  • ffplay is not getting compiled on Amazon EC2

    12 septembre 2017, par Durgesh

    Asking this question as similar questions of stackoverflow didn’t help me.

    I wanted to install ffplay tool on my Amazon EC2 (Linux) instance. I have cloned the code from FFmpeg’s official git repository.

    executed ./configure and make. After these commands, there was no ffplay binary created. Only ffmpeg, ffprobe and ffserver binaries were generated.

    Later tried with executing ’./configure —enable-ffplay’ as suggested in few posts of web. Even this didn’t work. Also i did not found any static binaries of ffplay which i could use for my testing

    Can anyone suggest what was wrong with my build procedure ?

  • NVIDIA accelerated ffmpeg (nvenc_h264 ) is dead slow on Amazon G2 instance

    16 novembre 2015, par Abhijit Pathak

    FFMPEG when compiled with following options give abysmal performance on Amazon G2 instance( g2.2xlarge, GRID K520) when compared with standalone Dell-Precision-T1700 (Quadro-k620)

    "--enable-nonfree --enable-gpl --enable-version3 --enable-shared --enable pthreads [b]--enable-nvenc[/b] --enable-runtime-cpudetect --disable-doc --enable-libmp3lame"

    Above ffmpeg binary took 66 seconds to transcode 5.22 mins BVE_Localize.mp4 file with following command.

    time ffmpeg -y -i BVE_Localize.mp4 -strict -2 -vcodec nvenc_h264 -b 5000k -acodec aac -ab 256k -f mpegts BVELocalize.ts ( took 1m6.990s on G2)

    When same ffmpeg command is executed on Dell-Precision-T1700 (Xeon Dual core, Quadro K620) based workstation takes 0m41.572s.

    I would like ffmpeg to perform better on Amazon G2 instance. What do you think I might be missing ? My Amazon G2 instance configuration is Ubuntu 14.04 64 bit, Cuda 7.0 , 352.55 drivers, MSI disabled,NVIDIA SDK 5.0.1

  • How can I read System.Drawing.Bitmaps from a video file using FFMpegCore ?

    18 avril 2021, par David Sackstein

    I am using https://github.com/rosenbjerg/FFMpegCore to write System.Drawing.Bitmaps to a video file and to read them back as bitmaps.

    


    Based on the examples I was able to implement the first step as so :

    


    public static void WriteToH264(System.Drawing.Bitmap[] bitmaps, string fileName)&#xA;{&#xA;    Directory.CreateDirectory(Path.GetDirectoryName(fileName)!);&#xA;&#xA;    WriteToH264(&#xA;        bitmaps.Select(bitmap => new BitmapVideoFrameWrapper(bitmap)),  &#xA;        4,            &#xA;        fileName);&#xA;}&#xA;&#xA;private static void WriteToH264(IEnumerable<ivideoframe> bitmaps, int frameRate, string fileName)&#xA;{&#xA;    var videoFramesSource = new RawVideoPipeSource(bitmaps)&#xA;    {&#xA;        FrameRate = frameRate&#xA;    };&#xA;  &#xA;    FFMpegArguments&#xA;        .FromPipeInput(videoFramesSource)&#xA;        .OutputToFile(fileName, true, options => options&#xA;            .WithVideoCodec(VideoCodec.LibX264))&#xA;        .ProcessSynchronously();&#xA;}&#xA;</ivideoframe>

    &#xA;

    For the second part I need to implement the following function using the same library :

    &#xA;

    public static System.Drawing.Bitmap[] ReadFromH264(string fileName)&#xA;

    &#xA;

    But I have not find an samples of how to do this.

    &#xA;

    How should I implement this function ?
