  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Stream to Azure Media Service from ffmpeg, stream can not be played

    24 juillet 2015, par Simon

    i try to send a stream from my RaspberryPI with debian wheezy to the AzureMediaService.
    I followed the instructions of this nice post.
    http://gtrifonov.com/2015/07/02/streaming-live-video-from-raspberrypi-to-azure-media-services/

    After a lot of trouble with the ffmpeg and libx264 builds i think i have it working now, to stream to the rtmp urls.

    INGESTURI="rtmp://office-klokklokmediastream.channel.mediaservices.windows.net:1935/live/3e541bc149754ebd975b95ec3583c949/mystream1"
    
ffmpeg -framerate 30 -r 30 -s 640x480 -i /dev/video0 -vcodec libx264 -preset ultrafast -acodec libfaac -ab 48k -b:v 500k -maxrate 500k -bufsize 500k -r 30 -g 60 -keyint_min 60 -sc_threshold 0 -f flv $INGESTURI

    But when i try to watch the link in azure portal publish link or with the azure amsmediaplayer it tells me (i have reseted the channel already) :

    "The video could not be loaded, either because the server or network failed or because the format is not supported."

    The public stream url is :

    http://klokklokmediastream.streaming.mediaservices.windows.net/30c3920e-420a-4d33-8938-e79d0db240ff/c9fd3479-0d4b-4643-a3f9-5fd5831985d0.ism/Manifest

    In the linux shell i see the following output while streaming, looks for me as send stream is working :

  • orangepi zero 2w, ubuntu, using a usb webcam ffmpeg to record videos, low FPS [closed]

    28 janvier, par Qingfu Shi

    I use a OrpangePi zero 2w, USB HIK 2K Cam, to record videos.
Ubuntu, ffmpeg installed,
the cmd

    


    ffmpeg -f v4l2 -video_size 1920x1080 -r 25 -input_format mjpeg -i /dev/video1 -vf "transpose=1" -c:v libx264 -preset fast -crf 23 output.mp4


    


    I want the fps to be at least 25, so it looks smooth, but I only got about 4.7 fps.

    but I want the video at least 1080p@30fps. What's the bottleneck ? is it possible to modify the cmd to achieve this ?
OrangePi zero 2w, use an AllWinner H618 cpu, with 1G RAM, 64G v10 sd-card.

    


  • Generating video from images and audio by FFmpeg

    24 mars 2020, par Cody

    I am new to FFmpeg and video/audio encoding. I try to use Fluent ffmpeg to generate a MP4 video from images and audio.

    There are 2 inputs only :

    If the audio duration is longer video length, just discard the excessive part of audio at the end.
    And all the images have to be shown in same duration.(i.e. The video should be in n/d FPS for n images and video with d second)

    Since the image input are not in number sequence, I use concat demuxer as input :

            let VIDEO_DURATION = 8;
    
        let ffmpeg = await FfmpegUtil.createCommand();
    
        let imageFiles: string[] = ["foo.jpg", "bar.jpg", ...]; //assume there are 67 image files
    
        let demuxerFile = await FfmpegUtil.createConcatDemuxerFile(imageFiles);
    
        let audioFile: string = "path/to/audio.wav";
    

    
        ffmpeg.input(demuxerFile)
    
            .inputOption(
    
                "-f", "concat",
    
                "-safe", "0",
    
            )
    
            .input(audioFile)
    
            .outputOption(
    
                "-r", `${imageFiles.length}/${VIDEO_DURATION}`,
    
            )
    
            .duration(VIDEO_DURATION)
    
            .save("path/to/output.mp4")
    
        ;

    it will spawn a ffmpeg command :

    ffmpeg 
    
    -f concat 
    
    -safe 0 
    
    -i path/to/demuxerFile.txt 
    
    -i path/to/audio.wav 
    
    -y 
    
    -r 67/8
    
    -t 8 
    
    path/to/output.mp4

    However the output file cannot be played.

    I also tried "-framerate", ${imageFiles.length}/${VIDEO_DURATION} in .outputOption(), it still output a file cannot be played and I found the frame rate always be 25 in its file property.

    Update 1 (added spawned command & ffmpeg console log) :

    spawned ffmpeg command & console log ("-r", `${imageFiles.length}/${VIDEO_DURATION}` as outputOption) :

    ffmpeg -f concat -safe 0 -i path/to/demuxerFile.txt -i path/to/audio.wav -y -r 67/8 -t 8 path/to/output_r.mp4
