• How to convert a script from youtube-dl

  16 janvier 2020, par danilshik

  There is a bash/batch file script :

  ffmpeg -i `youtube-dl https://www.twitch.tv/zero` -vf fps=fps=60, scale=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time 60 test.mp4

  The script is not mine, but it allows you to record video with a constant frame rate of parts. Unfortunately in cmd it does not work for me. Already tried everything, I do not know what the error is.

  I am getting No such file or directory.

  Tried 'youtube-dl https://www.twitch.tv/zero', the same error

  I tried "youtube-dl https://www.twitch.tv/zero", error : youtube-dl https://www.twitch.tv/zero: Invalid argument

  What am I doing wrong ? The author assures that he works on linux

  Update

  I tried ffmpeg -i $ (youtube-dl -f best -g https://www.twitch.tv/zero) .... The same error

  Update 2

  Why the video size exceeds 500 Mb ? What am I doing wrong ?

  
  

  Code

  cls && @echo off & setlocal enableextensions enabledelayedexpansion 
  
  set "_tag_00=https://www.twitch.tv/avagg"
  
  set "_tag_01=--ignore-errors --abort-on-error --ignore-config --flat-playlist --geo-bypass "
  
  set "_tag_02=--restrict-filenames --no-part --no-cache-dir --write-thumbnail --prefer-ffmpeg "
  
  set "_tag_03=--ffmpeg-location .\ --postprocessor-args  -i "%%(title)s.%%(ext)s" -vf fps^=fps^=60^,"
  
  set "_tag_04=scale^=1920x1080 -c:v libx264 -b:v 500k -preset superfast -c:a copy -f segment -segment_time "
  
  set "_tag_05=60 %%^(title^)s.mp4"
  
  
  
  youtube-dl "!_tag_00!" -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" -o "%%^(title^)s.%%^(ext^)s" !_tag_1!!_tag_2!!_tag_3!!_tag_4!!_tag_5!

• How to generate valid live DASH for YouTube ?

  24 septembre 2019, par Matt Hensley

  I am attempting to implement YouTube live video ingestion via DASH as documented at :
  https://developers.google.com/youtube/v3/live/guides/encoding-with-dash

  To start, I am exercising the YouTube API manually and running ffmpeg to verify required video parameters before implementing in my app.

  Created a new livestream with liveStreams.insert and these values for the cdn field :

  "cdn": {
  
      "frameRate": "variable",
  
      "ingestionType": "dash",
  
      "resolution": "variable"
  
  }

  Created a broadcast via liveBroadcasts.insert, then used liveBroadcasts.bind to bind the stream to the broadcast.

  Then I grabbed the ingestionInfo from the stream and ran this ffmpeg command, copying in the ingestionAddress with the streamName :

  ffmpeg -stream_loop -1 -re -i mov_bbb.mp4 \
  
      -loglevel warning \
  
      -r 30 \
  
      -g 60 \
  
      -keyint_min 60 \
  
      -force_key_frames "expr:eq(mod(n,60),0)" \
  
      -quality realtime \
  
      -map v:0 \
  
      -c:v libx264 \
  
      -b:v:0 800k \
  
      -map a:0 \
  
      -c:a aac \
  
      -b:a 128k \
  
      -strict -2 \
  
      -f dash \
  
      -streaming 1 \
  
      -seg_duration 2 \
  
      -use_timeline 0 \
  
      -use_template 1 \
  
      -window_size 5 \
  
      -extra_window_size 10 \
  
      -index_correction 1 \
  
      -adaptation_sets "id=0,streams=v id=1,streams=a" \
  
      -dash_segment_type mp4 \
  
      -method PUT \
  
      -http_persistent 1 \
  
      -init_seg_name "dash_upload?cid=${streamName}&copy=0&file=init$RepresentationID$.mp4" \
  
      -media_seg_name "dash_upload?cid=${streamName}&copy=0&file=media$RepresentationID$$Number$.mp4" \
  
      'https://a.upload.youtube.com/dash_upload?cid=${streamName}&copy=0&file=dash.mpd'

  It appears all the playlist updates and video segments upload fine to YouTube - ffmpeg does not report any errors. However the liveStream status always shows noData, and the YouTube Live Control Room doesn’t show the stream as receiving data.

  The DASH output, when written to files play backs fine in this test player. The playlist output doesn’t match exactly the samples, but does have the required tags per the "MPD Contents" section in the documentation.

  Are my ffmpeg arguments incorrect, or does YouTube have additional playlist format requirements that are not documented ?
