• ffmpeg - transcode stream to play on flowplayer [on hold]

  7 janvier 2016, par arlind

  i have a streaming link and im restreaming it via ffmpeg

  -vcodec copy -c:a libmp3lame -ab 48k -ar 22050

  so if i play in flowplayer (web PLayer) i just listen audio perfect and video has problems
  "so i just see images instand of video" its slow and it block

  When i play that video on vlc is working perfect and in video codec i see

    H264 - MPEG-4 AVC (avc1)     MPEG Audyo layer 3 (mp3)

  so how to convert this stream so i can watch on web players like flowplayer or jw player

• Converting avi to mp4 ffmpeg

  26 octobre 2013, par Dirk Swarz

  I use php code :

  $ffmpeg_command ="ffmpeg -i ".$new_name." -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 ".$anew_name;

  $convert_avi = true ;

  i know that the problem is in here :

  -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5

  Idea is when video is converted i can watch it via flash player and now flash player is saying that video is not found or bad syntax so obviuos its bad syntax but i dont know how to fix it

• ffmpeg no such file or directory with wsl2 [closed]

  i want to convert video using ffmpeg and youtube-dl in wsl2.

  


  Im using this command :

  


  ffmpeg -ss 0:0:18 -to 0:1:30 -i "$(youtube-dl -f 18 --get-url 'https://www.youtube.com/watch\?v\=D4gs1nKnO-o')" -c:v copy -c:a copy ~/output_video.mp4


  


  And it produces output as below :

  


  /mnt/d/repos/xyz$ ffmpeg -ss 0:0:18 -to 0:1:30 -i "$(youtube-dl -f 18 --get-url 'https://www.youtube.com/watch\?v\=D4gs1nKnO-o')" -c:v copy -c:a copy /mnt/d/repos/xyz/output_video.mp4
