  • suitable video encoding for browsers

    26 juin 2022, par seriously

    I was researching how illegal movie streaming services handle all the traffic they get and to understand that I had to follow the steps they perform to get the video data to the users. I got to the stage of video transmission and noticed something that boggled me. Most of the illegal movie streaming sites get their movies/tv-shows through piracy/torrents and even most of the streamers are sister companies of the piracy websites. Now when I took a look at the video encodings of the torrent movies and shows they are h.265 but h.265 is not supported by popular browsers like chrome, firefox edge... Does this mean they (the streamers) have to re-encode every h.265 videos to avc/h.264 before they stream it ? If that's the case, that takes them a huge amount of time to convert their whole movie catalog to h.264 not to mention the space they require to save them. Am I taking a look at this the right way ? Do they really convert and store 2, 3 ... differently encoded video files and stream the suitable one ? Or can they somehow convert the chunks of data they are streaming to h.264 live simultaneously without having to store the h.264 formats hence saving conversion time and space ?

    


  • How to combine three ffmpeg commands into one ?

    26 juillet 2018, par Nane

    I am pretty confused that how to combine three ffmpeg commnads into one which also consists of two inputs.

    // rescale with certain dimension 
    
ffmpeg -i front.mp4 -filter_complex scale=600:400 rescale.mp4
    

    
//Attach to image
    
ffmpeg -i 600800.jpg  -i rescale.mp4 -filter_complex "overlay=(W-w)/2:(H-h)/2" final.mp4
    

    
// After Changed to specific even size Burn Subtitles with Draw Text
    
ffmpeg -i final.mp4 -filter_complex "drawtext=fontfile=Lucida Grande.ttf:text='I am TEXT':fontsize=72:fontcolor=white:x=50:y=100,subtitles=sample.srt:force_style='Fontsize=22,OutlineColour=&H55000000,BorderStyle=3'" CheckMe.mp4

  • can we use -vf and -filter:a with -filter_complex

    15 avril 2021, par Eswar T

    I want to combine some videos with some specific features like(video Speed, volume increase, resolution, rotation, framerate) of the final output of the video
We can do this process in 2 steps like

    


    Combine video

    


    ffmpeg -i test1.mp4 -i test2.mp4 -filter_complex [0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[outv][outa] -map [outv] -map [outa] output.mp4


    


    Then apply filters

    


    ffmpeg -i output.mp4 -filter:a volume=1.0,atempo=1.0 -vf transpose=2,setpts=1/1.0*PTS,scale=3840X2160,fps=30 final.mp4


    


    I can do it this way but is there any way to do it in 1 step

    


    thank you
