  1. I want to use FFMPEG to merege multiple audios and one audio file that will contain all of them .

    Each audio file have some delay from the start - lets say that the first audio start 30 seconds after start ( the first 30 seconds will have white noise )

    And the second audio file will start 90 seconds after start.

    Each of the audio length is 35 seconds.

    How to do it ?

  3. the kind of the audio is simple wav files.
    i try to use this

    ffmpeg.exe -report - -i "Storage\\1.wav" -i "Storage\\2.wav" -i "Storage\\3.wav" -filter_complex "adelay=30000|30000" "adelay=91000|91000" "adelay=151000|151000" -c:v copy "Storage\\ALL.wav"

    but i get an error

    "count not write header form the output file - Error init out stream 0:8"

  4. For WAV files it's easy to get rid of the delay entirely using DelayCut.

    Or, can't you append the three audio files together to make a single file?

  6. Hello,

    I am using Mplayer command line tool to gather information from different files.
    When the parsed media contains a video stream, it is possible to specify the numbers of frames to read with the "-frames" option? It has to be at least 1 frame in order to get the applied aspect ratio; but when there is no video stream, like MPEG Elementary Stream, the only possible way I found to stop audio playback is to stop the process manually by pressing the 'q' key. How to stop audio playback after a specific time with MPlayer???
