• Node js async/await promise problem with ytdl and ffmpeg

  31 août 2020, par WorkoutBuddy

  I built a simple youtube downloader cli. It looks like this (without any arg parsing for easier reproduction) :

  


  const ytdl = require('ytdl-core');
const config = require('config');
const progressBar = require('./progressBar');
const logger = require('./logger');
const ffmpeg = require('fluent-ffmpeg');

const url = 'https://www.youtube.com/watch?v=Np8ibIagn3M';

const getInfo = async (url) => {
    logger.info(`Getting metadata for ${url}`);
    const response = await ytdl.getBasicInfo(url);
    const info = response.videoDetails.title;
    logger.info(`Title: ${info}`);
    return info;
};

const getStream = async (url) => {
    logger.info(`Downloading from ${url} ...`);

    let allReceived = false;
    return new Promise((resolve, reject) => {
        const stream = ytdl(url, {
            quality: 'highest',
            filter: (format) => format.container === 'mp4',
        })
            .on('progress', (_, totalDownloaded, total) => {
                if (!allReceived) {
                    progressBar.start(total, 0, {
                        mbTotal: (total / 1024 / 1024).toFixed(2),
                        mbValue: 0,
                    });
                    allReceived = true;
                }
                progressBar.increment();
                progressBar.update(totalDownloaded, {
                    mbValue: (totalDownloaded / 1024 / 1024).toFixed(2),
                });
            })
            .on('end', () => {
                progressBar.stop();
                logger.info('Successfully downloaded the stream!');
            });
        return resolve(stream);
    });
};

const convertToMp3 = async (stream, title) => {
    return new Promise((resolve, reject) => {
        ffmpeg({ source: stream })
            .output(`${config.get('audioDir')}/${title}.mp3`)
            .audioBitrate('192k')
            .run();
        return resolve();
    });
};

const main = async (url) => {
    const info = await getInfo(url);
    console.log('here 1');
    const stream = await getStream(url);
    console.log('here 2');
    await convertToMp3(stream, info);
    console.log('done');
};

main(url);


  


  The output looks like :

  


  ➜ node youtube.js

  However, I would expect this output :

done


  


  I think I have troubles to understand async/await. As far as I understood, promisifying a function allows me wait for the result. However, it seems that it does not work. I do not know why and how to properly debug it.

  


  EDITED :

  


  const getStream = async (url) => {
    logger.info(`Downloading from ${url} ...`);

    let allReceived = false;
    return new Promise((resolve, reject) => {
        const stream = ytdl(url, {
            quality: 'highest',
            filter: (format) => format.container === 'mp4',
        })
            .on('progress', (_, totalDownloaded, total) => {
                console.log('totalDownloaded: ' + totalDownloaded);
                if (!allReceived) {
                    console.log('total: ' + total);
                    progressBar.start(total, 0, {
                        mbTotal: (total / 1024 / 1024).toFixed(2),
                        mbValue: 0,
                    });
                    allReceived = true;
                }
                progressBar.increment();
                progressBar.update(totalDownloaded, {
                    mbValue: (totalDownloaded / 1024 / 1024).toFixed(2),
                });
            })
            .on('end', () => {
                progressBar.stop();
                logger.info('Successfully downloaded the stream!');
                resolve(stream);
            });
    });
};


  


  But now it is like this :

• Very slow writes on MySQL 8 - waiting for handler commit

  23 mai 2023, par Akshat Goel

  I have MySQL 8 docker installation installed on an edge device which has the following two tables to write to

  


  video_paths | CREATE TABLE `video_paths` (
  `entry` int(11) NOT NULL AUTO_INCREMENT,
  `timestamp` bigint(20) NOT NULL,
  `duration` int(11) NOT NULL,
  `path` varchar(255) NOT NULL,
  `motion` int(11) NOT NULL DEFAULT '0',
  `cam_id` varchar(255) NOT NULL DEFAULT '',
  `hd` tinyint(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`entry`),
  KEY `cam_id` (`cam_id`),
  KEY `timestamp` (`timestamp`)
) ENGINE=InnoDB AUTO_INCREMENT=7342309 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci


  


  AND

  


  CREATE TABLE `tracker` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `table_name` varchar(255) NOT NULL,
  `primary_key_name` varchar(255) NOT NULL,
  `pointer` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  UNIQUE KEY `table_name` (`table_name`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci


  


  The following queries are run every few secs for up to 32 cameras and are taking a lot of time as indicated by the slow query log.

