Hi All, I am trying to install VDR on my NAS, a D-link DNS-323. This goes great, I can play & record unencrypted channels. without any problem. Next I try to compile the connax softcam plugin, as per this guide: https://wiki.debian.org/VDR#Install_vdr-plugin-sc_and_libvdr-sc-cardclient_f...

am not sure if softcam is a legal topic on this list, but I would advise you to take a look at the dvbapi plugin instead of sc. I am not sure if it will fix your problem, though - but it is a way more stable and better solution in my opinion.

I had to go softcam to support Conax as well as there were no hardware CAMs available at the time.

Hi Vidar,

I have compiled the dvbapi plugin, and installed it. VDR runs the plugin, so far so good. Dvbapi tries to connect to oscam via /tmp/something. Can dvbapi be configured to access oscam via network?

Regards, Cedric

Not to my knowledge, though you might be ale to hack something together. OSCAM does not require much to run, but I realize you are on a very limited platform.

A slightly different topic, but I can imagine decrypting a TV station can be CPU consuming. I expect the NAS to be too slow to decrypt multiple streams at once. Is it possible to record a TV program as an encrypted .ts file? Is it possible to decrypt the file afterwards? Is it possible to only decrypt a TV signal white watching live?

Tonight I will test if VDR records an encrypted show as-is when no OSCAM is available. It looks like streamdev just sends the encrypted file to the browser. On my PC I see the buffer fill with 400KB/s, but no moving image, so I guess it sends it encrypted.

Best regards, Cedric

It looks like tsdecrypt can decrypt a .ts file: http://georgi.unixsol.org/programs/tsdecrypt/

I have removed libvdr-dvbapi from /usr/lib/vdr/plugins/. VDR does not write an encrypted file to my hard drive. I have downloaded and compiled tsdecrypt. Then I do the following actions (each in a separate terminal). Oscam is running on another PC tzap -a 0 -r 'Discovery Channel' cat /dev/dvb/adapter0/dvr0 > in.ts After some time i do this: ./tsdecrypt -I file://in.ts -O file://out.ts -s 192.168.31.111:15050 -U user2 -P password2 -B 000102030405060708090A0B0C0D -C 0B00 -D 3 -c CONAX -p 2013-12-23 22:05:54 | Syslog : disabled 2013-12-23 22:05:54 | CA System : CONAX 2013-12-23 22:05:54 | Input file : in.ts 2013-12-23 22:05:54 | Output file: out.ts 2013-12-23 22:05:54 | Out filter : disabled (output everything) 2013-12-23 22:05:54 | TS discont : report 2013-12-23 22:05:54 | Decoding : single thread 2013-12-23 22:05:54 | CAMD proto : cs378x 2013-12-23 22:05:54 | CAMD addr : 192.168.31.111:15050 (IPv4/IPv6) 2013-12-23 22:05:54 | CAMD user : user2 2013-12-23 22:05:54 | CAMD pass : password2 2013-12-23 22:05:54 | EMM process: No 2013-12-23 22:05:54 | ECM process: Yes 2013-12-23 22:05:54 | ECM report : 60 sec 2013-12-23 22:05:54 | CW warning : 60 sec 2013-12-23 22:05:54 | Start tsdecrypt v10.0 (release, build 2013-12-23_21:37 libdvbcsa) 2013-12-23 22:05:54 | CAM | Connecting to server 192.168.31.111 port 15050 2013-12-23 22:05:54 | CAM | Connected to server 192.168.31.111 port 15050 (addr=192.168.31.111 fd=5). 2013-12-23 22:05:57 | ECM | Received 0 (0 dup) and processed 0 in 3 seconds. 2013-12-23 22:06:04 | PID | 228424 packets with PID 0x0bf5 (3061) Unknown 2013-12-23 22:06:04 | PID | 14548 packets with PID 0x0bf6 (3062) Unknown 2013-12-23 22:06:04 | Stop tsdecrypt v10.0 (release, build 2013-12-23_21:37 libdvbcsa)

According to the README file, I am missing ECMs and EMMs streams: One commonly seen error is not an error in tsdecrypt at all. You have to make sure that the software that streams channels from the DVB card is sending ECMs and EMMs along with other streams. If these streams are missing you'll probably get the following messages from tsdecrypt:

2012-04-02 22:02:12 | ECM | Received 0 (0 dup) and processed 0 in 3 seconds. 2012-04-02 22:03:09 | CW | *ERR* No valid code word was received for 60 seconds! 2012-04-02 22:03:12 | ECM | Received 0 (0 dup) and processed 0 in 60 seconds.

Please configure your software to stream ECMs and EMMs. For dvblast (version 2.0 and above) the correct options are --ecm-passthrough and --emm-passthrough. Note that dvblast 2.1 have broken ecm passthrough so use at least version 2.2.

Let's see if I can get dvblast to work on my NAS :-)
