Emulation mode - 1.08 Update

[mvallevand]

I have updated the alpha mvpmc with small improvements to deal with changes in GBPVR including changes PVRX2's improvement. This code will be incorporated into the mvpmc code base tonight and will be available in the mvpmc nightlies beginning with 07/07/07 and in the full 0.3.4 version when it is available.

For GBPVR note that inset video is no longer supported by sub. With the tremendous improvements in PVRX2 I assume over as short time most of you will be migrating, but if you have any comments please indicate if you are using GBPVR or PVRX2

The emulation code changes did get built last night, so the 2007-07-07 nightly is probably the better dongle to use. Looking at the about screen I noticed I have a lucky version too. The automated buiild was at 0300 EDT which is 0700 UTC. so 07/07/07:0700 !

This will allow me to continue to improve the alpha version without impacting what there is today. For those using yesterday's alpha there is no reason to upgrade.

I addition to the nightly, sub's survival guide links to

Now I will attempt point to the version that you feel is best. Now it is the nightly.

I have uploaded my first alpha for 1.0.8 to potentially address some problems when PVRX2 returns less data then requested as discussed in this link

Ideally PVRX2 should do the buffering, since I have placed an arbitrary timeout of 7/10 of a second on this which may be too much or too little. Hopefully this is a temporary solution.

Ideally PVRX2 should do the buffering

It does. If there isnt as enough data available to fulfil the request, it waits a bit and checks again. It does this a few times, then eventually returns whatever it can. It'll usually only return a partial data buffer when its reached the end of file. The next request would typically return zero bytes.

I don't know if you saw the log I posted here, http://forums.gbpvr.com/showpost.php?p=2...ostcount=7 but it looks like the buffering seems to change after show transition in live tv. This update gets around this by waiting a bit on short reads and requesting another read even when you return zero. I'd like to see just a little longer wait at this point since as the mvp plays out its mux you should actually have more time to pre-buffer and I think you do, but once the pre-buffer is empty the short reads start.

Just like to report that the 2007-07-11 Alpha mvpmc dongle seemed to take a lot longer after "Starting Application" appears than the previous one (which also worked ok with PVRX2)

Haven't tried 2007-07-17

k. I haven't changed the startup code and I don't see any difference so I'd like to see the MVP- logs that go with this. I think you should also look to see if any plugin, skin, or patch you've added since the release might be causing this by going back to the dongle in donglex2a.

Here's my current startup time (using the mvpmc debug output) This seven seconds is very typical, with a screen in under a second.

Code:

08:25:43 Starting Application
08:25:44 Emulation timer started
08:25:44 Received RDC command RDC_SETTINGS Settings command 0
08:25:44 Received RDC command RDC_SETTINGS Settings command 3
08:25:44 YUV2 update 44 0 640 480
08:25:44 Timer 0 New Session - 0 5000
08:25:44 Received RDC command RDC_SCALE
08:25:45 Timer 0 OSD  0 5000
08:25:50 Timer 0 Ping - 10 5000
08:25:50 Handle Ping
08:25:55 Timer 0 OSD  0 5000

I tested here, no difference in the 11-07 and 17-07 dongle overhere. "Starting application" takes about 1-2 secs.

OK, I'll try and remember how to add the debug logs for mvpmc (assume those are what you need). I have also installed every PVRX2 patch sub has thrown up the latest being this one from today 18 July.

For now the server side log will be fine. The results I showed were on the comskip patched PVRX2 too.
