• Revision 198fa6d0a0 : Add Neon horizontal and vertical vp9_mbloop_filter - The vp9 mbfilter C code wi

  1er juillet 2013, par Frank Galligan

  Changed Paths :
   Modify /vp9/common/arm/neon/vp9_loopfilter_neon.asm

  
   Modify /vp9/common/vp9_rtcd_defs.sh

  
  
  Add Neon horizontal and vertical vp9_mbloop_filter

   The vp9 mbfilter C code will branch on flat and mask. This CL
  will perform both branches and combine the data. A later CL will
  perform a check to see if all patch will take one branch.
   These functions are about 1.75 times faster than the C code on
  Nexus 7.

  PS #3
   Changed all functions to dub limit, blimit, and thresh from
  vld dx[], freeing up r4-r6.
   Changed code to use vbif to reduce one instruction and free
  up a d register.

  swresample/rematrix : fix typo in clean_layout()
  av_channel_layout_index_from_channel() takes an AVChannel value, not a mask.

• MoviePy, using a gif as an ImageClip ?

  13 avril 2018, par Slake

  Using a gif inside an ImageClip doesn’t work, is it a normal behavior ?

  The code

  #!/usr/bin/env python
  
  from moviepy.editor import *
  
  
  
  video = VideoFileClip('./video.mp4')
  
  watermark = (ImageClip("./my.gif")
  
                          .set_duration(10))
  
  
  
  watermaked = CompositeVideoClip([video, watermark], size=video.size)
  
  watermaked.write_videofile('./gif_output.mp4', fps=30, threads=1)

  .

  The error

  ValueError: could not broadcast input array from shape (150,150) into shape (150,150,3)

  .

  The stack error
