==About==

* 10393 series
* /usr/bin/str

==Notes==

* In situations when streaming across middleboxes (switches and other devices) make sure the camera link is the slowest one.
* Example congestion situatation:
''camera <-- 1000Mbps --> Gigabit switch <-- 100Mbps (PC NIC limited) --> PC''
PC might not get all the packets depending on switch's buffers sizes (e.g. for netgear GS105 has 128kB which gets overflowed at image sizes 200+kB)
* Setting link speed examples:
ethtool -s eth0 speed 100 duplex half autoneg off
ethtool -s eth0 speed 1000 duplex full autoneg off
* dump UDP packets log on the camera (tcpdump if installed):
tcpdump -i eth0 -n udp port <someport> -w packets.pcap
* live555 is used by vlc and mplayer while gstreamer is standalone
As UDP has no congestion control there might be several workarounds:
1. patch live555 and gstreamer
2. slow down camera link
* Patching live555 options:
1. Stick close to [https://tools.ietf.org/html/rfc4585 RFC4585] and [https://tools.ietf.org/html/rfc6679 RFC6679], also checkout [https://tools.ietf.org/html/rfc8087 RFC8087] & [https://tools.ietf.org/html/rfc8311 RFC8311]?
2. In live555 make RTCP RR reports sent out by the receiver for every 50 (or any other number) packets received - implement handling this info in the sender (camera)
Implementing 2:
<font size=2>'''RTCP.c:'''
if (fSource != NULL && fSource->RTPgs() == RTCPgs) {
// We're receiving RTCP reports that are multiplexed with RTP, so ask the RTP source
// to give them to us:
fSource->registerForMultiplexedRTCPPackets(this);
} else {
'''// need to register our RTCP instance here it will be passed to MultiFramedRTPSource.c which receive RTP packets'''
'''// just reused the instance for multiplexed packets'''
fSource->registerForMultiplexedRTCPPackets(this);
}
'''MultiFramedRTPSource.c:'''
receptionStatsDB().noteIncomingPacket(...)
'''// insert after this line something like:'''
int pnum = receptionStatsDB().totNumPacketsReceived();
if ((pnum%50)==0){
if (fRTCPInstanceForMultiplexedRTCPPackets!=NULL){
'''// here fRTCPInstanceForMultiplexedRTCPPackets is just reused'''
