[Live-devel] [live-devel] Stange problem

[Lukasz Kondrad]

Hello Ross,

I transmit two rtp streams over dvb-h. The first one is generated by
H.264real time encoder (envivio 4caster M2) and send on multimedia
server
(cardinal), the second one is generated from a mp4 file by multimedia server
(cardinal) by itself.
I receive it on linux machine with dvb card. I set dvb network adapter on
proper pid, i tune the card and by tcpdump I see that IP datagrams from
which carry both rtp streams are received by the network adapter. I run vlc
with sdp files. The strange is that I am able to receive the rtp stream
generated by H.264 real time encoder but not the one which multimedia server
generates. I am quite confused and I don't know what is the problem. Below I
presents the sdp files for both streams, maybe there is something what
live555 don't take into consideration.

I thought that the library doesn\t look on proper card but why once it takes
the rtp packets from the card and for the second stream it doesn't.
