Description

I have wrong command for normal CI CAM ( not CI+ compatible cam)

2021-06-02 08:14:58.073 [ TRACE] en50221: dvbca0-0: pcmcia data rate set to 00

Look at this peace of code:

in src/input/mpegts/en50221/en50221_apps.c :

app->cia_info_version = atag & 0x3f ;  // 0x9F8021 / 0x9F8022 / 0x9F8023 with mask 0x3f gives: 0x21/22/23
    CICAM_CALL_APP_CB(app, cisw_appinfo, atag & 0x3f, s, type, manufacturer, code);
    if (app->cia_info_version >= 3) /* at least CI+ v1.3 /                  <------------ *is always true ......
      if (CICAM_CALL_APP_CB(app, cisw_pcmcia_data_rate, &rate) >= 0)
        return en50221_app_pdu_send((en50221_app_t *)app, CICAM_AOT_PCMCIA_DATA_RATE, &rate, 1, 0);

so I had to modify correct value :

app->cia_info_version = atag & 0x0f ;
