• NodeJs - How can i use ffmpeg with createReadStream (make a post with file in memory)

  11 mars 2023, par Matheus Gomes

  This is my code :

  


  import fs from 'fs';
import ffmpeg from 'fluent-ffmpeg';
import ffmpegPath from '@ffmpeg-installer/ffmpeg';
import { Configuration, OpenAIApi } from 'openai';

const configuration = new Configuration({ apiKey: 'sk-XXX' });
const openai = new OpenAIApi(configuration);

ffmpeg.setFfmpegPath(ffmpegPath.path);

(async () => {
  try {
    const track = 'https://tempstorage.com/file.ogg';// your path to source file

    ffmpeg(track)
      .toFormat('mpeg')
      .save('test.mpeg')
      .on('end', async () => {
        const resp = await openai.createTranscription(
          fs.createReadStream('test.mpeg'),
          'whisper-1',
        );
        console.log(resp); // FINAL
      });
  } catch (error) {
    console.log(error);
  }
})();


  


  I need to do the same thing, but instead of saving the file locally, I want to keep it in memory and use it without saving anything locally. I couldn't figure out how to do it. Can anyone point me in the right direction ?

• What options are available for speeding up video load times on a webpage when video is hosted on IPFS

  10 août 2022, par Ryan D

  I have a site that pulls videos hosted on IPFS (Interplanetary File System), most of the videos load and play fine but if a user doesn't have a strong internet connection or if a larger video, it constantly buffer's and play's choppy.

  


  Since the video isn't hosted on my server i'm not sure what options I have to help speed the load times up. The original video is uploaded to my site though and I pass it to IPFS to upload directly. I don't currently download it to my server first to speed up the uploading process, or so the user doesn't need to wait for a double upload.

  


  I know youTube has a compression algorithm and does something with chopping up the video into chunks or something but i'm not sure exactly how that works. Im not very experienced with video codec and encoding. Ive heard good things about FFmpeg but not sure if that would help my current situation.

  


  Any ideas or tools I should look into that may help me out would be appreciated. For larger videos I could download to my server first if theres a compression mechanism or something I could apply first to help the overall load times of the site although not ideal for the user uploading.

  


  Im using videoJS for my video player with preload set to auto if that helps at all.

  


  <video width="320" height="240" controls="controls" class="video-js video" poster="{Image URL}">&#xA;    <source src="{IPFS URL}" type="video/mp4">&#xA;</source></video>&#xA;

  


  Options im currently using

  


  Load the video after the DOM has loaded to not slow down page loads

  


  Preload the video

  


  


  


  Although I don't think that does much.

  


  Other than that I don't know what else I can do. Im good with PHP and or Javascript to handle this task if theres something I should look into.

  


  Thanks !
