• Restream multiple live videos

  8 juin 2020, par re0603

  I have a java application which captures links to streaming videos at different times of the day.

  



  I need to create my own live stream that is always on, and I need to be able to “push” the captured stream links to the channel as and when they become live.

  



  I already have the logic to detect when the streams come on and offline - but what is the best method of creating my own live stream, and programmatically push new streams to the existing channel without having to reconnect to my stream ?

  


• 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))


  


• How to concat videos using ffmpeg ?

  5 septembre 2021, par schissmantics

  I'm trying to concat several videos using ffmpeg on macOS BigSur. I tried :

  


  ffmpeg -i concat:"01-vid.mov|02-vid.mov|03-vid.mov|04-vid.mov" out.mov


  


  which results in only 01-vid.mov being re-encoded for some reason and saved to out.mov.

  


  and :

  


  cat '01-vid.mov' > vid.txt
cat '02-vid.mov' > vid.txt
cat '03-vid.mov' > vid.txt
cat '04-vid.mov' > vid.txt
ffmpeg -f concat -safe 0 -i vid.txt -c copy out.mp4


  


  Which results in the same outcome.

  


  and :

  


  cat 01-vid.mov 02-vid.mov 03-vid.mov 04-vid.mov > out.mov


  


  which results in out.mov having the size of the 4 combined but a duration of only the first one.

  


  and :

  


  I join the vids using quicktime but whenever I try to re-encode the resulting vid using ffmpeg, it produces a corrupt video despite the input seemingly ok.
