[Libav-user] Encoding and Decoding Single Frames with libAV

[James Board]

Is there a way to use libav to encode and decode a single frame of
image data with a lossless codec such as ffvhuff?  I know this can
be done with video.  But if I have a single frame of image data stored
in a ppm or pnm file, can I read it into my libAV program, compress with
the ffvhuff codec, and then write the compressed output to a file?  And
later, do the reverse?
