• 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;
        }
        
    }
}


  


• Is there built in audio preprocessing within Android OS

  28 août 2022, par Larry lu

  I am running a dev team to build an Android application which the major feature is to record user voice and merge it into a long movie. It's a dub film application.

  


  One struggle thing to my dev team is whether the Android OS pre-process the recorded auido file. because we want the very original audio data from the built in Microphone.
If there is a built-in pre-processing inside of Android OS keep updating some data of the recorded aduio file, we want to know what is changed. We can't find any official post from Android speaking about it but would like to confirm from professional.

  


  Many thanks

  


• R create a video with imager and ffmpeg

  28 mars 2020, par Scrabyard

  I need to put 250 *.png-Files together in one video (mpeg). I installed ffmpeg and in my Enviroment-Variables (Windows 10) I added the path to the bin directory in Path-Variable.

  My *.png-files lay in folder "output" in directory of my R-file. I want ALL *.png-files in the movie.

  So I tried this R-Code, but it just won’t work, nothing happens when executing :

  library(imager)
  
  
  
  make.video(
  
    dname = "output",
  
    fname = "animation.mpeg",
  
    pattern = "%d.png",
  
    fps = 25,
  
    extra.args = "",
  
    verbose = FALSE
  
  )

  What is wrong with it, I used exactly the example from the official help...
