• OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error

  19 avril, par user2262504

  I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.

  



  It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec 'libx264'" error.

  



  Anyone has ideas to solve this problem ?

  



  More specifically :

  



  

  1. anyone knows where and how OpenCV invoke ffmpeg API ?

  


  2. how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?

  


  3. will changes of default in ffmpeg be carried to libx264 ?

  


  



  Errors :

• ffmpeg says : "option framerate not found"

  29 novembre 2018, par Jason

  Good afternoon.

  I’ve been trying to use ffmpeg to split a .mpeg into a sequence of .jpeg images. Please note that this is the inverse problem of the one specified here, but the problem I’m facing is not the same as the problem the author of that thread is facing.

  Specifically, I have tried all the following mpeg codecs available in my ffmpeg installation :

  DEV D  ffv1            FFmpeg video codec #1
  
  DEVSD  ffvhuff         Huffyuv FFmpeg variant
  
  DEVSDT mpeg1video      MPEG-1 video
  
  D V DT mpeg1video_vdpau MPEG-1 video (VDPAU acceleration)
  
  D V D  mpeg2_crystalhd MPEG-2 Video (CrystalHD acceleration)
  
  DEVSDT mpeg2video      MPEG-2 video
  
  DEVSDT mpeg4           MPEG-4 part 2
  
  D V D  mpeg4_crystalhd MPEG-4 Part 2 (CrystalHD acceleration)
  
  D V DT mpeg4_vdpau     MPEG-4 part 2 (VDPAU)
  
  D VSDT mpegvideo       MPEG-1 video
  
  D V DT mpegvideo_vdpau MPEG-1/2 video (VDPAU acceleration)
  
  D VSDT mpegvideo_xvmc  MPEG-1/2 video XvMC (X-Video Motion Compensation)
  
  DEVSD  msmpeg4         MPEG-4 part 2 Microsoft variant version 3
  
  D V D  msmpeg4_crystalhd MPEG-4 Part 2 Microsoft variant version 3 (CrystalHD acceleration)
  
  D VSD  msmpeg4v1       MPEG-4 part 2 Microsoft variant version 1
  
  DEVSD  msmpeg4v2       MPEG-4 part 2 Microsoft variant version 2

  I’ve tried supplying ffmpeg with all different codecs to try to split an input .mpeg video file with 2548 frames into 2548 .jpegs, by using the -vcodec option :

  ffmpeg -r 2548 -i frames.mpeg frames_%06d.jpg -vcodec $codec

  where $codec is any codec among the ones listed above, e.g. ffv1, mpeg4, etc. However, all my efforts result in the following error :

  [NULL @ 0x1948f20] Value 4707126720094797824.000000 for parameter 'probesize' out of range

  Option framerate not found.  

  Which is weird, because I’ve actually specified the frame rate parameter through the -r switch. I googled a bit and it appears that this error was mentioned approximately a year and a half ago on the ffmpeg bug tracker but that information makes little sense to me because it’s relevant to the devs. Curiously, if I interchange the position of the parameters and put -r after -i or even after -vcodec, the error message changes to :

  frames.mpeg: could not find codec parameters

  I’m at a loss as to what to do with this problem, and am looking for some assistance.

  Kind regards,

• ffmpeg convert to webm error "too many invisible frames"

  24 janvier 2019, par Вадим Коломиец

  I need to convert any format (for example, mp4, avi etc) to .webm with own ioContext. I build ffmpeg with vpx, ogg, vorbis, opus and create simple project. But when i write any frame i get error "Too many invisible frames. Failed to send packet to filter vp9_superframe for stream 0"

  I’ve already tried convert from webm to webm with copy codec params with avcodec_parameters_copy and this works.
