Hi, I have been using DVBLast in a production environment for the last few years, great software and super stable.

I am demultiplexing a MPTS udp source and sending the individual demuxed programs to local ffmpeg instances for further processing via udp, all works ok and it has been working fine for the last few years. The problem I always have had is that whenever I have to restart the ffmpeg instances the log is full of messages like this:

error: couldn't writev to 192.168.3.201:2500/udp (Connection refused)

The messages are produced at a rate of 5 per second, so, since the MPTS has 6 channels and the ffmpeg takes a few seconds to restart whenever that happens the log is filled with 100 to 150 log lines with the same message, I have tried all -quiet options and the message always appear.

Is there any way to avoid "error: couldn't writev to....." messages being produced or decrease the frequency of them?

Thanks in advance.
Salva.

PS: DVBLast versión being used is DVBlast 3.4 (release) and OS is raspbian (Ubuntu) on a Raspberry PI 3B+

Hello!

I started dvblast in the configuration file is a SID(among others) for which it does not ffdecsawrapper authorization.
Programs for which authorization has ffdecsawrapper are decoded (visible in oscam_web), but can not be played(vlc).
Subject to dvblast.conf such a SID is not, everything ok.
???

Can dvblast receive DVB-S2X Frames?

Hi, I am new with DVBlast. I'm finding solution to convert stream (format: http://ip:port/udp/udp_ip:port) to DVB-T for DVB set top box. Can DVBlast do it? Sorry if I did something wrong. Thanks all

if we write output address in the form ip:port (without @interface or /option/option ...),
despite we have provided --provider-name sth. on the command line,
the program reaches dvblast.c:196

if ( psz_string == NULL || !*psz_string ) goto end;

and the function config_ParseHost returns, without setting p_config->psz_service_provider.
As a result the provider name isn't changed.

That must happen on dvblast.c:262:

if ( !p_config->psz_service_provider && psz_provider_name )
    p_config->psz_service_provider = strdup( psz_provider_name );

where psz_provider_name is the command line argument.

Hello, I have a SkyStar USB 2 HD CI and CAM TechniCrypt Irdeto CI +. The module reads the card and decodes well over time restarts. This is repeated. The same happens with the CAM Mascom Irdeto "cryptoworks". In other applications (VDR, gnutv) modules do not fall. Can anything be done?

edit:problem solved: "always on" = 0 for all.

Hi

I am searching for the syntax to use dvblast for http unicast but proved futile. All the tutorials and article only showed multicast syntax.

I would appreciate it if you could show me the syntax for using dvblast for http unicast. Many thanks

Hey there, been battling last 2 days and have run out of resources to read... I'm trying to stream off my satellite LNB 10750 to get freeview here in NZ.

It starts but nothing is streaming and if I check my router no joins/groups are made on that multicast, though if i test from VLC on my laptop the router shows them. I think the issue is more that the content is not actually there as its not using 10750 for LNB settings; how does one set this? Everything is running fine in tvheadend and then I disable it to try get dvblast working (tvheadend was just to make sure the card worked etc)

They must be specified explicitly:

I have found a possible missing of "freeing memory" on "ConditionalAccessClose".

During call of "ConditionalAccessHandle" the function allocate memory for "system_ids" :

        p_ids->i_nb_system_ids = l / 2;
        p_ids->pi_system_ids = malloc( p_ids->i_nb_system_ids
                                        * sizeof(uint16_t) );

After removing the DVB-CI slot cam the prevoius allocate memory is not "freed".

    msg_Dbg( p_access, "closing ConditionalAccess session (%d)", i_session_id );
    free( p_sessions[i_session_id - 1].p_sys );

the memory allocated for system id is not released.

I guess the right code should be:

    system_ids_t *p_ids =
        (system_ids_t *)p_sessions[i_session_id - 1].p_sys;           
    
    if ( p_ids->i_nb_system_ids )
        free( p_ids->pi_system_ids );
	
    msg_Dbg( p_access, "closing ConditionalAccess session (%d)", i_session_id );

    free( p_sessions[i_session_id - 1].p_sys );

Am I right ?

