Support PCM_S16BE in WAVE

[Dennis]

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:

Out of curiosity: On which work-flow would this feature help?

I am closing this as a duplicate of ticket #1978.

[Dennis]

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.

[Carl Eugen Hoyos]

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?

[Dennis]

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?

[Dennis]

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.

You can test with the file attached to ticket #1978.

[Dennis]

Ah, thanks man.
...and you're right, it does not work.

The only program I could get to play the file was Winamp.

Thanks.

[Dennis]

Ticket 1978 say's this was fixed but I'm still unable to create a WAVE file with the original sample used in this ticket:

[Elon Musk]

You can not use pcm_dvd codec in wave format. What is not clear about such above message?

[Elon Musk]

You can not copy/mux incompatible codecs into another container.

[andrea]

Please add ffmpeg support to audio codec
pcm_s16be
into a MP4 container.
