gray16 pixel format

[Michael Koch]

When the available pixel formats are listed with
ffmpeg -pix_fmts
then "gray16" is not found in the list (however "gray16le" and "gray16be" are listed).

On the other hand, if I use "format=gray16" in the filter chain or "-pixel_format gray16" as a command line option, then I get no error message and no warning.

That doesn't seem to be right. If "gray16" is an alias for either "gray16le" or "gray16be", then it should also be listed with ffmpeg -pix_fmts

P.S. And it would be helpful to see for which pixel format the alias is, "le" or "be".

Well, the same as with
IO... p010le 3 15 10-10-10
IO... p010be 3 15 10-10-10

Or
IO... yuva420p9be 4 22 9-9-9-9
IO... yuva420p9le 4 22 9-9-9-9
IO... yuva422p9be 4 27 9-9-9-9
IO... yuva422p9le 4 27 9-9-9-9
IO... yuva444p9be 4 36 9-9-9-9
IO... yuva444p9le 4 36 9-9-9-9

Lacking common sense in this report. This is endian thing, no time to teach common knowledge on tracker. Do research on concepts if so much involved in reporting (invalid) bugs.

Any pixel format > 8bit have alias, on LE system it is le variant on BE system it is be variant of pixel, in other words native to system endianess.

[Balling]

No, this is cosmetic issue that the default is not clarified. Or disallow gray16.

Replying to Elon Musk:

Any pixel format > 8bit have alias, on LE system it is le variant on BE system it is be variant of pixel, in other words native to system endianess.

This is an important information and missing in the official documentation. Those alias are not listed with the command "ffmpeg -pix_fmts".

It is redundant and self explanatory.
