  • Add black video to video with sound

    4 février 2017, par garrettlynch

    I’m trying to insert 13 seconds of black video at the start of a video that has sound using ffmpeg like so :

    ffmpeg -f lavfi -i "color=c=black:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
    "[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
    [blackstart] [1:v] concat=n=2:v=1:a=0[out]" \
    -map "[out]" -c:a copy output.mp4

    However the sound is not being maintained. What am I doing incorrectly ? -c:a copy does not seem to work should I be using a [1:a] somewhere ?

    garrett-retina:~ garrett-macbookretina$ ffmpeg -f lavfi -i "color=c=red:s=720x406:r=25:sar=1/1" -i input.mp4 -filter_complex \
    > "[0:v] trim=end=13,setpts=PTS-STARTPTS [blackstart]; \
    > [blackstart] [1:v] concat=n=2:v=1:a=0[out]" \
    >  -map "[out]" -c:a copy output.mp4

  • Using FFMPEG with Xvfb, Can't get a smooth video output

    13 juillet 2020, par Emax

    I'm trying to stream to twitch from a linux server, I've installed Xvfb and FFMPEG, the live starts fine, but I can't get a smooth video output.

    


    Setps :

    


    Xvfb :1 -screen 0 1920x1080x24 &amp;&#xA;export DISPLAY=:1&#xA;&#xA;&#xA;ffmpeg -probesize 60M -video_size "1920x1080" -framerate 60 -f x11grab -i :1.0 -f flv -ac 2 -crf 23 \&#xA;       -vcodec libx264 -g 120 -b:v 3000k -minrate 3000k -maxrate 3000k -pix_fmt yuv420p\&#xA;       -s "1920x1080" -preset veryfast -tune zerolatency -acodec libmp3lame -threads 4 -strict normal \&#xA;       -bufsize 12000k "rtmp://live-mil.twitch.tv/app/<key>"&#xA;</key>

    &#xA;

    I'm 100% sure that the app I'm trying to record output 60fps

    &#xA;

    Also the FFMPEG output is

    &#xA;

    I've also tryed to output the recording to an mp4 video file but I got the same result : a laggy video, It's like ffmpeg is recording the input at a lower framerate than 60, how can I fix this ?

  • Flutter streaming with FFmpeg_flutter_kit not reaching server

    22 juillet 2024, par Julio Cesar Reis

    I'm trying to stream my flutter screen to youtube using FFmpeg flutter kit. Everything seems fine but the output never reaches youtube server.

    &#xA;

      &#xA;
    1. log in using Yt flutter package.

      &#xA;

    2. &#xA;

    3. create a broadcast

      &#xA;

    4. &#xA;

    5. create the livestream and bind it to the broadcast

      &#xA;

    6. &#xA;

    7. get the ingestion address through LiveStreamItem.cdn.ingestionInfo.ingestionAddress

      &#xA;

    8. &#xA;

    9. stream the frames saved through FFmpeg :

      &#xA;

      final String rtmpUrl = "ls.cdn.ingestionInfo.ingestionAddress"

      &#xA;

      final String command = &#x27;-re -i $framePath -c:v libx264 -f flv $rtmpUrl&#x27;;

      &#xA;

      await FFmpegKit.execute(command);

      &#xA;

    10. &#xA;

    &#xA;

    But at the end I get errors like SESSION_NOT_FOUND, or the stream never reaches the server which keeps my broadcast as ready and not active so I can't go live.

    &#xA;

    I've tried using the ingestionAddress plus the streamName separated by a slash, I've tried the direct stream using rtmp ://x.rtmp.youtube.com/live2/MY_API_KEY but none of that worked.

    &#xA;
