  • How do I add a text for the 1st 30 seconds inside a filter_complex expression for each video part ?

    30 décembre 2022, par PirateApp

    I am generating a video grid using the following filter_complex command

    


    ffmpeg
     -i v_nimble_guardian.mkv -i macko_nimble_guardian.mkv -i ghost_nimble_guardian_1.mp4 -i nano_nimble_guardian.mkv
     -filter_complex "
         nullsrc=size=3840x2160 [base];
         [0:v] trim=start=39.117000,setpts=PTS-STARTPTS, scale=1920x1080 [upperleft];
         [1:v] trim=start=40.483000,setpts=PTS-STARTPTS, scale=1920x1080 [upperright];
         [2:v] trim=start=32.416471,setpts=PTS-STARTPTS, scale=1920x1080 [lowerleft];
         [3:v] trim=start=28.100000,setpts=PTS-STARTPTS, scale=1920x1080 [lowerright];
         [3:a] atrim=start=28.100000,asetpts=PTS-STARTPTS[outa];

         [tmp1][upperright] overlay=shortest=1:x=1920 [tmp2];
         [tmp2][lowerleft] overlay=shortest=1:y=1080 [tmp3];
         [tmp3][lowerright] overlay=shortest=1:x=1920:y=1080[v]
     "
     -map "[v]" -map "[outa]" -c:v libx264 -crf 17 -shortest -t 880 output4k.mkv


    


    How do I text to this video grid that will appear with a fade in at 10 seconds, stay for 30 seconds and then fade out ?

    


    enter image description here

    


    What I tried ?

    


    ffmpeg
     -i v.mkv -i macko_nimble_guardian.mkv -i ghost_nimble_guardian_subtle_arrow_1.mp4 -i nano_nimble_guardian.mkv
     -filter_complex "

         [tmp3][lowerright] overlay=shortest=1:x=960:y=540[v]
     "
     -map "[v]" -map "[outa]" -c:v libx264 -shortest -t '30' output2.mkv


    


    It gives me an error

  • FFMPEG stream to youtube crashing

    29 septembre 2022, par jakeb

    We have a script that runs FFMPEG and broadcasts a tab recording from puppeteer, it will run fine for a period of time, but if the chromium tab from puppeteer ends up doing certain things (playing a youtube video, for example) FFMPEG crashes. It doesn't matter if the video is 4k 60 FPS, or if it's a 480i video from 2009, the result seems to be the same.

    


    This is the FFMPEG command we're running :

    


    ffmpeg -loglevel info -i - -c:v libx264 -b:v 15000k -preset ultrafast -tune animation -force_key_frames "expr:gte(t,n_forced*2)" -sc_threshold 0 -c:a aac -minrate 15000k -s 1920x1080 -r 60 -vsync 1 -max_muxing_queue_size 1024 -max_interleave_delta 0 -f flv -flvflags no_duration_filesize "rtmps://a.rtmps.youtube.com/live2/*****"


    


    This is the output when it crashes :

  • I want to replace audio in a moflex file but ffmpeg says "Unable to find a suitable output format for 'CloudyWithAChanceOfMeatballs(3D).moflex'"

    26 septembre 2022, par Костянтин Мара

    What i do :

    


    ffmpeg -i CloudyWithAChanceOfMeatballs(3D)_400x240_1800kbps_23.976fps_2pass.moflex -i Cloudy.With.A.Chance.Of.Meatballs.2009.1080p.mp3 -c:v copy -c:a fastaudio -map 0:v:0 -map 1:a:0 -o CloudyWithAChanceOfMeatballs(3D).moflex


    


    and what i get :

    I'm not sure what could be the problem, before this i tried converting it to mp4 and then do something but because the video was in 3d, ffmpeg sort of shuffled those left and right frames into one, 2x long video. Help on this would also be welcome.
