• How to buffer videojs so preload won't show ?

  9 septembre 2015, par toy

  I’m building video cutting tool using videojs. In order to give the feedback to user right away instead of using ffmpeg to merge the video right away. I just swap the videos instead. However, during the swapping you would see the loading icon when the second video is being loaded. Is there any tricks that would tell videojs to load the video before so when the video plays it would just play right away.

• ffprobe returning video stream data twice

  15 novembre 2015, par GeorgeKat

  I’m trying to return specific values from ffprobe :

  ffprobe -v error -select_streams V:0 -show_entries stream=index,width,height,sample_aspect_ratio,display_aspect_ratio:format=duration  -of default=noprint_wrappers=1:nokey=1 test.MTS

  The stream values in the output are repeated :

  0
  
  1920
  
  1080
  
  1:1
  
  16:9
  
  0
  
  1920
  
  1080
  
  1:1
  
  16:9
  
  116.640000

  The format value is not repeated.
  If I strip the printer values to see what’s going on :

  ffprobe -v error -select_streams V:0 -show_entries stream=index,width,height,sample_aspect_ratio,display_aspect_ratio:format=duration  test.MTS

  I see a section called [PROGRAM] with stream 0 repeated within it :

  [PROGRAM]
  
  [STREAM]
  
  index=0
  
  width=1920
  
  height=1080
  
  sample_aspect_ratio=1:1
  
  display_aspect_ratio=16:9
  
  [/STREAM]
  
  [/PROGRAM]
  
  [STREAM]
  
  index=0
  
  width=1920
  
  height=1080
  
  sample_aspect_ratio=1:1
  
  display_aspect_ratio=16:9
  
  [/STREAM]
  
  [FORMAT]
  
  duration=116.640000
  
  [/FORMAT]

  Can someone please help me to return only the video stream 0 values once ?
