  • General ffmpeg command for encoding all formats to FLV [migrated]

    12 septembre 2011, par Adam

    I am creating a video sharing/tube site and I'm in need of a single good general purpose ffmpeg command to use to transcode any video that's uploaded by my users.

    I'm surprised more people haven't published good examples of a good general ffmpeg command for converting to flv format. By general, I mean being able to specify an input file in any format (wmv, avi, webm, etc.) and produce an FLV file that has great quality.

    I am looking for a single ffmpeg command that can :

    • Produce great looking video for the web (no artifacts, maintain original quality etc.)
    • But also reduce file size to make it web friendly

    I realize these are competing requirements and I would consider video quality to be the priority when it comes to a tradeoff but at the same time, I know you can have great quality and still reduce the file size of the original file dramatically.

    I would have used MP4 with H264 but the patent stuff scares me and I don't want to pay for that so I'm stuck with FLV.

  • Using the C# Lambda Operator

    16 février 2018, par SvenskaKocken

    I am trying to understand how the lambda operator in C# is used when the given parameters are formatted in ( ), like so :

    _backgroundVideoWorker.DoWork += (s, e) => 
    
       { 
    
           outputFile = _videoEditor.JoinVideo(selectedConfiguration, videoFiles); 
    
       };

    My main goal from asking this question is to understand how the different operators are being used with the lambda, += (s, e) =>.

    For reference, this code excerpt is taken from an application that is joining two video files together by using the FFMPEG utility.
