IRecordingSourceConfiguration.Load

[alibert]

Hi,

i'm writing a plugin for a capture source. My config class implements the "IRecordingSourceConfiguration" interface.
There are three methods to manage the settings of the capture source: "Save", "Load" and "Delete". Two of them, "Save" and "Delete", provide a database connection as parameter, but "Load" doesn't?

Maybe I misinterpret the interface, but I have created a new table in the database (similar to BDA_RECORDING_SOURCE and GO7007SB_RECORDING_SOURCE), where I store the settings and values specific to my capture source. Storing works fine, but now I came to the point that those values need to be read out again from the database.

So, my question is, if it is intented to save and load the configuration for an external capture source in the database or not?

I do have a reason for this, but I've only been awake for a couple of minutes, so this reason escapes me at the moment.

Even though I use database for storing my capture sources. I prefer you use XML files (or similar) for saving your capture source configuration. The will save a me potential headaches at upgrade times etc.

What type of recording source are you writing?

Hi sub and thanks for the quick reply,

Yes, a xml-configuration was also my second thought and is already in progress.

What type of recording source are you writing?

I'm writing a plugin for the "dbox2", a digital satellite or cable receiver which can be connected via ethernet. So this will be mainly a streaming client. MythTV or VDR have already plugins for the dbox, too.
The recording part is already done and works quite well, but I still have problems with live tv. As far as I can see, in the interface, the getPreviewGraph function is used for live tv. I've never done things like that, maybe you could give me a hint what to do there.

Another problem is, that the channels of the dbox are represented as hex values (something like "44d00016dcc"). Is it possible to access the functionality of "Map digital channels to epg channels" for that purpose? Translating the hex numbers to integers would result in an overflow.
Currently I use a separate file where the gbpvr source channel numbers are mapped to the hex values.

getPreviewGraph is used for live tv if 'live preview mode' is enabled in the config app. For this to work, you need to construct a nearly complete directshow graph, to which GB-PVR will add the video/audio renderers. The way you'd construct this graph depends on what type of video your getting out of the dbox2.

If you disable live preview mode, then you dont have to do this. Instead you'd just need to record the specified MPEG2 files, and GB-PVR will play them.

Is it possible to access the functionality of "Map digital channels to epg channels" for that purpose?

Unfortunately this is not really possible. This functionality is pretty tightly bound to my BDA recorder, and has all sorts of internal knowledge about how the BDA recorder is implemented, extra interfaces etc.

Hi,

some more questions.

(1) The "minutes"-parameter in "startRecording", is it actually used? I'm asking because "stopRecording" is called when a recording is finished, and I don't want to add an extra timer.

(2) The config screen for the recording source is called from within the config app as a modal top-level window. Is there any possibilty to change that so that the config form opens not modal?
I'm askin because the configuration looks at the moment like this, ane one could only map those source channel numbers to the hex values which appear in the gbpvr-config window below.

(3) Is it possible to have multiple audio streams in one muxed file in gbpvr?

No, is no longer used.

Sorry, no I wont be changing this.

Are you producing MPEG2 program streams? Yes, you can have multiple audio streams, but you cant switch between them at the moment.

Hi,

another question.
Is it possible to catch something like an event or a callback every time a recording is scheduled on a capture source?
Or would I have to check this via IScheduleHelper.LoadRecordingSchedule() periodically?

I'm asking because I can wake the pc from the dbox by wake on lan, but not vice versa. But it is also possible to add custom timers to the dbox, so i could add a timer for each recording that wakes up the dbox from deep standby.
