• Can't load MPEG file with MSE

  11 juillet 2019, par Léandre

  Here is my problem : I want to reproduce this example of MSE use, but when I change the mp4 file, it doesn’t work. I have this error :

  Failed to execute 'endOfStream' on 'MediaSource': The MediaSource's readyState is not 'open'. at SourceBuffer.<anonymous></anonymous>

  I saw here that I needed to fragment my mp4 file, wich I did. Here is my mp4 file header :

  [ftyp] size=8+28
  
     major_brand = mp42
  
     minor_version = 0
  
     compatible_brand = isom
  
     compatible_brand = iso2
  
     compatible_brand = avc1
  
     compatible_brand = mp41
  
     compatible_brand = mp42
  
  [moov] size=8+3841
  
     [mvhd] size=12+96

  And this is the mp4 file header of the file demo : (this file works)

  [ftyp] size=8+20
  
     major_brand = mp42
  
     minor_version = 1
  
     compatible_brand = mp42
  
     compatible_brand = avc1
  
     compatible_brand = iso5
  
  [moov] size=8+1871
  
     [mvhd] size=12+96
  
        timescale = 1000
  
        duration = 60095 

  Even when I change the minor value with MP4Box -brand mp42:1 fragmented-video.mp4, it doesn’t work.

  I also tried to separate video data and audio data ( view in FFMPEG H.264 encoding for HTML5 (and ultimately MPEG-DASH) ), but it didn’t solve the problem.

  (I tried on Chromium)

  If you have any ideas to solve this, it will be great !

  Thanks

• Manifest error pops up when trying to download certain videos for discord.py music bot

  30 novembre 2020, par bork

  I'm trying to make a discord music bot. I'm using youtube-dl to retrieve the info and ffmpeg to play the audio out. My bot has no problems downloading videos and everything is working fine. But when I tried downloading certain videos, this error popped up :

  


  [dash @ 0x7fe45a801200] Manifest too large: 65055
https://manifest.googlevideo.com/api/manifest/dash/expire/1606336104/ei/CGq-X4G6Htauz7sPrZuCsA8/ip/14.192.212.39/id/64a943d43b8f53eb/source/youtube/requiressl/yes/playback_host/r5---sn-h5mpn-30ae.googlevideo.com/mh/Go/mm/31%2C29/mn/sn-h5mpn-30ae%2Csn-30a7rn7l/ms/au%2Crdu/mv/m/mvi/5/pl/24/hfr/all/as/fmp4_audio_clear%2Cwebm_audio_clear%2Cwebm2_audio_clear%2Cfmp4_sd_hd_clear%2Cwebm2_sd_hd_clear/initcwndbps/533750/vprv/1/mt/1606314038/fvip/5/keepalive/yes/beids/23927369/itag/0/sparams/expire%2Cei%2Cip%2Cid%2Csource%2Crequiressl%2Chfr%2Cas%2Cvprv%2Citag/sig/AOq0QJ8wRQIhAOn6Br0QsuXc-3unfhYdzXVXcydzVWioIQlKvv2U4i3OAiB6ApoiqFoPvE3YKYGPbRiId_bHQYO8zsawGGPMidYGAA%3D%3D/lsparams/playback_host%2Cmh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps/lsig/AG3C_xAwRQIhANmxfRNBI4wSJo6trsKkq8GinQ-ADMxgHRmelBwM-GEAAiAafey9YRrZz1h1S6PzV3u0S6IsZUKscGrrGP9Pofv2uQ%3D%3D: Invalid data found when processing input


  


  After trying to download other videos, which have no problem at all, I found out that the videos showing these errors have an extra step that downloads MPD manifest. I would try to download videos that are way larger and it would work, but it's just these certain videos, with the duration of about 7-10 minutes, that would have these errors. I'm really lost.

  


  This is my code for playing the videos in the voice channels :

  


  voice = get(client.voice_clients, guild = ctx.guild)
with YoutubeDL(ydl_opts) as ydl:
                info = ydl.extract_info(url[playlist], download = False)

URL = info['formats'][0]['url']
voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS))


  


• Options for replacing RTMP for live streaming

  22 décembre 2016, par molokoV

  I have a backend streaming video to web browsers using RTMP. On the browsers we use jwplayer.
  As everybody know flash player is going to be deprecated soon.
  Im looking for options to modify the backend using another streaming solution.

  We have made some test using DASH but it has too much delay for live streamining compared to RTMP.

  What are the options for anyone using RTMP ?
