• Why does this HEVC HLS stream not play on browsers ?

  22 janvier 2024, par Sebastian

  I have a HEVC HLS stream that does not play when I paste it e.g. in Safari. The video is encoded in HEVC and has a resolution of 4608x1728. The screen just stays black.

  


  The URL is : https://cdn2.taggy.cam/videos/JFNi2a3JVxmUxWh8t6YkbzR5t9HyS94ZaQy81KVrbwJ2ztTp9f/hls/h265/video.m3u8

  


  (or https://cdn2.taggy.cam/videos/JFNi2a3JVxmUxWh8t6YkbzR5t9HyS94ZaQy81KVrbwJ2ztTp9f/hls/h265/playlist.m3u8 for the master playlist)

  


  VLC player does play it.

  


  I tried several different players to get an error message, but the only thing I got was "MEDIA.VIDEO_ERROR (4,,CHUNK_DEMUXER_ERROR_APPEND_FAILED : Video stream codec hevc doesn't match SourceBuffer codecs.)"

  


  The video is initially created with FFMpeg by recording the RTSP stream of a webcam with

  


  ffmpeg -i rtsp://stream -tag:v hvc1 -f hls -hls_time 1 -hls_list_size 0 -hls_segment_filename output-directory/video-%05d.m4s -c copy


  


  Any ideas how to debug this would be appreciated !

  


  Thanks,
Sebastian

  Im coding a discord bot, i installed ytdl and ffmpeg, both correctly (cmd shows version), but it quite dont plays the yt links, this is the code :
  } else if (message.content.startsWith ===$prefixplay`)
  const ytdl = require(’ytdl-core’) ;
  const streamOptions =
  seek : 0,
  volume : 1
   ;
  const broadcast = bot.createVoiceBroadcast() ;
  var link = arg1

      bot.voiceChannel.join()
  
          .then(connection => {
  
              const stream = ytdl(arg1, {
  
                  filter: 'audioonly'
  
              });
  
              broadcast.playStream(stream);
  
              const dispatcher = connection.playBroadcast(broadcast);
  
          })
  
          .catch(console.error);

• Split video stream with FFmpeg and play part with FFplay [closed]

  22 mars 2024, par Jan Hein

  I have a video stream send with FFmpeg to a other computer on my local network.
At the receiver computer I want to split the video stream in multiple parts and play them at the receiver computer. How can I do that ?

  


  Example :
Stream send form sender to receiver is 1000x1000 pixels.
At the receiver split the 1000x1000 pixel stream into four parts of 500x500 pixels, and play them all four on the receiver in a separate player.

  


  I have tryed it with a multicast stream to the receiver, and played it four times with FFplay, but that was not working correct.

  


  I also hve looked for multiple outputs with FFmpeg and then multiple pipes to FFplay, but could not find a solution.
