  • Passing long url as string in python subprocess

    16 février 2015, par rogoro

    When I pass this long url as

     subprocess.Popen(["ffmpeg", "-i",
    
 "https://r6---sn-ufuxaxjvh-q4fe.googlevideo.com/videoplayback?pl=16&upn=1-Ch_dUO4YE&ipbits=0&requiressl=yes&sver=3&itag=22&ratebypass=yes&dur=86.053&source=youtube&sparams=dur%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Cmime%2Cmm%2Cms%2Cmv%2Cpl%2Cratebypass%2Crequiressl%2Csource%2Cupn%2Cexpire&key=yt5&mime=video%2Fmp4&fexp=900805%2C907263%2C919150%2C927622%2C942901%2C943917%2C945089%2C947225%2C948124%2C948603%2C952302%2C952605%2C952612%2C952901%2C955301%2C957201%2C959701&expire=1424133614&id=o-ANRJvkk7EYBC4ug2L1u_aJ9BifNGN5wrOnqvWkhce-WT&mm=31&initcwndbps=5045000&signature=5DC013D85BE81A4EFFA9C7B9510865A5BB7E2121.3655C01D8075EAB4668D4AFB28C401896038470A&ip=137.144.99.102&ms=au&mv=m&mt=1424111820", "out.mp4"], stdout=subprocess.PIPE)

    It works.

    But It doesn’t when I pass it as variable.
    Example :

      link =
    
  "the_above_long_string"
    

    
 subprocess.Popen(["ffmpeg", "-i", link, "out.mp4"], stdout=subprocess.PIPE) // NOT WORKING

    Any idea how to make it work ?

  • vlc 2.1.5 cannot find libavutil under ffmpeg

    22 février 2015, par micr0sub

    The distro I’m using (CentOS 6.6) doesn’t have a high enough version of VLC in yum that I’ve found (>=2.1.0) for the project I’m working on, so I’m trying to build it from source. After finding out that the version of ffmpeg in the repositories is also not high enough (see https://www.bountysource.com/issues/173789-build-process-is-busted-in-vdpau) I’ve built ffmpeg from source as well. Now that’s finished, I get :

      libswresample   1.  1.100 /  1.  1.100

    However, when I run ./configure under VLC I get the following message :

    No package 'libavutil' found. Pass --disable-avcodec to ignore this error.

    Does anyone know why this is happening ?

    Thanks.

  • ffmpeg error : "Missing ')' or too many args in 'if(gt(a,1),650,-1)'"

    23 février 2015, par Remini me

    I am trying to run this ffmpeg command in linux shell, to scale down the video (if portrait, than to maximum height of 650, while adjusting the width. And if landscape, then 650 maximum width, and adjust the height with aspect ratio) :

    ffmpeg -i 1.mp4 -r 30 -vf scale="'if(gt(a,1),650,-1)':'if(gt(a,1),-1,650)'" -vcodec libx264 output_file1.mp4

    But I get the following error :

    [scale @ 0x1d48a40] [Eval @ 0x7fff53a49340] Missing ’)’ or too many
    args in ’if(gt(a,1),650,-1)’ [scale @ 0x1d48a40] [Eval @

    Error when evaluating the expression ’if(gt(a,1),-1,650)’

    **EDIT : I have tried using the new @slhck syntax :

    -vf "scale=if(gt(a\,1)\,650\,-2):if(gt(a\,1)\,-2\,650)"

    The result I got was :
