Adding any on the fly compression is going to inherently add some latency
(maybe a lot depending on the level of compression). Is this acceptable for
your application? But yeah, an encoder chip sounds good. If not, you might
need an FPGA or second PIC32 dedicated to the encoding. Select lowest level
of compression for the least demand placed on the PIC32's resources.
