• 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.

  


• react vite ffmpeg how to resolve worker module returning 404

  27 août, 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(

• How to manage hls in Nginx RTMP module

  27 mars, par syrkandonut

  I would like to manage the hls broadcast on request, like stop/start or some other way in Nginx RMTP module.
My rtmp server needs to support many cameras, however, when it does ffmpeg exec for 200-300 rtmp streams, this is very difficult for the processor, so I would like to execute the ffmpeg command in parallel only on request, how could this be done ?

  


  Rtmp Server

  


  rtmp {
    server {
        listen 1935;
        chunk_size 8192;

        application live {
            live on;
            record off;
            drop_idle_publisher 10s;
            allow publish all;

            on_publish rtmp-router:8082/on_publish;

              exec ffmpeg -i rtmp://localhost:1935/live/$name
              -f lavfi -i anullsrc -c:v copy -c:a aac -shortest -f flv rtmp://localhost:1935/hls/$name_main;
        }


        application hls {
            live on;
            hls on;
            hls_fragment_naming system;
            hls_fragment 2;
            hls_playlist_length 4;
            hls_path /opt/data/hls;
            hls_nested on;

            hls_variant _main BANDWIDTH=878000,RESOLUTION=640x360;
        }
    }
}


  


  I would like to solve this through nginx or python itself, since the server running with threads is written in FastAPI.
