeg\bin' 
  
      mpl.animation.ffmpeg_path = 'C:\\ffmpeg\\bin' 

  No matter what I do, the result is always :

  File "<stdin>", line 2, in <module>
  
  File "Plot.py", line 168, in animate
  
  ani.save('mymovie.avi',writer=mywriter,fps=30)
  
  File "c:\users\guillermo\appdata\local\enthought\canopy\user\lib\site-packages\matplotlib\animation.py", line 801, in save
  
  with writer.saving(self._fig, filename, dpi):

  return self.gen.next()

  Any ideas ? :D

  It worked perfectly when using :

  plt.rcParams['animation.ffmpeg_path'] = 'C:\\ffmpeg\\bin\\ffmpeg.exe'
