[FFmpeg-user] RGB uncompressed: Which format to use?

[Peter B.]

Hello,

I'm trying to convert the SGI image sequences from SVT (from VQEG's FTP
[1]) to video files and convert them to different bits-per-pixel RGB
pix_fmts (Source is rgb48be).

Is there any uncompressed codec and container capable of containing the
following pix_fmts?
PIX_FMTS_RGB8="rgb0 rgb24 bgr0 bgr24"
PIX_FMTS_RGB16="bgr48le bgr48be rgb48le rgb48be"

I've tried using vcodec=rawvideo and AVI as container (*), but with
rgb48be trying to ffplay the resulting file displays the following error
message:
