[Live-devel] Live555 with ffmpeg's MJPEG codec

Ok I am setting it properly now, using gettimeofday(), however why is it 
needed in the case of a jpeg frame? Also, since my code runs on a 
windows platform, I had to download a custom implementation of this 
function.

If I don't use live555 it works just fine: i.e. encode to a memory 
block, decode from a memory block.  I tried comparing the original jpeg 
compressed data with the received data and it seems that the jpeg header 
is broken. Could it be that JPEGVideoRTPSink fails to reconstruct the 
original JPEG header for some reason? I'll try running openRTSP now.
