• FFMPEG width not divisible by 2 (639x360)

  5 octobre 2020, par yasgur99

  I am using python wrapper command of ffmepeg. I followed the tutorial from here for a "Production ready HLS" : https://docs.peer5.com/guides/production-ready-hls-vod/

  


  This is my code :

  


   subprocess.call(['ffmpeg', '-y', '-i', download_path,
                     '-vf', 'scale=w=640:h=360:force_original_aspect_ratio=decrease', \
                     '-c:a', 'aac', '-ar', '48000', '-c:v', 'h264', \
                     '-profile:v', 'main', '-crf', '20', '-sc_threshold', '0', \
                     '-g', '48', '-keyint_min', '48', '-hls_time', '4', \
                     '-hls_playlist_type', 'vod',  '-b:v', '800k', \
                     '-maxrate', '856k', '-bufsize', '1200k', '-b:a', '96k', \
                     '-hls_segment_filename', upload_path + \
                     '/360p_%03d.ts', upload_path + '/360p.m3u8', \
                     '-vf', 'scale=w=842:h=480:force_original_aspect_ratio=decrease', \
                     '-c:a', 'aac', '-ar', '48000', '-c:v', 'h264', \
                     '-profile:v', 'main', '-crf', '20', '-sc_threshold', '0', \
                     '-g', '48', '-keyint_min', '48', '-hls_time', '4', \
                     '-hls_playlist_type', 'vod', '-b:v', '1400k', \
                     '-maxrate', '1498k', '-bufsize', '2100k', '-b:a', '128k', \
                     '-hls_segment_filename', upload_path + \
                     '/480p_%03d.ts', upload_path + '/480p.m3u8', \
                     '-vf', 'scale=w=1280:h=720:force_original_aspect_ratio=decrease', \
                     '-c:a', 'aac', '-ar', '48000', '-c:v', 'h264', \
                     '-profile:v', 'main', '-crf', '20', '-sc_threshold', '0', \
                     '-g', '48', '-keyint_min', '48', '-hls_time', '4', \
                     '-hls_playlist_type', 'vod', '-b:v', '2800k', \
                     '-maxrate', '2996k', '-bufsize', '4200k', '-b:a', '128k', \
                     '-hls_segment_filename', upload_path + \
                     '/720p_%03d.ts', upload_path + '/720p.m3u8', \
                     '-vf', 'scale=w=1920:h=1080:force_original_aspect_ratio=decrease', \
                     '-c:a', 'aac', '-ar', '48000', '-c:v', 'h264', \
                     '-profile:v', 'main', '-crf', '20', '-sc_threshold', '0', \
                     '-g', '48', '-keyint_min', '48', '-hls_time', '4', \

                     '-maxrate', '5350k', '-bufsize', '7500k', '-b:a', '192k', \
                     '-hls_segment_filename', upload_path + '/1080p_%03d.ts', upload_path + '/1080p.m3u8'])


  


  And getting this output

  


  [libx264 @ 0x7fb95500c800] width not divisible by 2 (639x360)
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


  


  Any ideas of whats going wrong ?

  


• Discord.js Music bot "TypeError" when playing audio with dispatcher

  21 février 2020, par Cole Perry

  I’m new to Discord.js and I’m trying to have the bot join a voice channel and play an audio file on my computer. I have been following this guide : https://discord.js.org/#/docs/main/stable/topics/voice . Here is the Index.js page :

  Colesbot.on('message', message=>{
  
      if (message.content === '/join') {
  
          // Only try to join the sender's voice channel if they are in one themselves
  
          if (message.member.voiceChannel) {
  
              message.member.voiceChannel.join().then(connection => {
  
                  message.reply('I have successfully connected to the channel!');
  
  
  
                  // To play a file, we need to give an absolute path to it
  
                  const dispatcher = connection.playFile('C:\Users\bobal\Documents\GitHub\Spotify-Playlist-Discord-bot\Assets\Glory.mp3');
  
  
  
                  dispatcher.on('end', () => {
  
                      // The song has finished
  
                      console.log('Finished playing!');
  
                    });
  
  
  
                  dispatcher.on('error', e => {
  
                      // Catch any errors that may arise
  
                      console.log(e);
  
                    });
  
  
  
                    dispatcher.setVolume(0.5); // Set the volume to 50%
  
              }).catch(console.log);
  
      } else {
  
          message.reply('You need to join a voice channel first!');
  
        }
  
      }
  
   });
  
  exports.run = (client, message, args) => {
  
      let user = message.mentions.users.first || message.author;
  
  }

  FFMPEG is installed and I have set the environment path for it. When I type FFMPEG in the command line I get the proper response.

  Some have said I need to install the ffmpeg binaries but when I run npm install ffmpeg-binaries I get an error message that is here

  So then I tried installing an older version and I’m now using ffmpeg-binaries@3.2.2-3 but when I type /join I get the error

  [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

• php-fpm freeze user session on ffmpeg exec

  21 janvier 2014, par aya

  I'm have some problem with php-fpm and ffmpeg.

  If i'm launching encoding from php just with simple exec, then for this certain user who initiate encoding all other php responses seems like a frozen(timeout or ignored). So for this user site becomes fully unresponsable.

  If i'm launching encoding from php but with "&" on the end of command, then all comes fine, encoding still eats cpu but site fully responsible for user.

  So maybe there is some docs or info about this behavior so i'm can get why it work this way, so where exactly it gets stuck.

  Thank you
