Found nothing suspect to me, although I still got a lot of 'Invalid header' messages in both cases (live and file).Compare the logs from playing the stream live and playing back from file.
I do, this is the command line I'm using:Also, try specifying sout to play locally when playing live. This seems to cause vlc to do things slightly differently.
As far as I can tell the linux version of VLC does not use these values for dvb-s.The registry values are :and this is the significations of the values are :Code: Select all
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HCW88bda\DVBS_as_DVBT\198500] ; #8 "dvbs_freq"=dword:AC2A38 ; 11283000 "dvbs_polarity"=dword:2 ; 2 "dvbs_srate"=dword:6B6C ; 27500 "nit_onid"=dword:7E ; 126 "nit_tsid"=dword:9DD0 ; 40400 "nit_nid"=dword:1 ; 1
dvbs_freq : Frequency in KHz
dvbs_polarity : Polarity of the signal (Horizontal=1, Vertical=2)
dvbs_srate : Symbol Rate in MSps, Eg. 27500
nit_onid : OriginalNetworkID,
nit_tsid : TransportStreamId, and
nit_nid : NetworkID of the DVB-S stream.
the "nit_onid" value is the network Id on the satellite
and the "nit_nid" is the terrestrial emulated network Id
in the HKEY directory the "198500" is the terrestrial frequency
In my opinion we have to tell vlc witch network Id and Transportstream to use. I have not yet seen another dvb-s software not needing them.

Nice pickup. I had computer problems earlier today and only just committed the latest changes with Network-id. Added in the above fix as well.I think I corrected something :

hr = tuner->get_SignalStrength(&strength);The messages that come from the module basically say that the graph is working. In earlier versions I included get_SignalStrength but the timeout message is enough to say there is no signal. Any problems up to that stage would give a warning.I tried to force theses values and it gave nothing.
I will compare the messages between the dvb-s and the emulated dvb-t.
Is there a way to check if the graph is working ? or if the tuner is tunning ?

This one finds the channels and seem to be close to your code
Strangely (to me), graphedit and the mediaserver will happily work with the ts file written to the hard drive but won't accept the same thing streamed. So I figure I must being doing something wrong with the streaming - just don't know what.It all depends on what your mediaserver supports. Maybe it does not like TS. Maybe try streaming mpeg PS instead.The part of the magic that's not happening is, I think, a broader VLC issue in that the only thing that will pick up the URL I'm streaming is VLC. My mediaserver won't recognise the http URL. It will recognise it if I use mmsh - but nothing streams.Graphedit won't accept either URL.
... Any thoughts or suggestions?
I haven't implemented IBDAFrequencyFilter and it is not hard but not trivial either as mingw has none of the BDA header files.The direct tuning finds channels but stop working after that
The IDVBSLocator work good
I have allready tried to force QPSK but nothing append.
I tried the comment disecq approach as it was quick and easy to test. But this didn't work.
Do you allready have a IBDA_FrequtencyFilter object ?
Before we go there can you put in a msg_Dbg trace to print out the various parameters (frequency, srate, polarisation etc) and post the output. I'm wondering if all the parameters are getting through.Sorry but this is not working either...
I think there is only the diseqc left...
to test it and every parameter seem to be okmsg_Warn( p_access, "freq: %d",l_frequency );
Don't know which dll but the prototype is in the header file bdaiface.hDo you would like to know if the command line parsing works ?
I put someto test it and every parameter seem to be okmsg_Warn( p_access, "freq: %d",l_frequency );
Do you know in wich dll I can find the "IBDA_FrequtencyFilter::Put_Range" function ?
I'am trying to do dvb-s tuning in vb.net to find what is missing here and I think I have exactly the same problem...
