 Replying to [comment:2 halaei]:
 > Please run the command using 2 versions of ffmpeg. The input data is the
 same but output changes.

 Why is this an issue?

 > Was this due to a bugfix or is it a new bug?

 Please run `git bisect` and tell us!

 > I don't know what is vague here!

 Mostly that you didn't tell us what you don't like about the current
 output.

 > The command just prints samples as 16bit signed integers in binary
 little endian format.
 > Same input should give same output.

 This is not true in every case (think of multi-threaded encoding), and
 certainly not across different versions.
