Privet!

Hmm, interesting things...
When i debug, i se only printf 'before trickplay' and
program delays for a while and then says that can't
start Trickplay (as i wrote in previous mail).
There is a code cut
-- cut from code --
    dvb->SetTP(dvb->chans[iIndex].tpid, dvb->chans[iIndex].satid);
    dvb->set_front();

    sleep(1);
    printf( "testing after sleep, before trickplay\n" );

    //Launch the demux
    m_pTrickPlay->Create();
    printf( "testing after trickplay\n" );
-- end cut --

also, i try add printf to DoWork() of NormalTrickPlay
but also nothing printed out :( Why thread do not start???

and one more, i try to change place for m_pTrickPlay->Create()
(after SelectPid) and i got a SegmentationFault...
Possible it is a correct...


my configure line:
./configure --enable-dvb --with-dvb=/root/make/linuxtv-dvb-1.0.0-pre2/
