• react vite ffmpeg how to resolve worker module returning 404

  19 novembre 2024, par pmkob

  I have imported the js, wasm, and worker modules into my project
https://unpkg.com/@ffmpeg/core@0.12.6/dist/esm/ffmpeg-core.js

  


  https://unpkg.com/@ffmpeg/core@0.12.6/dist/esm/ffmpeg-core.wasm
https://unpkg.com/@ffmpeg/core-mt@0.12.2/dist/esm/ffmpeg-core.worker.js

  


  and upon calling the function that the load is in, i get the error in the worker module
Request URL :
http://localhost:3000/node_modules/.vite/deps/worker.js?worker_file&type=module Status Code :
404 Not Found
Referrer Policy :
strict-origin-when-cross-origin

  


  In order to resolve this issue i have added these to my config and looked at similar issues with different threads https://github.com/ffmpegwasm/ffmpeg.wasm/issues/532
but with no luck. The load also never completes.

  


  CONFIG:
export default defineConfig(({ mode }) => ({
//other config stuff
  plugins: [react()],
  optimizeDeps: {
    exclude: ["@ffmpeg/ffmpeg", "@ffmpeg/util"]
  },
  server: {
    headers: {
      "Cross-Origin-Opener-Policy": "same-origin",
      "Cross-Origin-Embedder-Policy": "require-corp"
    }
  }
}));

FILE:
import { FFmpeg } from "@ffmpeg/ffmpeg";
import { fetchFile, toBlobURL } from "@ffmpeg/util";
 const ffmpeg = new FFmpeg();
    await ffmpeg.load({
      coreURL: await toBlobURL(
        `${importedURL}/ffmpeg/ffmpeg-core.js`,
        "text/javascript"
      ),
      wasmURL: await toBlobURL(
        `${importedURL}/ffmpeg/ffmpeg-core.wasm`,
        "application/wasm"
      ),
      workerURL: await toBlobURL(
        `${importedURL}/ffmpeg/ffmpeg-core.worker.js`,
        "text/javascript"
      )
    });


  


• Distributing a Python module with ffmpeg dependency

  17 août 2024, par arafasse

  I’m working on a Python module that harnesses some functionality from the FFmpeg framework - specifically, the ebur128 filter function. Ideally the module will stand on its own as an independent, platform agnostic tool for verifying that audio clips comply with EBU loudness standards. It’s designed so that end users need only perform one simple, (hopefully !) painless installation procedure, which will encompass the installation of both the FFmpeg libraries and my Python wrapper/GUI.

  


  Does anyone have general advice for creating Python module with external dependencies, or specific advice for standardizing the FFmpeg installation across platforms ? Distutils seems pretty helpful – are there other guidelines or standard practices for developing a neatly packaged Python tool ? I want to minimize any installation headaches for end users.

  


• Nginx RTMP module not creating .m3u8 in correct format

  24 juin 2024, par Moiz Hassan

  I am creating a rtmp server using nginx-rtmp-module inside a docker container. Using OBS I can connect with the server to start a live stream. M3U8 and .ts files are being created successfully but the .m3u8 file isn't in format I want. The generated .m3u8 file is like :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:5
#EXT-X-TARGETDURATION:10


  


  but I want to generate .m3u8 file so it is simialr to this :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:10.000000,
0.ts
#EXTINF:10.000000,
1.ts
#EXTINF:10.000000,
2.ts
#EXTINF:10.000000,
3.ts
#EXTINF:10.000000,
4.ts
#EXTINF:10.000000,
5.ts



  


  . The following is the nginx config that I am using :
