Hi,
I'm currently implementing a streaming server which will stream (part of) the
TS received from /dev/dvb/adapter?/dvr? to a multicast socket. I'd like to be
as efficient as possible, so I took at look at the splice() function
implemented as of Linux 2.6.17 and it looks promising as for most cases I
could splice() the data from the dvr device directly to the socket. There
might be two problems though:
- Is there a splice() patch for the DVB drivers?
http://lwn.net/Articles/178199/ suggests that doing such a thing is possible,
but I havn't found an implementation yet.
- Is there a way to do a read() from the dvr device without removing the data
from the queue (i.e. an equivalent for recv()/MSG_PEEK)? I'd need that to
know the PID of the the TS packet.
Thanks for any hint...
Cheers, Johann
already done: dvbstream from cvs can already stream to multiple
unicast/multicast/file streams
repeating pids to each of them, and it's very lightweight (although I
have to admit it's a bit untidy).
