Description
Summary of the bug:
It appears FFmpeg does not support PCM signed 16-bit big endian in WAVE. I believe this should be supported by the RIFX file format.
How to reproduce:

Okay, thanks.
These are Michael Jackson music videos that came on a bonus disc.
As a work around I just convert the audio to little endian.

Replying to DJX:

What I meant is: If above command line (with -acodec copy or -acodec pcm_s16be) would work, what would you do with the resulting rifx/wavx file?

I was just going to play with them, nothing important.
First thing that comes to mind is: I was going to put them in a DAW and analyze to check if the audio truly is uncompressed as is (or if it was compressed before being sampled into its current format).
...prob nothing I couldn't do by converting it to little endian but I wanted to keep the audio stream untouched.

(Disclaimer: I don't know what a DAW is.)
I wanted to know why (or if) you expect that the software (or hardware) you want to use with the rifx wave files would be able to read such a very unusual format?

Oh, no problem.
I was going to mess with it in a digital audio workstation (DAW)/editor.
Hmm, guess I didn't think it was that unusual.
...now you got me wondering if, indeed, it would have worked...who knows.



Out of curiosity: On which work-flow would this feature help?
I am closing this as a duplicate of ticket #1978.
