• Getting "Cannot find ffprobe error " when attempting to run nodejs script

  26 février 2020, par Farid Hajnal

  I am attempting to use an npm package for splitting audio (https://github.com/calufornia/audio-split), however I am not able to run a single test since I get the following error on my callback :
  Error : Cannot find ffprobe, I have read a bit and it seems that this is directly related to the npm package fluent_ffmpeg, which is actually a dependency of the first package I mentioned.

  The problem on some other questions/forums is that people do not have properly installed ffmpeg on their environment. In my case however, I have made sure that my PATH is updated with the ffmpeg directory (C :\FFmpeg\bin for me), and I am able to open a command prompt and run both

  ffmpeg -version

  and

  ffprobe -version

  I would much appreciate if anyone else has struggled with this previously and could provide me with some more guidance. Thanks

• Process GIF using FFmpeg libraries - can't find parser at av_parser_init

  24 novembre 2018, par natario

  I am playing with ffmpeg libs, namely libswscale and libavcodec for now. My goal is resize GIF files. From my ridiculous understanding, I think I need to

  • decode the GIF and get an AVFrame
  • process the frame with libswscale
  • encode again into GIF

  But I am stuck at step 1. Based on official sample at https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/decode_video.c , I need to get a parser :

  codec = avcodec_find_decoder(AV_CODEC_ID_GIF);
  
  parser = av_parser_init(codec->id);

  But no parser is found. I am not touching parser in my configure call, so I take all :

  Enabled parsers:

  What am I doing wrong ? If this is the wrong approach, what is the correct one ?
