  • [Patch] CAM-Tweaks für Multi Channel Decryption

    Zitat von HelmutB

    if the CAM needs additional or special pids then this will never happen because VDR does not care about CI+.

    I don't use vdr now, but other software transfer uri successfully and fast in dvb card with embedded CI and very slow and partially in ddci hardware. So i think needs to care about additional pids in this case. (I don't know about what of pids...)

  • [Patch] CAM-Tweaks für Multi Channel Decryption

    Hi Helmut,

    current implementation ci+ in vdr ignore uri value. But for compliance ci+ specs uri should be pass from CAM to host to every channel swithing. And host should to answer. Every new uri pass to CAM from air by emm or ecm (not speceifed in ci+ specs). Maybe in your case you didn't pass to CAM necessary pids to transfer uri to CAM and so on to host.

    Hi Helmut,

    now my CAM doesn't freeze. Great! Thank you!

    But now i have CRC erors in stream and breaking picture and sound.

    I don't know it's related driver or software, I'll do more tests with other my CAMs.

    Hello Helmut,

    I have troubles with new CAM. In authentication process from CAM receive big tpdu (more 2kbyte). With old CAM it works fine.

    Code
    [36462.589347] [CAM ] rb_read_tpdu (0)(1)[2683] *** (7) 9F9003 ***

    Full log:

    old CAM


    But with new CAM i have error

    new CAM

    New CAM with ordinary dvb ci and kernel drivers works fine too.

    Can you look please, where might be bug?

    Hi Helmut,

    sometimes device stalled with such errors in dmesg:


    Is possible recovery from this situation except disconnect and reload firmware? And where may be source this errors?

    However, with modified drivers i have this strace output: (after about one minute):

    Not so much...

    Hi Helmut,


    great job! :) As I understand, minisatip use kernel functions for read/write, and after your changes number submissions reduse several times.

    All works fine, minisatip logs clear.

    Hi,

    yes, my speedtest showed equal results.

    But in minisatip if input stream more than 20 Mbps, i have distortions and errors in log:

    Code
    [10/02 00:19:54.876 signal]: BW 2056KB/s, Total BW: 36 MB, ns/read 15847, r: 67, w: 1600 fw: 0, tt: 1061 ms
[10/02 00:19:55.842 AD2]: select_and_execute[7]: EOVERFLOW on socket 9 (sid:2) from 0.0.0.0:0 - type dvr errno 75

    EOVERFLOW - means that the data from DVR was not read fast enough. In case minisatip data from AD2 put to WINTV adapter using the function writev()

    WINTV driver report not much load:

    Code
    [80333.877045]  +++ TS-BITRATE : 15.79 Mbit/s, 328.20 CAM-subs/s, URB-load:  0.83%, TS-miss: 12

[80373.874625]  +++ TS-BITRATE : 15.73 Mbit/s, 326.90 CAM-subs/s, URB-load:  0.83%, TS-miss: 12

    Maybe needs to use other write/read method or use low latency kernel - I don't know.

    With real DDCI minisatip have not any problem. Maybe it should be - pcie 1x about four times faster than usb 2.0

    Code
     [10/02 12:22:40.977 signal]: BW 2178KB/s, Total BW: 89 MB, ns/read 1568, r: 31, w: 31 fw: 0, tt: 48 ms

    Can you test much stream load (more than 20 Mbps) to one WINTV adapter at other applications, e.g. VDR?
