  I'm trying to make a video with a picture and 7 hours of wav,There is always a few seconds less audio at the beginning of the video, and the sound becomes smaller.

  One more thing..As of now I am trying to cross-compile ffmpeg on ubuntu,But If I just compile it for linux..The same command doesnt gives any error and executes smoothly and then I am able to get ffmpeg with aacplus support for my linux machine, But why the problem is coming when I am cross compiling it.

  Another thing as aacplus is not on by default, If in configuration I dont put any (off by default) library support like if I remove aacplus from it, Then also it goes smoothly.

  Help please ASAP
