As an introduction, the purpose of this forum is to discuss the use of the mvpmc project's dongle.bin as a GB-PVR client. More specifically I would like to see discussion's of the mvpmc option I call "Emulation Mode" as an alternate to the standard Hauppauge client in their dongle.bin.

I originally added this function as a "proof of concept" but I decided to expand on it when I found I was able to do things mvpmc couldn't do thanks the power of GB-PVR. There are also things I feel mvpmc does better, at least for me, so there was a logical fit. I will open a separate thread on how to install mvpmc to gather feedback but it is quite simple.

I have now got emulation mode working to the point where it is useful but still not as stable as the Hauppauge client, but I don't see any reason it can't be equally or more stable. The mvpmc team probably know the hardware as well as Hauppauge does and I just need to understand a few things better then I do now in order to fix the stability issues. I will looking into getting some help from GB-PVR users in reaching this goal and looking for serious feedback and critique. Don't be kind.

Because of stability I have been reluctant promoting mvpmc or emulation mode, other then highlighting possibilities, but recent discussions on the future direction of mvpmc make it clear that GB-PVR users could benefit if this development continues. Jon Gettler, the project lead has said that the focus of mvpmc will be shifting to make the architecture open enough to run on other platforms, possibly game consoles and mini-ITX devices , but we still want to focus on embedded linux devices. With these new devices offering HD video, and more native a/v protocols, I am very hopeful. I have the same faith in Jon as I do in sub, in being able to deliver amazing things.

I expect there will be other discussions on when to use mvpmc's native capabilities instead of GB-PVR's, but it is not a contest and I want to see pros and cons discussions and not "fanboy" responses. If any of you read avsforum when different products are compared you will know what I mean.

I will be particularly interested in where GB-PVR users want to go, especially with your option of using the GBPVR client. Clearly I do not see a need to discuss anything about MythTV here, and I couldn't help you anyway because I don't use it.

Finally the mvpmc project does have its own web site and wiki respectively at

http://www.mvpmc.org/
http://mvpmc.wikispaces.com/

Because the history of mvpmc has typically been aimed at Linux and MythTV users, some of you may find these hard to follow. I actually gave up trying to load the mvpmc dongle on several occasions, so if you get lost come back here.

Thanks,

Martin

Would this work like a dongle we couple drop into the GB-PVR folder and select through the config? Or would I need to tftp a new firmware into the unit?

1. Unplug the mvp from power
2. Put the mvpmc dongle .bin into the "dongle" directory of gbpvr
3. Change to this dongle in config
4. Replug the mvp to power
5. See it loading ... needs some time, maybe over one or two minutes.
6. Choose emulation mode

i've used the MVPMC dongle soon as i saw the emulation mode way back when..Smile
worked fine...just put in the dir and select it in gbpvr config...
i'm sure he'll put up a write up soon about installing/using it..really pretty selfexpainatory..just try it..Big Grin
i should see what improvements have been made as it's been a year about since i tried it last...[lately i'm using client mode and the pc for viewing..]

i remember it working quite well, tho lacking a few capabilities i hope are now added...

i'm looking into making a client version running on bartpe for xbox..Smile
[already have client running on bartpe cd for diskless pc client]

wondering if client mode has opened up any new possibilities for MVPMC?

looking forward to your further development..Big Grin

Jeff, here is the GB-PVR message that really started this off

http://forums.gbpvr.com/showpost.php?p=1...ostcount=9

Stability aside, to summarize the specific advantages might be:

- wide screen signaling.
- Wake On LAN
- improved recovery from FF/RW on MPEG1 files.
- working volume controls.
- (I believe) better video buffering
- remote power off
- fewer network overruns and collisions

The real advantage will come if I can improve stability and this will run well on newer platforms.

plus you can use it's internal player for upnp,other servers and direcct acces to other file formats, including vobs with ac3 audio inside.. Smile

plus streaming from web with vlc as server on server machine..

i'm sure there's other things i am forgetting..

and it works great as a gbpvr dongle without any real hoops to jump thru..
[switchable from the remote]

it's functions are mostly native in hardware [not server based] so it opens up other possibilitites for future...
i'd love to see web browsing with tab and clickable links sometime...

oh and speed...native functions means hardware speed...
[not needing to convert formats on server first etc.]

Actually mvpmc can already do web browsing because it can be configured to be a VNC client. In fact, I just extended this by adding the extensions for the Hauppauge/GB-PVR GUI interface. Unfortunately the resolution of the MediaMVP at 640 x 480 or 576 doesn't provide a great web experience, even if you set the VNC host to the matching resolution.

It is a part of an mpeg stream that tells mvpmc to automatically toggle from 4:3 to 16:9 aspect ratios. I've never seen it here in any NTSC file, but I've been sent some PAL DVB streams that do change during commercials.
