• Convert MP4 File to M3U8(only m3u8 file No ts file) [closed]

  28 février 2024, par Ayan Ansari

  I'm a beginner working on a content streaming app (like Netflix) where i want to add feature of quality control of the content (like switch to 480p, 720p, 1080p etc). I'm using Exoplayer for video player and the app is almost ready. But the problem i've been facing is that all the files are either mp4, mkv etc file but i need m3u8 file. So I tried converting video using FFmpeg tools which worked but it gives me LOTS OF TS file which i need to upload along with the m3u8 file. After doing some more research i was able to reduce it to 1 m3u8 and 1 TS file. Is it possible to Create only 1 m3u8 file no TS file ? Here are what i've tried.

  


  ffmpeg -i input.mp4 -c:a aac -strict -2 -c:v libx264 -preset ultrafast -crf 28 -maxrate 2M -bufsize 4M
-hls_time 6 -hls_playlist_type vod -hls_flags single_file -f hls output.m3u8


  


  I also thought i will upload all the video in different quality manually, but as a broke 17 Y/O teenager, noobie who don't know how to use AWS or cloud Servers and also AWS or Google Cloud doesn't accept Indian Debit Card(Rupay) for free trial.
Please also suggest some where i can store these data for free i guess( i don't care about where i upload, i just need the link which i can put in my database.)
Thank You :)

  


• node.js - Error : ENOENT : no such file or directory, unlink

  10 août 2020, par necroface

  I have the function below to convert a .wav file to .mp3. As you can see, before using the ffmpeg module to convert the audio file, I already check if the file exists or not, then upon conversion, I only keep the new file and delete the old one. But occasionally the console throws me the error Error: ENOENT: no such file or directory, unlink, which means that I unlink (delete) a non-existing file. I cannot understand why, because I already have an existence check even before the conversion, so it is supposed to have existed to be unlinked.

  



  module.exports.convertAndMoveElastic = async (calllog) => {
    let { start, sip_uri, direction, source, destination } = calllog;
    const VNtimezoneOffset = 7 + new Date().getTimezoneOffset() / 60;
    const startTime = new Date(start + VNtimezoneOffset * 3600000 - 60000);
    const date = startTime.getDate() < 10 ? `0${startTime.getDate().toString()}` : startTime.getDate().toString();
    const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
    const month = months[startTime.getMonth()];
    const year = startTime.getFullYear().toString();
    sip_uri = sip_uri || (direction === 'outgoing' ? source : destination);
    const [extension, domain_name] = sip_uri.split("@");
    return new Promise(async (resolve, reject) => {
        const links = await getLinkWithElastic(calllog);
        if (!links) { return reject(); }
        let file_id, filepath;
        for (let link of links) {
            const { callid, sipCallid, uuid, record_path } = link._source;
            if (record_path) {
                let recordPathArr = record_path.split('/');
                file_id = recordPathArr[recordPathArr.length - 1].split('.')[0];
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (!file_id || !fs.existsSync(filepath)) {
                file_id = callid;
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (!file_id || !fs.existsSync(filepath)) {
                file_id = uuid;
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (fs.existsSync(filepath)) { break; }
        }
        if (!fs.existsSync(filepath)) { return reject(); }
        ffmpeg(filepath)
            .audioCodec('libmp3lame')
            .on('error', function (error) {
                reject(error);
            })
            .on('end', function () {
                resolve({ recordUrl: `${host}/record/download/${file_id}.mp3` });
                fs.unlinkSync(filepath);
            })
            .toFormat('mp3')
            .saveToFile(path.resolve(dest_directory, file_id + ".mp3"));
    });
};


  


• FFMPEG not supporting emoji text

  23 décembre 2019, par walt3rwhite

  I need to add text that can contain emoji icons over an image. I need to implement this thing in JavaScript. I am thinking to use FFMPEG bash commands. However, it just displays square boxes.
