  • Can't figure out how to get ffmpeg to save to an odd file extension

    30 septembre 2015, par dinki

    I’m working on a network encoder for SageTV. I get request from the SageTV with certain filenames. I’m trying to capture video from my capture card and write out to a file called

    ’D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-
    0.mpgbuf’

    Here’s the command I’m using :

    C :\Users\User>C :/Users/User/Desktop/ffmpeg-20150928-git-235381e-win64-static/bin/ffmpeg.exe
    -f dshow -crossbar_video_input_pin_number 2 -i video="ATI AVStream Analog Capture"
    D :\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf

    When I run that command, I get this error :

    [NULL @ 00000000087f9160] Unable to find a suitable output format for 'D:\Media\
    
tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf'
    
D:\Media\tvrecordings\RokuNetworkEncoderonlocalhost4510TVTuner-0.mpgbuf: Invalid
    
 argument

    But if I change .mpgbuf to .mpg it works fine . I am forced to use that filename though. Is there an easy way to do this ?

  • How to save frames to the video using their timestamps (variable frame rate, vfr, PyAV)

    9 juillet 2019, par Vladyslav Moisieienkov

    Shorty, I would like to write frames to the video according to their timestamps. FFmpeg example could be found here - How do I render a video from a list of time-stamped images ? , and I need something like that in Python. Probably PyAV library should be used as it provides bindings for FFmpeg. Maybe, it also possible by using OpenCV.

  • How to save file to s3 after processing by ffmpeg using carrierwave

    25 septembre 2013, par loganathan

    I am trying to convert the bit rate of the Mp3 file before uploading to S3, I can able to create version for the mp3 file but the version is not saving in s3 instead original file is uploading to s3.

      version :bitrate_96k do
    
    process :resample => "96"
    
  end
    

    
def resample(bitrate)
    
    tmp_path   = File.join( File.basename(current_path), "tmpfile" )
    
    File.rename current_path, tmp_path
    
    audio_details  = `ffmpeg -i '#{tmp_path}' 2>&1`.split(",").split("\n").flatten
    
    file_bitrate =  audio_details.grep(/bitrate/).grep(/bitrate/).join.split("bitrate: ").last.split("\s").first
    
    unless file_bitrate == bitrate
    
      `ffmpeg -i #{tmp_path.shellescape}  -acodec libmp3lame -y -ab 96k #{current_path.path}`
    
      File.unlink(current_path)
    
     FileUtils.mv(temp_path, current_path)
    
    end
    
  end
