const ffmpegPath = require('@ffmpeg-installer/ffmpeg').path;
const ffmpeg = require('fluent-ffmpeg');
ffmpeg.setFfmpegPath(ffmpegPath);
var images = [
  '1.jpg',
  '2.jpg',
]

var videoOptions = {
  fps: 25,
  loop: 5, // seconds
  transition: true,
  transitionDuration: 1, // seconds

• Convert streaming MPEG-4 raw data to H.264

  16 août 2012, par Jonathan Hawkes

  I've got a Sony network camera (SNC-RZ25N) that I am trying desperately to get data from in some meaningful format. The documentation says it sends MPEG-4 raw data, but is not more specific than than. I can capture a segment of the stream using curl ( http://techhead.biz/media/tsv.m4v ) and it will play using VLC and ffplay (though it plays too fast in ffplay).

  After a day and a half of tinkering, I just discovered that I cannot use ffmpeg to convert this stream directly. For one, the only way ffmpeg accepts piped data as input (that I'm aware of) is in the 'yuv4mpegpipe' format.

  I tried piping to ffmpeg using 'm4v' as the specified format, but it seems to want to read the entire stream before it begins processing.

  Anyone know how I can do this ? Using commandline tools ? Open source libraries in ANY programming language ? Simpler solutions are preferred, but any working solution would be great.

• Record audio data to an existing media file using FFMPEG API

  3 février 2021, par bbdd

  My task is to record the received audio data in a media file. I have no problem with this, everything works fine. But, when closing the audio file, I will no longer be able to re-open it and write the audio data to the end of the audio file. How do I solve this problem ? And in general, is it possible to write new data to the end of an existing media file ?

  


  This is a piece of code where I record the trailer and close the media file :

  


  // Writing the stream trailer to an output
// media file and free the file private data.
av_write_trailer(p_oFrmCtx);
avformat_close_input(&p_oFrmCtx);
