i´am using the live555 for jpeg streaming and it´s great.Thanks at all.
my question is about the maximun jpeg size i can
stream if i´don´t compress the file ?
i´m trying with the 227kb jpeg and the
dispayling quality is wrong (the client show the
file which the gray balk at the end of file at
bottom) but if i´m setting the compression
factor to 98
all the jpg file can be displaying but with anti-aliassing.
It´s possible that i improve something anywhere ? if yes thanks in advance
As you've discovered, JPEG is a very poor
(inefficient) codec for video streaming. Note
that a 227 kByte JPEG frame will take up more
than 150 RTP packets (assuming the default MTU of
1500 bytes) - all of which will need to be
received without packet loss in order for the
receiver to be able to properly render the frame.
My first suggestion would be to use a better
video codec (e.g., MPEG-4 or H.264).
(I assume you've increased
"OutPacketBuffer::maxSize" to allow for your
large input frames (otherwise you will have seen
error messages). And that your receiver's input
buffer is also sufficiently large.)
