Problem with dreamstart and recording

Postby dvdfreak » Mon Feb 25, 2008 11:55 am

Hi!

There seems to be a problem with PIP recording and plugins. Here's what I tried, and what also works:

dreamstart /chname='VT4' /renderless=on
dreamstart /startpiprec_chname='VT4'

However, this doesn't work:

dreamstart /chname='VT4' /renderless=on
dreamstart /startpiprec_chname='KANAALTWEE'

I'm using Acamd to decode the TV Vlaanderen channels with my smartcard. In the first set of commands I can see that Acamd gets the channelchange and starts decoding the channel:

19:53:13: Ch: 953 - VT4
19:53:13: Incomming PackageSize [184]
19:53:15: 0x03B9 0x31E5 0x0100 0x0000006C 0x03CD 0x00B6 11010010

In the second set of commands Acamd initializes fine, but never seems to get the channel change.

I did notice that Acamd starts to decode the channel even when I only use:

dreamstart /chname='VT4' /renderless=on

So a PIP recording of this same channel works since it's already being tuned to and decoded. A pip recording of another channel fails since the pip01, pip02,... plugins never get notified of a channel change!

Does this make any sense? :-)

Thanks for looking at this problem!

I also see this bug

Postby johandm_be » Mon Feb 25, 2008 5:31 pm

Hi,

I can confirm I also see this bug. It also happens if you use it directly (w/o command line)

Here is another way of reproducing it:

1) run dvbdream
2) tune to a scrambled channel, for example VT4
3) right-click "Record On"
-> recording of the channel starts OK

4) right-click PIP, and select another scrambled PIP on the same TP, for example VTM

-> the PIP window opens, but there is no video. The newcamd server does not see a login for the 2nd (PIP) client !!!

5) right-click "Record On" in the PIP window
-> a file is created but as expected, it does not play.


Now: close dvbdream, and do the following sequence:

(be sure to exit dvbdream after the previous test)


1) run dvbdream
2) tune to a scrambled channel, for example VT4
3) right-click PIP, and select another scrambled PIP on the same TP, for example VTM
-> now you do see video in the PIP

4) right-click "Record On" in the main window
-> recording of the channel starts OK

5) right-click "Record On" in the PIP window
-> recording of the 2nd channel runs OK and simulatenously



So: once a recording of a scrambled channel is going on, additional PIP that use an MD plugins don't work anymore...
This problem does not happen if the PIP channels are FTA.


Note I also saw such a problem in v1.04h; the version I tested before that (don't recall which one that was) did not have this problem.


Hope this is clear, please let me know if I can provide more info.

Thanks,
Johan.

Any update on this? This is really a blocking issue for me :(

here are some logs from my system

Postby johandm_be » Tue Mar 04, 2008 9:27 am

Hi,

I have done some tests to reproduce and document this issue.
FYI: my plugins are CSC 4.0.0.2, connecting to a newcamd server with a phoenix card reader.

1) LOG1 :
* I manually start DD, tune to VTM, then select PIP -> VT4
=> both (scrambled) main channel and PIP show correct video

2) LOG2 :
* I manually start DD, tune to VTM, then start recording, then select PIP -> VT4
=> VTM shows fine, there is no video in the PIP !
=> I can also see that there was no login for the PIP on the newcamd server

3) LOG3 :
* similar, but from the command line:

dreamstart.exe /renderless=on /chname=VTM
dvbdream.exe /startpiprec_chname=VT4
dvbdream.exe /startpiprec_chname=VTM

=> both channels record fine.

4) LOG4 :
* again from the command line:

dreamstart.exe /renderless=on /chname=VTM
dvbdream.exe /startpiprec_chname=VTM
dvbdream.exe /startpiprec_chname=VT4

=> VTM records fine, VT4 is a scrambled recording and cannot be played back!

(the difference between log 3 and 4 is the order in which the recording was started. After recording of VTM (=main video) is started, PIP recording no longer works)

I hope these logfiles help you debug this. I am building a PVR system based on DD but this is really a showstopper.
Other than this issue, DD has proven to be very reliable to work with.
Of all software that I have tested, it really is the best I have seen.

Thanks!

-> it appears like log 1 calls a procedure "ShowPip(chid:3146)" where log2 calls "StartMultipleRec(chid:4320)". The "ShowPip" clearly does "[MDAPI] Command"s after loading cs1.dll, but "StartMultipleRec" does not do that.

Does this help/make sense ?

Thanks!

This is really a blocking bug for the PVR solution I'm working on. I'd love to fully support DVB Dream as a recorder, but is there any chance this problem will be fixed?

Thanks!

For The Record released!

Postby dvdfreak » Thu May 29, 2008 4:47 am

Bad news: nobody ever took any notice of the bug reported in this thread :(

Good news: we found a reasonable workaround to support DVB Dream so I am proud to announce For The Record has been released! :D
