FFMPEG : merging multiple audio (MP3) and single image convert them into a video [on hold]
9 décembre 2013, par user3027136I'm tired of searching for this problem. I have found 2 solutions here, but both work only partially.
What I want to do is to convert all the MP3 inside a folder (if possible subfolders, too) to avi or anything else accepted by Youtube. I have created 2 .bat that should do this (according to the other threads here). They don't, one of them creates the avi without the image (black) and the other seems to capture the screen.
Here they are.
If you know about ffmpeg please point me to the right direction. Thank you.This one uses mp3info.exe - to be honest I have no idea what mp3info does, I just guess it finds the lenght of the song to be mathed later with the length of the video.
@echo off
for %%a in (*.mp3) do (
for /f "delims=" %%b in ('mp3info.exe -p %%S "%%a"') do (
ffmpeg -i "%%a" -loop 1 -r 1 -i "cover.jpg" -acodec copy "%%~na.mp4" -t %%b
)
)This seems more simple, runs faster but captures the screenshot and ignores the cover.jpg file.
@echo off
for %%A IN (*.mp3) DO ffmpeg -i "%%A" -i "cover.jpg" "%%A.mpg"
donemp2info.exe, cover.jpeg and the .bat scripts are in the same folder with the .mp3 files.

Creating a continuous stream for RTMP in Node.js
9 mars 2023, par hankthetank27I'm working on an app that downloads audio from youtube that will be streamed sequentially, similar to radio broadcast. I'm having trouble getting the individual tracks to stream continuously. My idea was to write the tracks sequentially into a readable stream that then is read by FFMPEG. Here is the code I'm having trouble with...


import ytdl from "ytdl-core";
import ffmpeg from 'fluent-ffmpeg';
import { Readable } from "node:stream"

export async function startAudioStream(): Promise<void>{

 const mainStream = await createStreamedQueue()

 ffmpeg(mainStream)
 .inputOptions([
 '-re'
 ])
 .outputOption([
 // '-c:v libx264',
 // '-preset veryfast',
 // '-tune zerolatency',
 '-c:a aac',
 '-ar 44100',
 ])
 .save('rtmp://localhost/live/main.flv');
};

async function createStreamedQueue(): Promise<readable>{

 function createStream(): Readable{
 const stream = new Readable({
 read(){},
 highWaterMark: 1024 * 512,
 });
 stream._destroy = () => { stream.destroyed = true };
 return stream;
 }

 const mainStream = createStream();

 const ref1 = 'https://youtu.be/lLCEUpIg8rE'
 const ref2 = 'https://youtu.be/bRdyzdXJ0KA';

 function queueSong(src: string, stream: Readable): Promise<void>{
 return new Promise<void>((resolve, reject) => {
 ytdl(src, {
 filter: 'audioonly',
 quality: 'highestaudio'
 })
 .on('data', (data) => {
 stream.push(data);
 })
 .on('end', () => {
 resolve();
 })
 .on('error', (err) => {
 console.error('Error downloading file from YouTube.', err);
 reject(err);
 })
 })
 }
 
 await queueSong(ref1, mainStream);
 // console.log('after firsrt: ', mainStream)
 await queueSong(ref2, mainStream);
 // console.log('after second: ', mainStream)
 return mainStream;
};
</void></void></readable></void>

To start,
startAudioStreamis called to initiate a readable stream of audio to an RTMP server via FFMPEG. That is working fine. The part I'm having trouble with is "queuing" the tracks into the stream that's being fed into FFMPEG. Right now, I have a "main" stream that each songs data is being pushed into, as you can see inqueueSong. At the end of ytdl stream, the promise is resolved, allowing for the next song to be queued and its data to be pushed intomainStream. The issue that I'm experiencing is that the audio fromref1is only every played.

I can see in the logs that
mainStreamdoes grow in length after each call toqueueSong, but still will only stream the audio from the first track. My initial thought was that there is a terminating character at the of the last data chunk thats being written to the steam for each song ? But maybe im getting screwed up on how streams work...

using default poster image with video and audio tags
23 décembre 2016, par Ravinder PayalI have a web-application where users can share music and videos ( will be saved on sme-server utilized by Web-Application ) and as we know some audio /video files have posters/thumbnails included/attached with them.
NOW, I want to show those posters with audio or video in HTML5.
I know about poster tag, but it needs a separate image file to show. However, I want to show image file attached with song (audio / video).
Any suggestion related anyjava-scriptor HTML api will be appreciated.
I know about obtaining poster images withff-mpeg(or similar libraries), but that will add an extra work load on my server. Thanks.Note :-I may consider any server side efficient solution alo.
Thanks in advance.
