Ross already posted this link recently:

…and now you’re asking how you can make the packets even bigger?
If inter-frame compression is the problem, then how about I-frame-only H.264,
which will let you break each picture up into slices so the whole picture isn’t
lost if one packet is lost, and no subsequent pictures will fail to decode due
to not having any dependence on prior pictures?
The overall bit rate should be about half that of comparable quality MJPEG due
to superior still picture coding techniques incorporated during the ~10 years
between the standardization of these two codecs.
If it absolutely *has* to be MJPEG, then you could pull off the same slicing
technique yourself, with custom reassembly on the other side. A 4k image can
be seen as four 2k images, for example.