I am using DVBlast release 2.2.

In config file I have following line:
239.8.1.4:[email protected]/udp 1 0 1077,3324,7088
So I want to output only PIDs: 1077,3324,7088, nothing more.
I run the DVBlast with following command:
./dvblast -D 239.0.0.3:2111/udp/ifaddr=10.8.8.1 -c config.cfg -l &
Unfortunately I got on output the empty PAT table (without any entries in program loop)

Is it possible not to output any PAT table? Is it known issue, or I am doing something wrong?

Seen with latest dvblast version 3.4.

Example to reproduce:
First start dvblast:
dvblast -u -d 127.0.0.1:25000 -f 12100000 -s 27500000 -m psk_8 -n 0 -a 0 -r /tmp/dvblast.sock
Next launch dvblastctl:
dvblastctl -r /tmp/dvblast.sock -x xml fe_status

During execution of dvblastctl, dvblast throws the following errors and no signal strength, SNR and BER values are returned:
error: ioctl FE_READ_BER failed (Operation not supported)
error: ioctl FE_READ_SIGNAL_STRENGTH failed (Operation not supported)
error: ioctl FE_READ_SNR failed (Operation not supported)

Looks like deprecated kernel calls are used in "dvb_FrontendStatus", see:
https://github.com/gfto/dvblast/blob/master/dvb.c#L1493

Will this be corrected ?
Thanks for any comment!
Michel Vanden Broecke

can it be used for dvb-c? cable tv for EPG and boque the channels?

Hi,

It is necessary to change MIS=9 to MIS=8 in line 994 "#define MIS 9" to pass correctly the stream id to the tuner card because :

static struct dtv_property dvbs2_cmdargs[] = {
{ .cmd = DTV_DELIVERY_SYSTEM, .u.data = SYS_DVBS2 }, // 0
{ .cmd = DTV_FREQUENCY, .u.data = 0 }, // 1
{ .cmd = DTV_MODULATION, .u.data = PSK_8 }, // 2
{ .cmd = DTV_INVERSION, .u.data = INVERSION_AUTO }, // 3
{ .cmd = DTV_SYMBOL_RATE, .u.data = 27500000 }, // 4
{ .cmd = DTV_INNER_FEC, .u.data = FEC_AUTO }, // 5
{ .cmd = DTV_PILOT, .u.data = PILOT_AUTO }, // 6
{ .cmd = DTV_ROLLOFF, .u.data = ROLLOFF_AUTO }, // 7
{ .cmd = DTV_STREAM_ID, .u.data = 0 }, // 8
{ .cmd = DTV_TUNE },
};

Hello dvblast team,

when I add new service to config and reload using dvblastctl, ECM pids are not included in the newly added stream even when I have used -Y option when starting dvblast.

Can you please fix this?

Hello,

Is possible add feature (or add to README / Man page) how select DVB-C or DVB-T on dual DVB-CT cards?

We have such cards and they are after load default in DVB-C mode and we can not select T mode by dvblast, so for now we using work-around and after boot-up we run for few seconds "vlc" just for switch such card to DVB-T mode.

Could be handy if dvblast will have such feature.

Hello.

Possible add DD CI support to dvblast?
I can test and give access to my hardware for more analyze...

Sample implantation can be found here
https://github.com/vinwareznic/astra-4/blob/master/modules/dvb/ddci.c
and here for VDR (VDR 2.2.0 supports it direct)

It seems that if a program number and ip address are added to the conf and the channel is not being sent then the PAT is created and sent.

If this is correct is there a way for this feature to be disabled?

Hi, can anyone tell me please what is the spupid that I see in the documentation, for option -0?

-0, --pidmap <pmtpid,audiopid,videopid,spupid>

The README says:

4. PID remapping

All four PIDs are required!

Is this the Subtitles PID? If yes, what happens if the Service doesn't have subtitles?

Thank you very much in advance, regards

Supports dvblast sending the pin into CI/skylink card? We have some stations (r.g. Horror cahnnel) with parental lock/pin. We cann't remove pin from card.

Hey, how you can use dvblast with unicable?
