[dvblast-devel] Problems with some pro CAMs

[NetOne - Doychin Dokov]

I've already played with 1.2, -W and different CAPMT_WAIT time, but am 
not so convinced that is the reason for these malfunctions.

For the sake of being sure, i recompiled the 1.2 with CAPMT_WAIT of 10 
seconds, then run it on the Viaccess CAM with a 3-service config file. 
Here's the output:
debug: adding first CAPMT for SID 10103 on session 3
debug: adding CAPMT for SID 10105 on session 3
debug: adding CAPMT for SID 10106 on session 3
debug: opening DateTime session (4)
debug: DateTimeHandle : interval set to 10
 >> error: couldn't read from DVR device (Value too large for defined 
data type)

I've never seen this error when not using -W. The result is the same - 
only the last service is decrypted. I've monitored the network interface 
while dvblast was starting up, and noticed that no packets get output 
until the *last* CAPMT is added. Could it be that the TS is not fed 
through the CAM while adding CAPMTs, and it's started when dvblast is 
finished adding CAPMTs? Or something like that? I expected to have 
output from the first service, decrypted or not, right  after the first 
CAPMT was added?

Another, I think, very interesting experiment. The test was done with 
latest SVN dvblast. I made a shell script, which adds services one by 
one to the dvblast config file, then reloads the dvblast. I've started 
it with empty conf before running the script, for the sake of 
simplicity. Here's the script:
#!/bin/sh
echo '239.100.9.2:1234 0 10105' >> dvblast.conf
dvb-reload
echo '239.100.9.3:1234 0 10106' >> dvblast.conf
dvb-reload
echo '239.100.9.1:1234 0 10103' >> dvblast.conf
dvb-reload

(dvb-reload is an alias of dvblastctl -r /tmp/dvblast.sock reload)
Please note there's no sleep or wait anywhere in this script. When it's 
started, CAPMTs get added as fast as possible, in a second or so. All 
three services get decrypted at once, and are running fine.

I made another experiment, removed the first two 'dvb-reload' lines, so 
the script just adds all three services to the config file, and signals 
the already running blank-conf dvblast to reload. The result - again 
success on all services. At the end of the mail is the output of the 
dvblast when signalled to reload.

So, maybe we don't add multiple CAPMT correctly? It's clearly not a 
module timeout issue, as a wait of even 10 sec does not help mitigate 
the issue, and it does function okay when configured through the reload 
trick. Couldn't we make dvblast do what it does when adding CAPMTs on 
config reload?

If I can do anything more to help get this issue fixed, please let me 
know. SSH access available upon request if someone is interested.

Kind regards,
Doychin
