Patch attached that imo makes using z16 a little easier,
will push if there are no objections.

Re: [FFmpeg-devel] Add 16-bit Depth pixel format

2018-11-28 Thread Pablo Rubio Fernández 
Yes, it is like gray16. But gray16le is already in use to Y16 pixel format.
For this reason, I think that best way to add Z16 pixel format is creating it.
I'm not an expert, any help will be appreciated.

[FFmpeg-devel] Add 16-bit Depth pixel format

2018-11-19 Thread Pablo Rubio Fernández 
Hi all!
It's my first time here. I want to create a patch to add Z16 pixel format.
I have did some changes, and I want to know if I'll need change any other
file.
I attach my current patch.
Thanks in advance.
