Dead Ends

Common approaches that don't work:

  1. Manually compress images in the subscriber callback 80% fail

    Bypasses image_transport entirely; loses bandwidth-efficient transport and standard interface

  2. Use raw transport and accept the bandwidth cost 70% fail

    Raw HD images over WiFi or limited bandwidth saturate the link; drops frames
