I was talking about using the dvb api, that would be nice to have for the dektec cards. of course, you can get the data using a pipe. one can do: create a named pipe: # mkfifo fifo.ts # run dvbsnoop: dvbsnoop -s ts -if fifo.ts # feed the fifo DtRecord fifo.ts bye, rafael diniz > > Em Friday 10 October 2008, Daniel Glöckner escreveu: > >> On Fri, Oct 10, 2008 at 02:09:08PM +0200, luisan82@xxxxxxxxx wrote: > >> > I've been trying to analyze a ts with dvbsnoop through an ASI input > >> > unsuccessfully. > >> > When I execute dvbsnoop, it tries to read from a location > >> > (/dev/dvb/...) wich doesn't exists. > >> > >> The drivers provided by DekTec do not implement the Linux DVB API. > >> You can't use dvbsnoop. > >> You need to write your own program using their proprietary DTAPI > >> library.
