• FFmpeg and QuickTime Player dimensions of video do not match [duplicate]

  31 mai 2020, par GRS

  I have a video.mp4, which I scaled using FFmpeg to get out.mp4. The new video has the following probe :

  I am expecting my video player to say the video is 886 x 1920, however, it is 3413:1920.


  



  What could be the error ? I am using pix_frmt=yuva420p and codec=libx264 to create the video.

  



  The error is that my ascpect ratio remains 16:9, which is the original input video, when it should automatically change to 9:19. E.g. 3413 = 1920 * 16 / 9. So why isn't the ascpect ratio changed when the video is scaled ?

• exec.Command not formating input correctly ?

  20 mai 2016, par nadermx

  I’m having a bizzar issue. I have a ffmpeg I run as a subprocess

      ffmpeg = exec.Command("nice", "-n", "10",
  
              "ffmpeg",
  
              "-http_proxy", RandomProxyAddress(),
  
              "-i", fmt.Sprintf(`%s`, vi.GetUrl()),
  
              "-acodec", "libmp3lame",
  
              "-metadata", fmt.Sprintf(`title=%s`, vi.GetTitle()),
  
              "-b:a", fmt.Sprintf("%s", vi.GetAudioQuality()),
  
              "-threads", "0",
  
              "-f", "mp3",
  
              "-")

  But when I run this command I get

  Server returned 403 Forbidden (access denied)

  but when I run the command outside of go it functions correctly.

  ffmpeg -http_proxy http://user:user@123.123.123.123:29842 -i 'https://r5---sn-uqx2-aphl.googlevideo.com/videoplayback?fexp=9405981%2C9414672%2C9416126%2C9416891%2C9422342%2C9422596%2C9423965%2C9425077%2C9428398%2C9431012%2C9432564%2C9433096%2C9433946%2C9434085%2C9435697%2C9435736%2C9435876%2C9437285%2C9437344&clen=3716608&itag=140&ipbits=0&upn=QpGXy0IIxmU&key=yt6&expire=1463728239&id=o-AIlDlUBTmu9UXu0yMp77VXR502YekQi98e6JpvbSzjo0&ms=au&gcr=pe&mv=m&source=youtube&mm=31&mn=sn-uqx2-aphl&pl=24&requiressl=yes&ip=190.234.105.134&mime=audio%2Fmp4&mt=1463706418&sparams=clen%2Cdur%2Cgcr%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cupn%2Cexpire&lmt=1458211566542818&gir=yes&keepalive=yes&sver=3&dur=233.964&initcwndbps=563750&signature=53A8732F8841FC6AC6D6737B35B4EF6FC000F2F0.59E11FB2D3DF96F4C00CE8D84C28D3A546E04F78&ratebypass=yes' -acodec 'libmp3lame' -metadata 'title=This awesome song' -b:a '128k' -threads '0' -f 'mp3' test.mp3

  Does it have something to do with my string formatting or quotations in the exec.Command ?
