  • Video cutting with ffmpeg with standard i/o

    15 octobre 2023, par Крошка Сын

    I'm struggling with the problem of cropping moments and applying the "blur" effect in ffmpeg from under c#. Here is my process startup code :

    


    _ffmpegProc = new Process
    {
        StartInfo = new ProcessStartInfo
        {
            RedirectStandardInput = true,
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            UseShellExecute = false,
            CreateNoWindow = true,
            FileName = "/usr/bin/ffmpeg"
        },
        EnableRaisingEvents = true
    };


    


    Here is the I/O code via streams :

    


    using (Stream inpt = new MemoryStream(input))&#xA;    {&#xA;        inpt.CopyTo(_ffmpegProc.StandardInput.BaseStream);&#xA;        _ffmpegProc.StandardInput.Close();&#xA;    }&#xA;&#xA;    var response = Array.Empty<byte>();&#xA;    using (var output = new MemoryStream())&#xA;    {&#xA;        _ffmpegProc.StandardOutput.BaseStream.CopyTo(output);&#xA;        response = output.ToArray();&#xA;    }&#xA;</byte>

    &#xA;

    The problem occurs when I want to crop the video, namely, as soon as I add the -ss hh:mm:ss flag -to hh:mm:ss, an error immediately pops up :

    &#xA;

    &#xA;

    System.IO.IOException : Connection timed out ---> System.Net.Sockets.SocketException (110) : Connection timed out

    &#xA;

    &#xA;

    Here is the argument I use to crop video fragments :

    &#xA;

    var arg =&#xA;        $"-i - -ss 00:01:05 -to 00:03:10 -c copy -f matroska -";&#xA;return StartFfmpeg(arg, input);&#xA;

    &#xA;

    Moreover, if I remove the -to hh:mm:ss flag, then everything will be fine.&#xA;If you look at the ffmpeg log, then everything works fine there&#xA;As far as I understood, the error happens exactly when transferring already from ffmepg

    &#xA;

    I've tried a bunch of different libraries, but they don't fit because of weak stream support

    &#xA;

    Audio extraction, video creation from pictures, transcoding everything works, but for some reason with video cropping I can't even figure out where to look to find an error

  • How to set profile compatibility and level indication of an fMP4 using ffmpeg ?

    27 novembre 2014, par Pablo Montilla

    I’m using ffmpeg to generate a fragmented mp4 stream that will be consumed by an HTML5 player using MSE. I think I have a correctly formatted mp4 stream of data with an empty moov at the start and a series of moof+mdat for the video fragments. What I’m stuck is with the codec that’s being received by Chrome.

    chrome ://media-internals has this to say :

    00:00:00 00 pipeline_state  kCreated
    
00:00:00 00 EVENT           PIPELINE_CREATED
    
00:00:00 00 EVENT           WEBMEDIAPLAYER_CREATED
    
00:00:00 00 url             blob:http%3A//localhost/3388b7f1-5567-4d76-a585-0b247affd16a
    
00:00:00 00 pipeline_state  kInitDemuxer
    
00:00:07 68 error           Video codec: avc1.4d401e

    From which I gather the problem is with the encoded data, which should be in avc1.4d0020 as its specified in the javascript.

    I’ve seen the answer to html5 video tag codecs attribute, which tells me I need to reset profile_compatibility and AVCLevelIndication, but I couldn’t find an option to do that.

    Here’s the command line I’m using (the pipe is read and sent to the web page using web sockets) :

    ffmpeg -re -i Input.mp4 -map 0:0 -y -c:v libx264 -preset veryslow -x264opts intra-refresh=1 -tune psnr -refs 1 -b:v 1500k -bf 0 -g 8 -b-pyramid none -f mp4 -movflags empty_moov+omit_tfhd_offset+frag_keyframe -frag_duration 1000000 -profile:v main -iods_video_profile 0 -flags +loop \\.\pipe\FeedPipe

    So the question is, can I set the profile_compatiblity and AVCLevelIndictation in the ffmpeg command line ?

  • configure : Separate commonalities in msvc and icl flags

    30 mai 2013, par Alex Smith
    configure : Separate commonalities in msvc and icl flags

    Allows for easier handling of flags that may be specific to icl or msvc.
    
Furthermore, simplify the handling of warnings and remarks thanks to
    
icl’s support of -Wall on Windows.
