  • Android FFMPEG slow

    22 juillet 2016, par Thommy

    I create a video with an overlay fading to merge this later with another video to get an overlayed video.
    Merging and co are working fine and fast, but creating the overlay-video with a fading picture is very slow (3 to 4 fps). Other operations like scaling run with 10 to 200 fps.
    Here is my ffmpeg command for creating the ovleray video.

    ../binary/ffmpeg -loop 1 -i ../overlay_0.png -t 21.534 -vf scale=1280:720,fade=in:st=21.034:d=0.05,fade=out:st=21.534:d=2.0 -pix_fmt rgba -vcodec png -threads 5 -preset ultrafast ../outfile.mp4

    Did I miss any commands to speed this up ?

  • How to download a 61th minute video for 5 seconds remotely ?

    18 octobre 2015, par user186259

    As you can quickly download video from a remote part of a large video file with ffmpeg ?

    ffmpeg -ss 01:00:00 -i http://example.com/videofile.flv -t 00:01:00 -vcodec copy -acodec copy file.flv

    Here I miss the first hour of video and download 61th minutes. It takes 20 minutes. Time of the operation = end of video and splitting it locally.

    How can I speed up the process ?

  • Ffmpeg only saves files but don't re transmit the stream in node

    3 juin 2018, par sonseiya

    am using ffmpeg to get a video stream, save a file and re send to another machine.

    Basicaly i am using the following command :

    ffmpeg -timeout 60 -i udp://192.168.0.12:3000 -c:v libx264 -c:a mp2 
    
-f tee -map 0:v -map 0:a 
    
"[onfail=ignore]6067_20180602_214828.ts|[f=mpegts]udp://192.168.0.12:4000"

    The file is being generating perfectly, my problem is that i am not getting the udp stream when i try to test it using vlc.

    Did i miss something ?

    I get the command from : https://ffmpeg.org/ffmpeg-formats.html#tee

    Regards
