• ffmpeg : Unable to find a suitable output format

  30 janvier 2024, par Pdrewicz

  I'm trying to convert .webm into .dfpwm with ffmpeg

  


  ffmpeg -i /download/test.webm -ac 1 -c:a dfpwm /converted/test.dfpwm -ar 48k -y

  


  And I'm getting this error

  Same command works fine on my windows PC but I'm trying to move project to ubuntu server.

  


• Node-JS convert mp4 to m3u8 with FFMPEG : Unable to find a suitable output format for 'v:1,a:1"'

  18 mars 2021, par Jérémy Gachon

  I am writing a server-side function to convert a mp4 file to m3u8, but there is an error with the differents video size. I want to have my video in differents sizes (4k UHD, 2k, 1080p, 720p...) but, with this line : "-var_stream_map", "'v:0,a:0 v:1,a:1'",, there is an error :

  


  


  [NULL @ 0x7fe9de00d800] Unable to find a suitable output format for 'v:1,a:1"'
v:1,a:1" : Invalid argument

  


  


  When I delete this line, all work, but I have just the v0 in 640x360 and not the v1 (960x540).

  


  How can I bypass this error to have all the video sizes ?

• Where can I find high-quality videos for testing video processing ?

  15 novembre 2012, par Workman

  Aside from Big Buck Bunny, Sintel, and Elephant's Dream, what are other high-quality and free sources for high quality video ?

  I'm using these videos internally to test video transcoding options and am not public redistributing. Any suggestions for content that falls under this category ?
