• AS3 AIR Detecting video play completion with FFMPEG

  21 août 2015, par AntBirch

  I’m using FFMPEG with AS3 as I need to be able to allow the use of multiple video formats. The problem I’m having is that whilst using FFMPEG the following netStatus will never get triggered - NetStream.Play.Stop

  I’ve tried adding onPlayStatus and onStatus to the client but it seems that FFMPEG doesn’t work with these either. The only way I currently have of knowing if the video is finished is by using "NetStream.Buffer.Empty" but this really isn’t practical and may cause issues in the long run.

  I previously had an issue with being unable to trace out the netStream duration with FFMPEG which resulted in the use of ProgressEvent. Is this function the way forward for my current issue ?

  Thanks in advance.

  EDIT 1 : It may be possible that because NetStream is a sealed class that I have to use an internal class to add the onPlayStatus function to it ? I’ve added netStream.client = new Client();

  EDIT 2 : Can’t seem to find a way to call onPlayStatus.

  EDIT 3 : Not sure if it’s worth noting but netStream.time never seems to match netStream.bufferlength when the video has finished.

  15 juin 2022, par parsa

  I've problem for the playing mp4 format videos on ios and sometimes it no have any problem and play correctly.

  Videos with mkv format stores In my server daily,

  And I copy the codecs to mp4 to can support video playing in ios with this command of ffmpeg :

  


  ffmpeg -i Axl_Rose.mkv -map 0 -c copy -c:a aac -movflags +faststart Axl_Rose.mp4


  


  Sometimes the output can not play in ios.
This is the ffprobe details of output file of top command which could not play on ios :

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

  19 avril 2021, par Engi Gang

  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 )

  


  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;
        }
        
    }
}