  


  UPDATE tracker SET pointer = 7342046 WHERE table_name = 'video_paths'

INSERT INTO video_paths (timestamp,duration,path,cam_id,hd) VALUES (1597548365000,5000,'/s/ss/x-0/v/2020-08-16/3/1.ts','x-1',1)



  


  Most of the time is spent in the waiting for handler commit state

  


  The total size of my data (tables + index) is 1GB and I have the following settings enabled to optimise for write

  


  skip-log-bin - Disabled the bin log because I don't have a replica and therefore no use for it
innodb_flush_log_at_trx_commit =2 - I am Optimising for performance rather than consistency here.
range_optimizer_max_mem_size =0 As mention in this question, I have allowed max memory to range optimiser.
inndo_buffer_pool_size= 512Mb - This should be enough for my data ?.
  
innodb_log_file_size= 96Mb *2 files

  


  I am seeing queries that are taking up to 90-100 secs sometimes.

  


  SET timestamp=1597549337;
INSERT INTO video_paths (timestamp,duration,path,cam_id,hd) VALUES (1597548365000,5000,'/s/ss/x-0/v/2020-08-16/3/1.ts','x-1',1);
# Time: 2020-08-16T03:42:24.533408Z
# Query_time: 96.712976  Lock_time: 0.000033 Rows_sent: 0  Rows_examined: 0


  


  ---UPDATE---
Here's the complete my.cnf file

  


  my.cnf

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

skip-log-bin
innodb_buffer_pool_size=536870912
innodb_log_file_size=100663296

# Custom config should go here
!includedir /etc/mysql/conf.d/

conf.d/docker.cnf 
[mysqld]
skip-host-cache
skip-name-resolve 


  


  The docker container is using the host mode so complete 15GB memory is available to the container.

  


  --- UPDATE 2 ---
After increasing the innodb_buffer_pool_size to 2GB as suggested by @fyrye, the statements have now started getting stuck on STATE = UPDATE instead of waiting for handler commit.

  


  ---- UPDATE 3 ---
Looks like the CPU is causing the bottleneck

• ffmpeg issue when using it from kurento to rtmp stream

  I successfully managed to connect ffmpeg with an RTP endpoint of my kurento server. On many tries before I got a "Connection timed out" due my docker configuration. In my docker logs I see following now after RTP endpoint creation and starting ffmpeg :

  At facebook live it does not receive the video stream. In log I just see this message :

  


  Facebook has not received video signal from the video source for some time. Check that the connectivity between the video source and Facebook is sufficient for the source resolution and bitrate. Check your video encoder logs for details. If problems persist, consider improving connection quality or reducing the bitrate of your video source.

  


  On Kurento Java code I am doing following :

  


  


  1. Create an RTP endpoint

     


  


  2. Connect it with the video source from the user

     


  


  3. Create an SDP offer and save it to a file (currently /tmp/test.sdp)

     


  


  4. Process SDP offer with the RTP endpoint

     


  


  5. Start the ffmpeg process with (net.bramp.ffmpeg.builder.FFmpegBuilder) :

     


     FFmpegBuilder builder = new FFmpegBuilder()
.addExtraArgs("-protocol_whitelist", "file,http,https,tcp,tls,udp,rtp")
.addExtraArgs("-rtbufsize", "1500M")
.addExtraArgs("-re")
.setInput("/tmp/test.sdp")
.addOutput(rtmpURL)
.setFormat("flv")
.addExtraArgs("-bufsize", "4000k")
.addExtraArgs("-maxrate", "1000k")
.setAudioCodec("libmp3lame")
.setAudioSampleRate(FFmpeg.AUDIO_SAMPLE_44100)
.setAudioBitRate(1_000_000)
.addExtraArgs("-profile:v", "baseline")
.setVideoCodec("libx264")
.setVideoPixelFormat("yuv420p")
.setVideoResolution(width, height)
.setVideoBitRate(1_000_000)
.setVideoFrameRate(20)
.addExtraArgs("-deinterlace")
.addExtraArgs("-preset", "medium")
.addExtraArgs("-g", "60")
.addExtraArgs("-r", "30")
.done();

FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
executor.createJob(builder).run();



     


  


  


  Can somebody guide here on this issue ? Thanks in advance

  


  EDIT 01 : I disabled now

  


  // FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
// executor.createJob(builder).run();


  


  so that ffmpeg does not start automatically. After java created the test.sdp, I ran ffmpeg by myself in the console not to stream to facebook but to a mp4 :

  


  ffmpeg -loglevel debug -protocol_whitelist file,crypto,udp,rtp -re -vcodec libvpx -acodec opus -i /tmp/test.sdp -vcodec libx264 -acodec aac -y output.mp4

  


  The output looks as following - I interrupted it after 25s with CTRL + C

  


  root@app:/var/www# ffmpeg -loglevel debug -protocol_whitelist file,crypto,udp,rtp -re -vcodec libvpx -acodec opus -i /tmp/test.sdp -vcodec libx264 -acodec aac -y output.mp4
