Someday we will support RTP header extensions (though not necessarily

More generally, though, I'm curious about why people are still
interested in JPEG-over-RTP, especially with very large JPEG images.
JPEG is a *terrible* codec to use for video; it doesn't have any of
the inter-frame prediction/compression features that real video codecs
have.
I know your opinion on this topic.
The reason why people is still interested in JPEG streaming is that
hardware MPEG4 and H264 encoders often simply don't support higher
resolutions (for example, MPEG4 on TI DaVinci platforms is limited to
1280x960, and H264 has a resolution limit that's only a tad higher),
while JPEG encoder often support resolutions of up to 10K x 10K pixel.
So often, especially when you have to stream big frames, MJPEG is all
you have, and you got to live with it. That's why people still are still
interested in it (for sake of completeness there's another - secondary -
reason, i.e. retrocompatibility with older software).
