• ffmpeg closes with operation not permitted in android

  27 avril 2022, par DevSharma

  I am running FFmpeg in my app and specifically in "Android 11" I am getting this error from several users

  


  I have researched a lot but no solution found.

  


  I thought there is something wrong with the codec parameter that is being passed since it is saying "incorrect codec parameters" but most of the parameters looks good.

  


  also verified if all the required file permission are granted and those are good too

  


  now I m unable to find the problem,

  


  please help, thanks

• How to allow other site via nginx to use my content ?

  3 septembre 2020, par GG GG

  i use nginx - rtmp technique to restream the m3u8 stream via ffmpeg and then play it on the website. I have following restream m3u8 from my server, which is playable perfetly in vlc player https://hls.tvoti.com/rtl2/playlist.m3u8
But i can not play it on the website see demo. I use following code to allow website use the stream, and is it not correct ? :

  


  server {
    listen   80; 

    #root /var/www/html/; 
    #index index.php index.html index.htm;

    server_name tvoti.com;

            set $cors_origin "$http_origin";
        }

    add_header "X-Dbg" "$cors_origin" always;

            add_header "Access-Control-Allow-Origin"  "$cors_origin";
        }

• ffmpeg join filter ignores audio of one input

  18 mai 2021, par regstuff

  I'm taking an audio input from a pulseaudio virtual source and trying to combine that with the audio & video of an rtmp input, and the final output goes to another rtmp.

  


  When I try ajoin, as below, I get a message : [Parsed_join_0 @ 0x2cc9100] No channels are used from input stream 1.
The output has audio only from the first source.

  


  PULSE_SOURCE=vmic ffmpeg -f alsa -i pulse -i rtmp://127.0.0.1/server/stream1 -filter_complex "[0:a][1:a]join=inputs=2:channel_layout=stereo[a]" -map "[a]" -map 1:v -vcodec copy -f flv rtmp://127.0.0.1/server/stream2  


  


  Using amerge, as below, however works, though it throws the message : [Parsed_amerge_0 @ 0x38b70c0] No channel layout for input 1
Output has the merged audio.

  


  PULSE_SOURCE=vmic ffmpeg -f alsa -i pulse -i rtmp://127.0.0.1/server/stream1 -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map "[a]" -acodec aac -ac 2 -b:a 128k -map 1:v -vcodec copy -f flv rtmp://127.0.0.1/server/stream2


  


  FFMPEG documentation however says ajoin should work. Found this SO comment that says ajoin can't do this however.

  


  Any pointers ?
