• My (FFMPEG issue ) RTMP server(freebsd) wont let me hear video when I play a huge file over the server itself :/

  19 avril 2021, par Engi Gang

  Hey my name is Alisha from Norway im trying to get my RTMP server working the thing is that it works just fine but I just cant stream over it with ffmpeg I can stream to it on OBS and it works fine, but I am trying to a website where people could watch old public domain movies from the 1950 some of the films are actually pretty big lol.... anyways I detailed bellow more

  


  rm -rf /mnt/hls/loool && ffmpeg -re -i "$file" -c:v libx264 -c:a aac -b:v 300k -b:a 95k -f flv -flvflags no_duration_filesize rtmp ://lambright.xyz:1935/live/loool

  


  any work around I literally cant play the audio :( I can only hear (my source file is an MKV and 3gb )

  


  Note I had a smaller mp4 file and it did played the audio, the video isnt even playable in chrome but on VLC it is, but only a small file worked fine... its fine when I stream from my pc, but whats the point I am trying to set up my vintage 1950 serverbox :') trying to build a nice website where users could watch neat and decent old movies that are public domain if you wonder :/

  


  Another note when I am trying to play it on my iphone safari browser it does actually play parts but audio is super corrupted like you hear the audio sometimes :((

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application live {
            allow play all;
            live on;
            record off;
            hls on;
            hls_nested on;
            hls_path /mnt/hls/;
            hls_fragment 2s;
        }
        
    }
}


  


• Overlay timelapse video on solid background colour using ffmpeg

  13 septembre 2020, par hamchapman

  I've got a load of screenshots of a homepage that are named homescreen000001.png, homescreen000002.png, etc and I'm trying to create a time-lapse video of these images using ffmpeg.

  



  I've got it working in general when I run the following :

  



  ffmpeg -f image2 \
       -i ~/Desktop/homescreen%06d.png \
       -r 0.5 \
       -s 1440x900 \ 
       -b:v 1M \
       -vcodec libx264 \ 
       -pix_fmt yuv420p \
       ~/Desktop/timelapse.mp4


  



  However, it turns out that some of the images have transparent backgrounds so the background is showing up as black on those images.

  



  I'd like a white background so I've been trying to set that up using ffmpeg as follows :

  



  ffmpeg -f image2 \
       -loop 1 \
       -i ~/Desktop/whitebg.png \
       -i ~/Desktop/homescreen%06d.png \
       -filter_complex overlay \ 
       -r 0.5 \
       -s 1440x900 \ 
       -b:v 1M \
       -vcodec libx264 \ 
       -pix_fmt yuv420p \
       ~/Desktop/timelapse.mp4


  



  Here whitebg.png is 2px x 2px png with a white background, and that's it.

  



  This ffmpeg command produces a really tiny (in file size) video that's just a white background.

  



  Can anyone explain how I can overlay the images as a time-lapse video over a white background using ffmpeg ?
