Using -pix_fmt gray16 creates incorrect AVI

Description

I create AVI with the following command.

ffmpeg -i "input.avi" -pix_fmt gray16 -c:v rawvideo output.avi

I get a warning:

[avi @ 0000000002bef880] gray16le rawvideo cannot be written to avi, output file will be unreadable

The file has fourcc 0x00000000 and is recognized by video players as RGB555.

I think it is more correct to record fourcc 'Y16 ' (0x20363159).

  • Keywords avi added

Please provide a file containing gray16 that plays with Windows Media Player - the relevant application for avi. We prefer not to invent new mappings for avi, use nut instead.

Or ask Thermoteknix for a sample.
