• Error : [Error : ENOENT : no such file or directory, open './1695556319341.mp3']

  24 septembre 2023, par James

  I'm trying to convert an mp4 file to an mp3 file and then directly upload it to Firebase storage without saving it locally in my machine, How can I do that currently I'm getting an error when I try to do that the error is "Error : [Error : ENOENT : no such file or directory, open './1695556319341.mp3']" How can i fix this issue with my Node.js code and make things work ?

  


  import { initializeApp } from "firebase/app";
import { getStorage, ref, getDownloadURL, uploadBytesResumable } from "firebase/storage";
import serviceAccount from '../firebase/serviceAccountKey';
import { path as ffmpegPath } from '@ffmpeg-installer/ffmpeg';
import ffmpeg from 'fluent-ffmpeg';
import { readFile, unlink } from 'fs/promises';

initializeApp(serviceAccount);
ffmpeg.setFfmpegPath(ffmpegPath);

async function convertMP4ToMP3AndUploadToFirebase(inputPath: any, firebaseStoragePath: any) {
    const date = Date.now();
    const outputPath = `./${date}.mp3`;

    try {
        await ffmpeg(inputPath)
            .output(outputPath)
            .audioCodec('libmp3lame')
            .format('mp3')
            .run();

        const storage = getStorage();
        const storageRef = ref(storage, firebaseStoragePath);

        const fileBuffer = await readFile(outputPath);
        const metadata = { contentType: 'audio/mpeg' };
        const uploadTask = uploadBytesResumable(storageRef, fileBuffer, metadata);
        const snapshot = await uploadTask;
        const downloadURL = await getDownloadURL(snapshot.ref);
        await unlink(outputPath);

        console.log('MP4 file converted to MP3 and uploaded to Firebase Storage successfully!');
        console.log('Download URL:', downloadURL);
    } catch (error) {
        console.error('Error:', error);
    }
}

const inputPath = './video.mp4';
const date = Date.now();
const firebaseStoragePath = `./${date}.mp3`;

convertMP4ToMP3AndUploadToFirebase(inputPath, firebaseStoragePath);


  


• ffmpeg and libaom compilation failed "unable to open include file `third_party/x86inc/x86inc.asm"

  7 octobre 2023, par sam

  I'm trying to build ffmpeg using this guide :
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

  


  the problem is when i try to compile libaom using the following commands :

  


  cd ~/ffmpeg_sources && \
git -C aom pull 2> /dev/null || git clone --depth 1 https://aomedia.googlesource.com/aom && \
mkdir -p aom_build && \
cd aom_build && \
PATH="$HOME/bin:$PATH" cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_TESTS=OFF -DENABLE_NASM=on ../aom && \
PATH="$HOME/bin:$PATH" make && \
make install


  


  i get the following error :

  


  /root/ffmpeg_sources/aom/aom_dsp/x86/sad4d_sse2.asm:14: fatal: unable to open include file `third_party/x86inc/x86inc.asm'

  Is there any fix for this issue ?

  


• Could not open codec 'libopenh264' : Unspecified error

  15 novembre 2023, par Gingerbread

  I am using OpenCV to process videos for my research. I have Python 2.7 and OpenCV 3.2 versions installed on Windows 10. When I do background subtraction on a video in Python using OpenCV, it works fine and produces the output. However, when I try to save the background subtracted video, it throws this error :

  



  warning: Error opening file (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:779)
warning: MAH00119.avi (/build/opencv/modules/videoio/src/cap_ffmpeg_impl.hpp:780)
OpenCV: FFMPEG: tag 0x34363258/'X264' is not supported with codec id 28 and format 'h264 / raw H.264 video'

Failed to load OpenH264 library: openh264-1.6.0-win64msvc.dll
    Please check environment and/or download library: https://github.com/cisco/openh264/releases

[libopenh264 @ 0000000001f5bf60] Incorrect library version loaded
Could not open codec 'libopenh264': Unspecified error


  



  I am processing MP4 videos. And I followed the instructions carefully while installing ffmpeg, like adding the bin's path to environment variables. I don't know what else to do. Stuck on this for three days now.

  



  Any help would be much appreciated !
Thanks in advance !!
