i'm trying to write an application to stream videos like SipDroid, but SipDroid only streams videos with H263 codec. i would like to stream videos with H264 codec and so i've to write a nal header.
i got some informations from here: http://www.networkdictionary.com/rfc/rfc3984.php?page=0%2C0 and i decided to use the fragmented units to stream (5.8. Fragmentation Units (FUs) (page 8)).
i've tried to create a nal header like this:
nal header http://www.networkdictionary.com/images/rfc3984f14.gif
with the following values for the indicator:
indicator http://www.networkdictionary.com/images/rfc3984-3.gif
F = 0, NRI = 2, Type = 28;
and the header:
header http://www.networkdictionary.com/images/rfc3984-4.gif
S=0 (1 at first packet), E = 0 (1 at last packet), R = 0, Type = 1;
The values of the packets are set correctly on client and server side. But i can't read any video stream out of this packets.
the server is a simple java server, that receives the data and write it to a file. i've also tried to show the stream on vlc player, but it also doesn't work.
Does anybody know what the problem is, or what is missing to get a video stream at the server side?
EDIT:
ok, i think i've solved the problem. i've tried to get the header values from a (vlc player) rtp stream. in this stream the packet format depends on the frame size. is the frame size small enough for 1 packet so the packet has to be declared as a single nal packet with following values: NAL header: f 0, nri 2, type 1. if the frame size is bigger than the packet size, the packets get split and the format looks like i've posted in my question.
