    Default Help with FFMPEG!!!

    Hi All

    I am new to FFMPEG , i am working on to convert multiple input audio streams to a single audio stream by using the following command

    ffmpeg -i tea_break.wav -i beer.wav -map 0:0 -map 1:0 -acodec wmav1 -ar 44100 -ab 384k -y sample.wav -acodec wmav1 -ar 44100 -ab 384k -newaudio

    And it works fine it genearats the sample.wav and when i play it , it plays both the input streams seperately without any sound synchronization issue except it plays beer.wav first instead of tea_break.wav.

    Another issue is that when i input more than two files like

    ffmpeg -i tea_break.wav -i beer.wav -i morse.wav -map 0:0 -map 1:0 -map 2:0 -acodec wmav1 -ar 44100 -ab 384k -y sample.wav -acodec wmav1 -ar 44100 -ab 384k -newaudio -acodec wmav1 -ac 44100 -ab 384k -newaudio

    this command generates the sample.wav successfully but not with proper data , this sample.wav plays the morse.wav in all audio means it overlaps over tea_break.wav and beer.wav and plays . But it should play first tea_break.wav then beer.wav then morse.wav seperately.

    Please help me out on this , i am really banging my head from last two days

    Thanks
