  • How to lower the volume in a specific time interval with ffmpeg.exe [on hold]

    1 December 2013, by user1604523

    I am trying to lower the volume in a specific time interval with ffmpeg.exe . Let's say I have a 5 minutes long video and I want to lower the volume between 00:01:30 and 00:02:00. I read that we can use different parameters at the same time but I couldn't figure it out.

    Any help would be greatly appreciated.

  • How to minimize the delay in a live streaming with ffmpeg

    9 July 2013, by Pasquale C.

    i have a problem.
    I would to do a live streaming with ffmpeg from my webcam.

    1. I launch the ffserver and it works.

    2. From another terminal I launch ffmpeg to stream with this command
      and it works:

      sudo ffmpeg -re -f video4linux2 -i /dev/video0 -fflags nobuffer -an http://localhost:8090/feed1.ffm

    3. In my configuration file I have this stream:

      <stream>
      
Feed feed1.ffm
      
Format webm
      
 NoAudio
      
 VideoCodec libvpx
      
 VideoSize 720x576
      
 VideoFrameRate 25
      
 # Video settings
      
    VideoCodec libvpx
      
    VideoSize 720x576           # Video resolution
      
    VideoFrameRate 25           # Video FPS
      
    AVOptionVideo flags +global_header  # Parameters passed to encoder 
      
                                    # (same as ffmpeg command-line parameters)
      
    AVOptionVideo cpu-used 0
      
    AVOptionVideo qmin 10
      
    AVOptionVideo qmax 42
      
    #AVOptionVideo quality good
      
    PreRoll 5
      
     StartSendOnKey
      
    VideoBitRate 400            # Video bitrate
      
 </stream>

    4. I launch the stream with

      ffplay http://192.168.1.2:8090/test.webm
      It works but I have a delay of 4 seconds and I would to minimize this delay because is essential for my application.
      Thanks
