VDR does not handle well TBS 5520SE multiple frontends

  • Hi,


    I know that there is already a subject opened about a similar issue (link), but this one is actually a bit different.

    This card has 2 signal inputs (one for terrestrial and one for Sat).

    At the end, the TBS driver creates only 1 adapter but with 2 frontends.


    VDR seems to discover them well:

    Code
    Oct  9 15:16:18 nuc vdr: [11352] probing /dev/dvb/adapter0/frontend0
    Oct  9 15:16:18 nuc vdr: [11352] frontend 0/0 provides DVB-T,DVB-T2,DVB-C,ISDBT,DVB-C with QPSK,QAM16,QAM32,QAM64,QAM128,QAM256 ("TurboSight TBS 5520SE DVB-T/T2/C/C2/ISDB-T")
    Oct  9 15:16:18 nuc vdr: [11356] frontend 0/0 tuner thread started (pid=11352, tid=11356, prio=high)
    Oct  9 15:16:18 nuc vdr: [11352] probing /dev/dvb/adapter0/frontend1
    Oct  9 15:16:18 nuc vdr: [11352] frontend 0/1 provides DVB-S,DVB-S2,DSS with QPSK,QAM16,QAM32,QAM64,QAM128,QAM256 ("TurboSight TBS 5520SE DVB-S/S2/S2X")
    Oct  9 15:16:18 nuc vdr: [11359] frontend 0/1 tuner thread started (pid=11352, tid=11359, prio=high)


    The thing is that it does not handle them well.

    When switching from one to the other, it seems to think that there are actually 2 demuxes...



    Has anyone experienced this ?


    Thanks!

  • Create the symlinks as descibed in this user manual: tbs5520se_user_guide.pdf - then you should be able to switch between the satellite and the terrestrial frontend.

    I think, there is only 1 demodulator as in the TBS6590, so you can only use one frontend at a time (e.g. recording on one and life viewing on the other is not possible).

  • Thanks I have 'almost' the same issue as described, when using symlinks.


  • It looks like VDR is trying to access to both frontends and does not (yet) know that only one frontend can be used at the same time.

    Try to disable EPG scan (EPG scan timeout = 0).

  • Hello,


    I'm using a TBS 6522 Multistandard card. DVB-S is connected on the

    second Input.



    Just to mention....
