File-format/codec combo for lossless encoding of grayscale

[TranzMatt]

I have some processed grayscale image/video data that I would like to stream off to one or more clients using lossless intra-frame-only compression.

1) Grab raw GRAY8 image/frame from memory pointer
2) Compress frame data using lossless compression
3) Put compressed frame data into media container
4) Stream (RTP) container pack to one or more clients.

A look at fourcc's site suggests either FFV1 or ZLIB could handle the codec part, but I'm not at all sure about the container/format. Can anyone help me with suggestions/guidance? Thanks.
