No, Diego's comment was wrong (as I pointed out in a reply). You can't expect that compress return codes are in the same range as AVERROR codes.
If they happen to be errno codes (which they aren't), you could do AVERROR(ret).
But in this case, you either would have to do a large overkill function trying to map compress return codes into corresponding AVERROR ones, or just have it return AVERROR_INVALIDDATA or AVERROR_UNKNOWN.
