T2MI

    • T2MI

      Some broadcasters use T2MI encapsulation for distribution. Some boxes already have direct support. Dreambox processes this signal with the help of the astra-sm utility.

      astra-sm needs for its activity:

      Quellcode

      1. :~# opkg install astra-sm
      2. Installing libaio1 (0.3.112) on root
      3. Downloading http://188.165.252.42/feeds/satdreamgr-10/armv7ahf-neon/libaio1_0.3.112-r0_armv7ahf-neon.ipk.
      4. Installing libdvbcsa1 (1.1.0) on root
      5. Downloading http://188.165.252.42/feeds/satdreamgr-10/armv7ahf-neon/libdvbcsa1_1.1.0-r2_armv7ahf-neon.ipk.
      6. Installing astra-sm (0.2+git1957+44bcd28) on root
      7. Downloading http://188.165.252.42/feeds/satdreamgr-10/armv7ahf-neon/astra-sm_0.2+git1957+44bcd28-r0_armv7ahf-neon.ipk.
      8. Configuring libaio1.
      9. Configuring libdvbcsa1.
      10. Configuring astra-sm.
      12. http://188.165.252.42/feeds/satdreamgr-10/armv7ahf-neon/libcrypto1.1_1.1.1l-r0_armv7ahf-neon.ipk

      We manually insert the files:

      Quellcode

      1. ◦ /etc/astra/astra.conf (chmod 644)
      2. ◦ /etc/init.d/astra-sm (chmod 755)
      3. ◦ /usr/bin/astra (chmod 755)
      4. ◦ /usr/bin/t2mi_decap (chmod 755)

      Manually make some adjustments:

      Quellcode

      1. ◦ First, Enigma2 must be terminated via shell:
      2. ▪ systemctl stop enigma2
      3. ◦ open the lamedb file from the package and enter the relevant data in the /etc/enigma2/lamedb file and save it again.
      4. ◦ open /etc/enigma2/bouquets.tv in the box and enter the following line in full:
      5. ▪ #SERVICE 1:7:1:0:0:0:0:0:0:0:FROM BOUQUET "userbouquet.some_t2mi.tv" ORDER BY bouquet
      6. ◦ Start Astra-SM (there are several variants, here is just one of them via shell:
      7. ▪ systemctl enable astra-sm
      8. ◦ You should now reboot via shell:
      9. ▪ reboot

      The problem arises with the use of the appropriate library


      PS: After replacing the astra file, the problem was no longer there :thumbsup:
